What is the function of a Doppler blood pressure monitor?

A Doppler blood pressure monitor utilizes ultrasound waves to detect blood flow and is primarily used to measure systolic blood pressure. It does this by reflecting sound waves off moving blood cells, which allows for the determination of the point at which blood flow begins to return after occlusion. This point corresponds to the systolic pressure, which is the pressure in the arteries when the heart beats.

While the option chosen focuses solely on systolic pressure, it's important to understand that Doppler monitors are not typically used for measuring diastolic pressure. This is due to limitations in the method; the diastolic pressure often cannot be accurately determined with this type of device. Therefore, while the monitor is effective at measuring systolic pressure, it does not provide a reliable measurement of diastolic pressure or any information regarding heart rhythm or respiratory rate.
