ABSTRACT:
An apparatus and method for non-invasive, noise insensitive blood pressure determination which is useful in a battlefield or emergency vehicle environment. The system features an occlusion bladder and a sensing bladder both adapted to fit over the limb of a patient. The pressure in the occlusion bladder is raised to a value which prevents flow and is then gradually decreased. The pressure in both bladders is monitored. When the pressure in the sensing bladder reaches a minimum value, the pressure in the occlusion bladder is equal to the systolic pressure. The first, second, and third time derivatives of the pressure in the sensing bladder are monitored. The first derivative is useful in identifying the minimum in the pressure in the sensing bladder. When the third time derivative of the pressure in the sensing bladder passes through zero, the pressure in the occlusion bladder is equivalent to the mean arterial pressure. The diastolic pressure can be calculated from the values of the systolic and mean arterial pressures.
