Abstract
A monitoring device and method for finding the critical opening pressure, the critical closing pressure and the over distention pressure of the lungs by first, delivering pulses of gas to the lungs without allowing the gas to escape, and then, allowing the gas to escape, all the while, monitoring the resulting pressure change. By looking at a simple pressure-over-time depiction of these pressure changes, the critical opening pressure, the critical closing pressure and the over distention pressure can be determined by observing the overall pressure change and the incremental pressure changes.
