Hypertension is called a "silent killer". Most people with hypertension are unaware of the problem because it may have no warning signs or symptoms. For this reason, it is essential that blood pressure is measured regularly.
An estimated 1.28 billion adults aged 30-79 years worldwide have hypertension, most (two-thirds) living in low- and middle-income countries
Hypertension is one of the most significant risk factors for cardiovascular diseases (CVDs).
Blood pressure is written as two numbers. The first (systolic) number represents the pressure in blood vessels when the heart contracts or beats. The second (diastolic) number represents the pressure in the vessels when the heart rests between beats.
Hypertension is diagnosed if, when the systolic blood pressure readings are ≥140 mmHg and/or the diastolic blood pressure readings are ≥90 mmHg same for two continuous days.
Current BP measurements are on the basis of traditional BP cuff approaches which need to be inflated and deflated. The traditional cuff-based BP monitoring takes 2-3min for BP measurement being insufficient for continuous monitoring.
Invasive blood pressure monitoring: Invasive (intra-arterial) blood pressure (IBP) monitoring is a technique used in ICUs. It's a direct measuring technique that involves inserting a cannula needle inside a suitable artery. This method has many advantages and drawbacks. The major drawback is the penetration of blood vessels, which might cause infection and discomfort to the patient if not handled properly.
Most of the problems have to do with size, position, inflation, frequency, and tightness of the cuff majorly seen in automatic BP monitoring during emergency and surgery environment
In addition, medical issues like injuries, swelling, nerve damage, capillaries bursting, and are all part of blood pressure cuff complications.
To overcome the disadvantages of traditional BP measurements based on cuff occlusion, this paper outlines an algorithm built using ECG and SpO2 physiological signals. This solution provides easy-to-use devices, pocket-sized BP monitoring devices without the need for a pressure cuff for quick measurement and maintaining high accuracy.
