Abstract
Patient pressure monitoring systems require constant monitoring and adjustment by patient care specialists because of erroneous indications of changes in blood pressure readings which occur is such systems. The changes are due to errors produced by the sensing system caused by patient movement with respect to the pressure sensor. Such erroneous changes are eliminated by the addition of a second fluid path which is maintained at atmospheric pressure and controllably is connected to the prime fluid path to normalize any change in pressure in the prime path due to changes in relative positions of the sensor and the patient.
