Many people don’t measure their blood pressure properly at home – here’s how to get accurate readings

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/niamh-chapman-2262829">Niamh Chapman</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/dean-picone-2264237">Dean Picone</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/eleanor-clapham-2264235">Eleanor Clapham</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Measuring your blood pressure at home means you can take readings over several days to get a better picture of your health, instead of one-off measurements at the doctor’s clinic. It’s important you follow specific steps to get an accurate reading. But <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.124.23678">our study</a> found most Australians do not measure their blood pressure correctly at home and very few were told the steps to follow. We have created <a href="https://bloodpressuretoolkit.com/">resources</a> to help people measure their blood pressure at home, understand their readings and take action with their health-care team. <h2>High blood pressure is a big issue</h2> High blood pressure is a major health problem in Australia and globally. <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.51350">One in three Australian adults</a> have high blood pressure, also called hypertension. This is when your <a href="https://www.heartfoundation.org.au/your-heart/blood-pressure-and-your-heart">blood pressure</a> is <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.120.15026">at or above 140/90mmHg</a> (mmHg refers to millimetres of mercury, a standard measurement of blood pressure). High blood pressure is the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10881002/">leading contributor</a> to preventable health issues and early death among Australians because it is the main risk factor for heart disease, stroke, dementia and kidney disease. <h2>Why measuring blood pressure is important</h2> High blood pressure often has no symptoms. So the only way to know if you have it is to measure it. You may also need to check if your blood pressure has lowered after starting medication or if you’re making changes to your lifestyle, such as doing more exercise, giving up smoking or reducing salt intake. Low blood pressure (<a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/blood-pressure-low-hypotension">hypotension</a>) can also be an issue. But blood pressure changes based on how we are feeling, what we’ve eaten or the activities we have just been doing. These normal responses mean our blood pressure can change from minute to minute and hour to hour. This is why there are specific, recommended steps to follow to reliably measure your blood pressure and to be able to compare readings taken days, months and years apart. <hr /> <iframe id="lBVm6" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/lBVm6/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> <h2>Mistakes are common</h2> We surveyed and interviewed 350 people (who were all measuring their blood pressure at home) from around Australia to find out how Australians measure blood pressure at home and if they receive any education to help them know what to do. Our study found no one followed all of the specific, recommended steps to measure their blood pressure. Instead they said they measured their blood pressure at different times of the day after doing different things. We found most people measured their blood pressure while sitting down (90%) and with the cuff on their bare arm (77%), which is the right thing to do. While 58% of people took two blood pressure measures each time, which is correct, only 40% used the average of the two blood pressure readings. Very few (15%) measured their blood pressure over several days in both the morning and evening. Only half of the people in our study used a blood pressure device that had been <a href="https://bloodpressuretoolkit.com/what_device_should_i_use">clinically validated</a>. This means the device has been <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.117.10237">tested for accuracy</a> by the manufacturer according to <a href="https://www.iso.org/sectors/health">international standards</a>, not just safety. <h2>Consultation and communication</h2> Regardless of whether or not a doctor had recommended they measure their blood pressure at home, most people (78%) reported their blood pressure readings to their doctor. These findings tell us doctors often use home blood pressure readings to help diagnose and manage high blood pressure. This emphasises how important it is to ensure people measure blood pressure correctly. Many people were measuring their blood pressure a few times a week or month. But most <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4671913/">guidelines</a> recommend blood pressure only needs to be measured at home: every day over a week, every six months; and ideally before you see your doctor and after you start or change blood pressure medication. Measuring blood pressure at home can bring peace of mind, which many study participants described. But measuring your blood pressure too often may create unnecessary stress, potentially leading to higher blood pressure readings. Instead, it’s better to agree with your doctor how often you should measure your blood pressure and to follow the recommended steps each time to make sure your readings are as accurate and useful as possible. <h2>Support for blood pressure measurement</h2> We found few people had received any education or guidance from health-care professionals about how to measure their blood pressure at home. Instead, many study participants looked for information online to help them know what their blood pressure numbers meant and changes they could make to lower their blood pressure. They were less interested in learning how to measure accurately. So we have worked with people who measure and manage their blood pressure at home to create a <a href="https://bloodpressuretoolkit.com/">simple guide</a> to help you choose a blood pressure device, measure your blood pressure accurately, understand your blood pressure readings and take action to control your blood pressure. <hr /> For more information about managing your blood pressure at home, <a href="https://bloodpressuretoolkit.com/">see our resources</a>. You can also check if your blood pressure device has been <a href="https://bloodpressuretoolkit.com/what_device_should_i_use">tested for accuracy</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/244161/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/niamh-chapman-2262829">Niamh Chapman</a>, Senior Research Fellow, Hypertension and Patient Engagement, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/dean-picone-2264237">Dean Picone</a>, Senior Research Fellow, Sydney School of Health Sciences, Faculty of Medicine and Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/eleanor-clapham-2264235">Eleanor Clapham</a>, PhD candidate, School of Health and Medicine, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Mum of four saved by her smartwatch

Ricki-Lee Wynne was gifted a smartwatch from her husband for her 40th birthday and she believes that without it, she wouldn’t be alive today. "There's no doubt that my smartwatch saved my life," she told 9news.com.au. Months prior to receiving the watch, Wynne had been experiencing strange health problems. "I was getting a pain over my shoulder blades and it hurt each time I breathed in," she said. Doctors were confused and Wynne was in and out of hospital having several X-rays, scans and blood tests in an attempt to find the underlying issue. Wynne also had an echocardiogram to test the functioning of her heart, all of which appeared normal. "The doctors were not sure what it was. They thought it could be a low-grade blood cancer," she said. The pain subsided for a little while but soon enough Wynne’s breathing problems returned. "I woke up one day and I couldn't breathe properly. I was just walking into work and I was thinking, 'Gosh, I can't get enough air into my lungs,'" she said. "I couldn't walk from one side of the room to the other without being short of breath. "I went to my GP and had an x-ray done, but nothing showed up.” That’s when Wynne noticed her smartwatch was acting up. "I'd been struggling with my watch for days to try and get the heart rate to show up," she said. The heart rate function of her smartwatch had never been an issue before, but now it was struggling to pick it up. "It was saying you need to change the position to measure a pulse," she said. "My chest was also feeling kind of wobbly for a couple of nights when I went to bed.” Despite her X-ray showing coming up clear, Wynne said she went back to see her GP and told him she was worried something was really wrong. "I just said to him, 'Even my heart rate isn't right, look at my watch,' and I showed it to him.” Wynne’s GP sent her off for an ECG which showed her heart rate had dropped to just 29 beats per minute, a major cause for concern. "As soon as I had the ECG, I had the doctor call me back and say you need to go straight to Box Hill Hospital," she said. "I was told at the hospital that if I hadn't come in I would have just died in my sleep. "I would not have woken up and my heart would have stopped.” Wynne was then fitted with an emergency pacemaker and eventually diagnosed with a rare auto-immune disorder called sarcoidosis, a condition that causes inflammation in different parts of the body, most commonly the lungs. Doctors believe Wynne's Sarcoidosis moved from her lungs to her heart, causing her to become extremely ill. She still has the pacemaker in and combined with medication, her health has improved significantly. It’s safe to say Wynne won’t be taking off her smartwatch any time soon.

Deputy PM tests positive for Covid, Premier and PM monitoring for symptoms

Deputy Prime Minister Barnaby Joyce has tested positive for Covid-19, while Prime Minister Scott Morrison and Premier Dominic Perrottet have been advised to monitor for symptoms. Barnaby Joyce tested positive for the virus after traveling to Washington DC for work relating to the government's plan for new regulations on social media. Speaking with ABC Radio New England, the Deputy PM said he chose to get tested after experiencing mild symptoms. "Look, obviously [I am] very frustrated I'm going to be locked up in a room by myself for 10 days, but that's part of the process," he said. "It's probably developing, I'm probably very much in the early stages — but I'm more worried about being in a room by myself to be honest." Barnaby's positive result comes just hours after Scott Morrison and Dominic Perrottet were told to monitor for Covid symptoms, after the Bathurst 1000 Supercar races were listed as an exposure site. The Prime Minister and NSW Premier were among thousands of people at Mount Panorama for the Great Race on Sunday, where there has been at least three positive cases. “I was informed early this afternoon that I’m not a close contact,” Mr Perrottet said on Wednesday. “But obviously, for those people who have been to Bathurst and have symptoms, they need to get tested. And, if there is advice from NSW Health, then they need to follow that advice.” The McPhillamy Park Campground, The Paddock Campground, Harris Park, Merchandise Alley, National Motor Racing Museum, and Inside Chase viewing area have all been listed as venues of concern. Barnaby Joyce, Scott Morrison and Dominic Perrottet are all fully vaccinated against Covid-19. Image credits: Getty Images

A smart way to monitor melanoma

<div> <div class="copy"> Monitoring for a recurrent <a rel="noreferrer noopener" href="https://cosmosmagazine.com/science/biology/inside-a-melanoma-cell/" target="_blank">melanoma </a>may be as simple as using a smartphone, according to Australian and New Zealand <a rel="noreferrer noopener" href="https://doi.org/10.1001/jamadermatol.2021.4704" target="_blank">research,</a> published in JAMA Dermatology. This may provide feasible, patient-led follow-up care to monitor whether melanomas return. “People who have had one melanoma have an increased risk of developing an additional one, especially during the first few years,” says Professor Monika Janda of the University of Queensland, who was involved in the study. <h2>Pilot study shows promise</h2> A small pilot study of 100 patients found that using a skin-checker app and a magnifying device attached to a smartphone provided a safe way to monitor signs of cancer coming back after melanoma is removed. “We gave patients special devices for their mobile phones, which allows them to take really precise photographs of skin lesions,” says Janda. “These are all patients who have had melanoma before.” This group used the smartphone app at home, and they found more signs of melanoma compared to people who went in for hospital surveillance “We found that there were quite a number of additional signs found by people themselves at home, which was really interesting,” says Janda. <h2>Less travel for melanoma patients</h2> Normally, patients need to travel to their doctor or hospitals for surveillance, which can be difficult and time-consuming. The smartphone method provides a feasible alternative that could be conducted at home. “It could save some of the current visits to the doctor that people do regularly after they’ve had a melanoma,” says Janda, “That could be particularly beneficial for people who live far away from their treatment centre and have to undertake extensive travel to reach them.” As this was a pilot study, a larger, randomised clinical trial is required to see how this monitoring would relate to more patients in the long term. “It’s a pilot study, so it’s not yet definite. But we’re currently undertaking a bigger study,” says Janda.

High-profile crimes: The problem with electronic monitoring bracelets

The man arrested after a <a href="https://www.abc.net.au/news/2019-06-04/darwin-shooting-people-police-arrest-gunman/11179136">deadly gun attack in Darwin</a> recently is <a href="https://www.theguardian.com/australia-news/2019/jun/04/police-say-they-have-reports-of-up-to-four-people-dead-in-darwin-shooting">reported</a> to have been on parole and wearing an electronic monitoring bracelet. This leads to the same reaction we see following any high-profile crime. How could such a thing happen? People may speculate that the criminal justice agencies involved have somehow dropped the ball. The offender was on their radar, after all. While this finger-pointing may serve a cathartic function, it is important we also question our expectations before assuming a failure occurred. We need to understand what electronic monitoring intends to achieve, how it works, and what are its capabilities and limitations. Electronic tagging In the context of the corrections system, electronic monitoring refers to the tagging of a person as a form of surveillance, usually in the form of a GPS-enabled ankle bracelet. <a href="https://aic.gov.au/publications/tandi/tandi254">In Australia</a>, each state and territory uses electronic monitoring differently, guided by their own legislative frameworks. Practices vary considerably between jurisdictions. For example, in some places, certain offenders are targeted (high-risk recidivists, those who repeatedly reoffend, for example). In others, specific types of offences are the focus (such as child sex offences). The application of electronic monitoring even differs between offenders, as the supervising agency uses it for reasons specific to each person. A police department might use electronic monitoring to ensure a domestic violence perpetrator does not visit the victim before a trial. A probation officer might require an offender to wear a bracelet for 12 months to ensure they are attending treatment and meeting their curfew. A parole officer could place the GPS tracking condition on an offender for the first three months following release from prison to better understand how the parolee spends his or her time. Each of these experiences will be quite different, as each is intended to fulfil a unique aim. Ordinarily, electronic monitoring is used as a tool of incapacitation and deterrence. In the first instance, an offender may be told to follow a particular rule – for example, to be home by 8pm, to stay away from the victim, to attend a treatment program, or not to go within 1km of a school. Electronic monitoring allows authorities to monitor the person’s compliance with such a condition. In the latter instance, an offender may be deterred from certain behaviour if they believe their actions are likely to be detected through electronic monitoring. Monitoring actions When an offender is subject to electronic monitoring, a computer database is updated with information about the rules he or she has been instructed to follow. Each jurisdiction and each agency may have their own database, so where the offender appears in the database will depend on who is supervising the electronic monitoring order. The database is then monitored by enforcement authorities, although this is sometimes outsourced to private providers or overseas companies. While the data is generally sent from the offender’s GPS device to the monitoring agency in real time, there can be delays in how long it takes for that information to be passed to police or corrective services. What occurs when an offender breaches one of the rules and a computer alert is generated depends on factors such as legislation and the priority of a case influencing the response. The database includes information about what to do in the event of specific kinds of breaches with specific offenders. In some cases, an alarm on the device may go off or, very rarely, the police may be immediately notified. Most often, for routine cases and ordinary breaches, the monitoring agency will notify the offender’s supervisor (such as a parole officer or a local police department), who will then determine how to proceed. There may be a lag of several days during this process. For example, if a low-risk offender misses their home curfew on Friday night (as determined by the GPS bracelet), the parole officer will not receive notification of this breach until Monday morning. The pros and cons of tagging There are a range of <a href="https://journals.sagepub.com/doi/pdf/10.1177/2066220317697658" title="Electronic monitoring: The experience in Australia">benefits and disadvantages</a> to the electronic monitoring of offenders. It can be effective in holding offenders accountable, protecting victims and enhancing community safety and preventing crimes. These come with important cost savings, particularly when offenders can be safety monitored in the community in lieu of imprisonment or as a mechanism of early release from prison. But some of the downfalls are that offenders can tamper with their devices, and there can be GPS dead zones – particularly in a geographically vast country such as Australia. There may also be human error in using the systems, such as improper monitoring or unreasonable decision-making after an alert. Yet collectively, the research evidence highlights that electronic monitoring can be an effective tool for discouraging recidivism. But it is only that: a tool. The most effective practices for <a href="https://au.sagepub.com/en-gb/oce/environmental-corrections/book248663" title="Environmental Corrections: A New Paradigm for Supervising Offenders in the Community">supervising offenders in the community</a> include those that identify and reduce a person’s risks for continued criminal behaviour. Electronic monitoring will be most effective when it is used to support supervision that limits a person’s access to chances to commit crime. Such supervision should help them redesign their routines so that any risky settings are avoided and are replaced with more positive influences. Thus, rather than simply giving offenders a long list of rules for what not to do, effective probation and parole strategies help offenders lead productive lives. More broadly, it is imperative that correctional authorities provide rehabilitative interventions that address the underlying factors that contribute toward a person’s criminal behaviour. The <a href="https://nicic.gov/implementing-evidence-based-practice-community-corrections-principles-effective-intervention">most effective approaches</a> use cognitive-behavioural techniques to give offenders skills that encourage good decision-making. Yet electronic monitoring cannot “fix” an offender’s impulsivity, lack of empathy, or any other underlying crime-conducive traits. Thus we should not confuse a technological aid with meaningful treatment. Written by Lacey Schaefer.

Most over-65s comfortable with at-home monitoring

The term “nanny state” gets thrown around an awful lot these days, but when it comes to ageing and health, being closely watched mightn’t be such a bad thing. A survey of 1,200 Australians found that 91 per cent of people over 65 and 90 per cent aged 50 to 64 would feel comfortable having their health monitored thanks to trackers around the home. The report, conducted by HCF, found that most Australians – particularly older generations – had a positive attitude towards technology being used in health and aged care. In fact, 85 per cent of over-65s reported they would be confident if artificial intelligence (AI) was used to help diagnose medical problems. However, 57 per cent did admit to concerns about the privacy of their records and the fact that AI lack human intuition and empathy. “It’s clear that Australians can see the benefit of technological advancements in health, particularly where it can be used to prevent disease and improve patient care,” HCF Managing Director Shaun Larkin said. “However, it seems we are also torn between the perceived positives and the potential limitations of removing the human element.” HCF’s findings come at a time in Australian healthcare where more and more aged care experts are embracing the idea of AI. In fact, <a href="http://www.oversixty.com.au/health/caring/2017/03/robot-helps-people-with-dementia/">earlier this week</a> we reported on the revolutionary robot Matilda, which has been found to improve the quality of life in hundreds of dementia patients. “It’s easy to get excited about technology that can help save lives and potentially revolutionise patient care,” Larkin added. “At the same time, we need to be aware of the implications of change – from the true cost of technological advancements to other ethical and personal considerations.” Are you comfortable with the idea of AI around our hospitals, doctor’s practices and even our homes?

Five-foot goanna found in Australian backyard

Eric Holland, from Thurgoona in New South Wales, Australia, got the surprise of his life earlier this week when he came across a monster lizard in his backyard. "I was just doing a repair job in my shed when I opened the door and I saw this huge thing run across the ground and out of sight," Mr Holland said. "I went inside after I saw it in the backyard and heard a banging noise coming from the side of the house," "When I went outside I saw him on the side of the house with his tail hitting the drain pipe." Having never seen anything like it in the 18 years he has lived in his home, Mr Holland reveals, "It was a big surprise really. I sometimes get blue tongues and lizards in the backyard but never anything quite like this." The goanna quickly left Mr Holland's property and he has not sighted the reptile since. The reptile in question is a lace monitor, also known as lace goannas, and can grow to around two-metres in length and weigh up to 20 kilograms. <a href="/news/news/2015/12/baby-goat-learns-to-hop-video/"> </a>

Specially designed high-tech apartment to monitor health of elderly

Engineers at the University of Texas at Arlington have teamed up with Christian Care Senior Living Communities to design and build a “smart care” apartment with the aim of improving the lives, safety and overall health of its residents. Built in an 86 square-metre apartment donated by Christian Care, the new design was unveiled in May as a prototype it’s hoped will change the lives of seniors, as well as people with disabilities who wish to remain independent. How will it help? With in-built state-of-the-art technology and clever design, of course. The project received federal funding from the US Government to the tune of US$600,000 over five years, allowing extensive research in a collaborative effort involving faculty from the UT Arlington College of Nursing and Health Innovation and the College of Engineering. This development period has led to the following technologies being incorporated into the design: <ul> <li>Under-floor sensors that allow researchers to measure and evaluate changes in walking gait, balance and weight. It is hoped that this feature will help give early indication of illness or injury.</li> <li>A lift chair to help residents stand.</li> <li>LG brand appliances in the kitchen that communicate with each other.</li> <li>Exercise equipment like a recumbent bike and an interactive X-Box Kinect system.</li> <li>A camera embedded in the bathroom mirror to monitor day-to-day heart rate, skin colour, and facial expressions. Changes in these features can be revealing about aspects of overall health, as well as the amount oxygen present in the blood.</li> <li>A special mug that interacts with the coffee table to record blood pressure readings.</li> </ul> Now that the design has been unveiled, the search is on for a couple within the Lakewood Village Senior Living Community, who will live in the apartment for at least 12 months so researchers can study the effectiveness of the design, and receive feedback on the usability.
