Abstract
Pressure measuring lumen allows a coarse pressure value of a subject to be read. A liquid filled lumen is allowed to pressure communicate with an atmosphere adjacent to a patient, through the use of a membrane and an atomosphere-opening lumen. A liquid pressure value read from the liquid filled lumen is used to adjust the pressure value to compensate for pressure changes induced by a positional change of the subject.
