Project Overview

Blood pressure is a critical measurement to assess, for health professionals are able to determine an individual's vascular health based upon their systolic and diastolic blood pressure. Presently, the most commonly used instrument to measure blood pressure is a sphygmomanometer, which measures blood pressure by attaching an inflatable cuff around the patients upper arm and using a bulb to manually inflate the cuff, which then collapses and releases the brachial artery. However, this instrument must be used in conjunction with a stethoscope in order for the clinician to be able to sense when the brachial artery is initially released (systolic) and when the pressure against the arterial wall can no longer be sensed (diastolic). This blood pressure is then measured on a mercury manometer. Electrical sphygmomanometers are also commonly used to measure a patient's blood pressure; however, both instruments are rather bulky and are ineffective in providing a healthcare professional with regular updates on a patients instantaneous blood pressure. Also, this method is not feasible in loud environments or when the patient is moving. Therefore, the scope of our project is to be able to create a blood pressure sensor that can accurately and regularly measure a patient’s blood pressure while reducing the effective size of the product, prevent the device from withdrawing an excessive quantity of battery power, and be used in loud or moving situations. This design would enable healthcare professionals to be able to acquire a patient’s blood pressure instantly and frequently without having to work around a sphygmomanometer, which would be crucial for emergency medical transports of patients with massive blood loss (hypotension) or cardiac arrest/ stroke (hypertension).
