A flow sensor system for ventilation treatment comprises a flow conduit configured to allow gas flow between a first region and a second region, the flow conduit defining a lumen for the gas flow; a flow restrictor disposed within the lumen of the flow conduit between the first region and the second region; a first absolute pressure sensor disposed adjacent to the first region of the flow conduit and configured to measure a pressure of the gas flow at the first region of the flow conduit; and a second absolute pressure sensor disposed adjacent to the second region of the flow conduit and configured to measure pressure of the gas flow at the second region of the flow conduit.

A chest compression device with a chest compression belt assembly including guards and sensors operable with a control system to control operation of the system depending on detection of proper installation of the guards.

A method for performing cardiopulmonary resuscitation (CPR) includes elevating the head, heart and shoulders of an individual from a starting elevation angle to a final elevation angle greater than zero degrees relative to horizontal while performing CPR by repeatedly compressing the chest. The method includes elevating the brain within a time period selected to be slow enough to permit a sufficient amount of blood to flow to the brain throughout the elevation time period. The method also includes regulating the intrathoracic pressure of the individual while performing CPR. The performance of chest compressions is stopped and after stopping the performance of chest compressions, the head, heart, and shoulders are promptly from the final elevation angle within a timeframe selected to prevent significant drainage of blood from the brain until the head, heart and shoulders are lowered.

A portable medical device having improved ECG trace display and reporting. Embodiments implement features to ameliorate artifacts created by virtue of attempting to eliminate compression artifacts due to mechanical compression devices. Other embodiments additionally implement features to seek to detect the occurrence of ROSC while chest compressions are ongoing.

A CPR device having a base member configured to be placed underneath a patient, a chest compression mechanism configured to deliver CPR chest compressions to the patient, a support leg configured to support the chest compression mechanism at a distance from the base member, a clamp mechanism coupled to the support leg, and a release mechanism coupled to the support leg and the clamp mechanism. The clamp mechanism is configured to attach the support leg to a lock component of the base member in a latch-closed configuration and to release the support leg from the lock component in a latch-open configuration. The clamp mechanism is further configured to transition from the latch-closed configuration to the latch-open configuration when the lock component of the base member impacts an external portion of the clamp mechanism without the release mechanism being pulled away from the base member.

An automated resuscitation system is provided, which can improve the outcome of patients suffering ventricular fibrillation or the ventricular tachycardia variants of cardiac arrest. This outcome can be achieved by a device that integrates automatic mechanical or pneumatic capability with electrical countershock capability such that the probability of defibrillation or cardioversion with return of spontaneous circulation is increased.

A method for performing cardiopulmonary resuscitation (CPR) includes elevating the heart of an individual to a first height relative to a lower body of the individual. The lower body may be in a substantially horizontal plane. The method may also include elevating the head of the individual to a second height relative to the lower body of the individual. The second height may be greater than the first height. The method may further include performing one or more of a type of CPR or a type of intrathoracic pressure regulation while elevating the heart and the head. The first height and the second height may be determined based on one or both of the type of CPR or the type of intrathoracic pressure regulation.
