Abstract
Embodiments are directed to a device and method for detecting heart beats and/or monitoring ventilation and/or respiration of a patient using air pressure. In one embodiment, a monitoring device comprises a gas duct and at least one pressure sensor configured to measure pressure in the duct. The duct may be in fluid communication with a patients airways. Based on the sensed pressure, a heart beat of the patient may be detected. In another embodiment, a flow rate of the air expired from the patient may be calculated based on the pressure and a known flow resistance.
