Blood Pressure Meter. A blood pressure meter or sphygmomanometer is a device that is used to measure blood pressure. The meter is used with an inflatable cuff for restricting blood flow and a pump to inflate the cuff. Digital blood pressure meters typically measure both systolic and diastolic pressures by an oscillometric detection method
Non Invasive Blood Pressure Monitoring Tutorial 2 pressure that occludes the artery. Even when the artery is occluded the pumping of the heart against the artery can cause small pressure pulses in the cuff baseline pressure. The monitor lowers cuff pressure at a controlled rate. As the cuff pressure goes down blood starts to flow thru the artery.
For measuring blood pressure a blood pressure cuff is placed around the patient’s non method which senses pressure waves in the artery when occluded by pressure in the cuff. Measurement of the frequency of the pressure waves enables heart rate to also be measured. The pulse oximetry function non invasively 2 sensor placed on the
The radial artery is never fully occluded so the method can provide beat to beat blood pressure measures.
