Problems solved by technology

[0008] A major disadvantage of such devices is that they add extra equipment to all that is required by first responders, thereby delaying the initiation of cardiac massage during CPR when speed is a critical factor in determining a patient's survival
[0012] Today, it has been found in practice that with this type of equipment, the presence of CCs is not always correctly detected when the gas is just being delivered to the patient, thus falsifying the estimate of the frequency of said CCs and making the first First responders or other members of the rescue crew delivering wrong information

Embodiment Construction

[0072] figure 1 An exemplary embodiment of a ventilation aid or medical ventilator 1 according to the invention is depicted.

[0073] The ventilator 1 includes a motorized micro-blower 4 that delivers a flow of breathing aids (typically air or oxygen-enriched air) into a ventilation circuit 2 (also referred to as a patient circuit) comprising One or more gas channels or lines, such as a breathing mask or a cannula, fluidly connect the ventilator 1 to the airway of the patient 20 .

[0074] Air source 4 (typically a motorized micro-blower, also known as a turbine or compressor) is controlled by a control device to deliver respiratory airflow and intermittently generate pressure levels (Ph, Pb) for preset durations (Dh, Db ).

[0075] The motorized microblower 4 is equipped with an electric motor driving an impeller for generating an air flow which is then conveyed upstream of the patient circuit formed by one or more gas passages (such as pipes, etc.), said one or more A plu...

Abstract

The invention relates to a respiratory assistance apparatus (1) usable by a first responder, such as a doctor from the emergency ambulance service, a fire fighter, a nurse or the like, when this first responder is performing cardiac massage on an individual (20) in cardiopulmonary arrest, in order to ventilate the said individual while he or she is being subjected to chest compressions. According to the invention, the respiratory assistance apparatus (1) comprises signal processing means designed to supply the display means with a corrected frequency value (Fc) corresponding to the frequency value (F) determined immediately before the start of a time of duration (Dh, Db) considered, when the signal processing means do not detect a chest compression (CC) for part of the said duration (Dh, Db) considered.

Description

technical field [0001] The present invention relates to an artificial ventilation device or apparatus (also known as a breathing or ventilatory aid), and more particularly to a device or apparatus for first responders—such as doctors in ambulance services, firefighters, nurses, etc.— A breathing assistance apparatus that can be used by the first responder when performing cardiac massage on an individual (ie, patient) in cardiac arrest to ventilate the individual while he or she is undergoing chest compressions. Background technique [0002] Certain types of breathing aids or ventilators are fitted to emergency vehicles, especially in response to road traffic accidents or when urgent medical assistance is required, for example in the case of a heart attack. [0003] Therefore, in the case of a heart attack, combining artificial respiration / mechanical ventilation with cardiac massage for an individual in cardiac arrest—that is, performing cardiopulmonary resuscitation (CPR)—is...
