Abstract
A blood pressure measuring apparatus displays that pressurization of a pressure cuff affixed to a patient is inadquate when elapsed time from the start of cuff depressurization to the detection of an initial sound of blood flow through the patient's blood vessel is shorter than a time interval between adjacent blood flow sounds, which interval approximately coincides with the patient's pulse interval.
