青岛希尼尔翻译公司（www.sinosenior.com）2016年3月5日了解到：　A best-selling blood pressure app gives false readings almost 80 per cent of the time, according to a new study.
　　据一项新的研究，一款畅销血压计app的读数错误率高达80%。
　　The app, called Instant Blood Pressure, purports to accurately measure blood pressure by placing a smartphone on a person’s chest with a finger over the built-in camera lens.
　　这款app名为即时血压，通过在人的胸口上放置智能手机并且把手指放在内置摄像头上，它可以准确地测量血压。
　　However, the app is potentially putting users’ health at risk by missing high blood pressure in nearly eight out of ten people, according to scientists from John Hopkins University.
　　然而，据约翰霍普金斯大学的科学家称，这款app错过了十个人里将近八个人的高血压，可能将使用者的健康置于危险之中。
　　The app was first released in June 2014 - and spent 156 days in the top 50 best-selling charts, with at least 950 purchases a day.
　　2014年6月，这款app首次发布，连续156天占据销量榜前50位，每天至少售出950个。
　　In total, it was downloaded more than 100,000 times, the scientists said.
　　科学家称，这款app总计下载量超过十万次。
　　Study co-author Dr Timothy Plante, of Johns Hopkins, said: ’Because this app does such a terrible job measuring blood pressure, it could lead to irreparable harm by masking the true risk of heart attacks and strokes in people who rely on the accuracy of this information.’
　　约翰霍普金斯大学研究合著者Timothy Plante博士说：“因为这款app承担着测量血压的艰巨任务，掩盖心脏病和中风的真实风险，将会使得依赖相关准确信息的人承受不可挽回的伤害。”
　　The scientists examined 85 participants for the study.
　　科学家检测了85名参与者。
　　More than half of the participants had self-reported hypertension - and 91 per cent reported taking anti-hypertensive medications.
　　过半的人都有高血压，91%的人服用抗高血压药品。
　　Study co-author Dr Seth Martin said that the scientists were ’skeptical that even very talented people could design an app that could accurately measure blood pressure’.
　　研究合著者 Seth Martin博士说，科学家质疑，即便是非常有才能的人，也不一定能够设计一款精确测量血压的app。
　　He added: ’Because of the absence of any rigorous scientific testing, there was no evidence that it worked or didn’t work.’
　　他补充道：“因为缺乏任何严格的科学测试，不能证明它是否可行。”
　　Each of the study participants had his or her resting blood pressure measured twice through a reliable automated blood pressure monitor commonly used in research studies to avoid measure variation or error.
　　为了避免测量偏差或者错误，实验采用研究中通常使用的可信赖的自动血压检测器，每个参与者在休息状态下测量了两次血压。
　　They also used the app to measure their own blood pressure twice on the same day.The study found that blood pressures measurements from the app were ’overwhelmingly inaccurate’.
　　同一天，他们还使用app测量了两次自己的血压。研究发现，app测量的血压绝对不准确。
　　Close to 80 per cent of those with clinically high blood pressure showed as having normal blood pressure with the app.
　　通过这款app，近80%的医学确诊高血压患者显示血压正常。
　　The scientists noted that it’s unclear how the app arrives at a blood pressure number.They suggest, in the study published in the journal JAMA Internal Medicine, that the app doesn’t attempt to measure true blood pressure.
　　科学家强调，目前并不清楚app是怎样记录血压数据的。在《美国医学会杂志——内科学》上发布的研究中，他们暗示，这款app不能正确测量血压。
　　Instead, it gives a population-derived estimate based on the user’s age, height, weight, sex and heart rate, they said.
　　他们还说，这款app基于使用者的年龄、体重、身高、性别和心跳数提供人口来源估计。
　　The app cost roughly $4.99 (?3.50) to download - but was withdrawn in July 2015 for unexplained reasons.
　　这款app售价约为4.99美金，但是2015年7月，却原因不明地下线了。
