<p>A blood pressure system which cycles through an inflation cycle and a deflation cycle during which systolic and diastolic pressure in a patient is automatically measured. The blood pressure system basically comprises a pressure cuff system for accomplishing occlusion and the subsequent opening of an artery in a patient being monitored, and an electrical system for controlling the pressure cuff system and for displaying the systolic and diastolic measurements. In order to automatically carry out the inflation and deflation cycle of the blood pressure system, a dedicated controller is employed. A microphone, contained within the blood pressure cuff produces an electrical signal indicative of pulsatile activity within the artery. A K-sound detector receives the signal and relays information to the dedicated controller. In the blood pressure system, K-sound detection continually takes place during both the inflation and deflation cycles of the instrument.</p> |
