A blood pressure meter is a device used to measure blood pressure, composed of an inflatable cuff to restrict blood flow, and measure the pressure. It is always used in conjunction with a means to determine at what pressure blood flow is just starting, and at what pressure it is unimpeded.
Blood pressure meter, using oscillometric measurements and electronic calculation rather than auscultation. They may use manual or automatic inflation. These are electronic, easy to operate without training by anybody, and can be used in noisyenvironments. They measure systolic and diastolic pressures by oscillometric detection, using a piezoelectric pressure sensor and electronic components including a buzzer. They do not measure systolic and diastolic pressures directly, but calculate them from the mean pressure and empirical oscillometric parameters. Most instruments also display pulse rate.
