Patent number: 8465292Abstract: Embodiments of the present invention are directed toward a system and method of determining real time chest compression depth of a CPR patient or manikin from acceleration and a reference signal, such as force. In one embodiment, an acceleration signal is filtered and integrated to determine a raw depth signal. A force signal is adjusted to having a similar amplitude, phase, and shape as the raw depth signal. The force signal is filtered. The adjusted force signal is subtracted from the filtered force signal to obtain a compensation signal. The chest compression depth is obtained by adding the raw depth signal to the compensation signal.Type: GrantFiled: February 15, 2008Date of Patent: June 18, 2013Assignee: Laerdal Medical ASInventors: Jon Nysæther, Joar Eilevstjønn

Publication number: 20100036266Abstract: 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.Type: ApplicationFiled: July 31, 2009Publication date: February 11, 2010Applicant: Laerdal Medical ASInventors: Helge Myklebust, Joar Eilevstjonn, Jon Nysaether
