Abstract: Disclosed is a method of controlling a respiratory assistance apparatus delivering a flow of gas, particularly a flow of air, having the steps of measuring at least one parameter indicative of the flow of gas; converting at least one parameter indicative of the flow of gas into at least one signal indicative of the flow of gas; processing at least one signal indicative of the flow of gas in order therefrom to deduce at least one item of information relating to cardiac massage being performed on a patient in cardiac arrest; on the basis of at least one deduced item of information, automatically selecting a given ventilation mode from among a number of stored ventilation modes, and controlling the respiratory assistance apparatus by applying the selected ventilation mode. Respiratory assistance apparatus capable of implementing this control method.

Abstract: The invention relates to a respiratory assistance apparatus (1) such as a medical ventilator, comprising a gas circuit (2, 16) with at least one inhalation branch (2) able to carry a respiratory gas intended to be administered to a patient under cardiac arrest during cardio pulmonary resuscitation; measurement means (6) suited to and designed for measuring at least one parameter indicative of said flow of gas and converting said at least one parameter indicative of said flow of gas into at least one signal indicative of said flow of gas; and a signal processing and control means (5, 8) suited to and designed for processing said at least one signal indicative of the flow of gas supplied by the measurement means (6) and deducing from said at least one signal indicative of the flow of gas information relating to the phases of compression and relaxation of a cardiac massage on the patient under cardiac arrest and controlling the motorised micro blower (40) and exhalation valve (19) accordingly in response to the

Abstract: A respiratory assistance apparatus (1) for delivering a flow of gas to a patient (P) comprises a gas delivery conduit (2) for conveying a flow of gas, measuring means (6) designed to measure at least one parameter representative of the flow of gas and to supply at least one signal corresponding to said parameter, signal-processing means (8) designed to process said signal coming from the measuring means and to deduce from said signal at least one item of information relating to performance and/or discontinued performance of chest contractions (CT), calculating means designed to calculate at least one duration of discontinuation or absence of chest contractions (tNCT), and storage means (12) configured to register said duration of discontinuation or absence of chest contractions.

Abstract: The invention relates to a respiratory-aid apparatus (1) capable of supplying a stream of gas to a patient (P), comprising a gas-transport pipe (2) for transporting a stream of gas, such as air; measurement means (6) designed to measure at least one parameter representing the stream of gas and to supply at least one signal corresponding to said at least one parameter representing said stream of gas, for example the gas flow rate or pressure; signal-processing means (8) designed to process said at least one signal from the measurement means (6) and to deduce therefrom at least one piece of information (I1, I2, I3) characterising a cardiac massage performed on a patient; and display means (7) designed to display said at least one piece of information (I1, I2, I3) characterising a cardiac massage from the signal-processing means (8).

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.
