Abstract
A portable physiological pressure monitoring device adapted for being attached to a body part of a patient in which the compartment pressure is to be continuously monitored. The device includes an alarm for indicating when a predetermined maximum pressure limit is exceeded or when a predetermined minimum pressure is not maintained for a certain period of time. The pressure device also includes a hydrophobic filter which separates a catheter and the sensing components of the pressure device for providing sterile operation. A warning also sounds when a battery falls below a given voltage level. Finally, the pressure monitoring device also includes apparatus for measuring nerve conduction velocity and action potential to facilitate better diagnosis and monitoring of compartment syndrome.
