Blood pressure is the blood pressure on the blood vessel walls. It is one of our primary vital signs and one of the most frequently controlled factors in all kinds of medical check-ups, triage before hospital admission, etc., and is a particularly informative parameter of a patient’s overall situation. Blood pressure differs widely from person to person, is subject to circadian rhythms, and is influenced by stress, dietary variables, consumption of medication, and illness. It is a metric that is widely accepted and from a clinical point of perspective is crucial. Furthermore, high blood pressure raises the danger of heart attack and stroke, while reduced blood pressure is considered favourable.
The main component in the shift to preventive health technologies, precise and continuous blood pressure surveillance is commonly seen as a basic parameter in terms of health surveillance. It is helpful to know a patient’s heart rate at a moment when more and more individuals are using wearables such as the Apple Watch, which provide constant monitoring through photoplethysmography or even a fairly secure electrocardiogram, but it is more essential to be prepared to mix this data with other parameters. The parameter they all claim is most helpful for diagnoses, apart from heart rhythm, is blood pressure, talking to cardiologists.
Now, a team of University of Toronto scientists have developed a manner to correctly evaluate blood stress using a smartphone camera and a selfie-like operation. The test is performed by transdermal optical scanning: the light produced by the smartphone camera bounces at distinct rates off the proteins close the skin surface, enabling for a minimal assessment of modifications in haemoglobin, which offers precise identification of blood pressure with a battery of 900 pictures made in 30 seconds.
Whether the method works for all skin types is not yet evident, which is essential considering the greater incidence of high blood pressure and related mortality in black people, but the concept has capacity, without a doubt, because it is not hard to devote thirty seconds a day to get one’s blood pressure and could assist identify countless health issues soon. Moreover, regardless of whether something is identified or not, the gathered data could supply countless research if distributed and add to the development of medical science as a whole.
Wearables of different kinds that record our vital parameters, beds that control our sleep, easy but accurate analytics that substitute controls that we used to perform once a year or less, and artificial intelligence to process all these information are just some of the components that will radically change healthcare in the years to come, depending on a proactive strategy rather than sleeping until we get ill. To see a real change in the mentality of health professionals, this sort of development and its opportunities, both for research and medical exercise, must be implemented into university programs as quickly as feasible.
