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: 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 method of controlling a respiratory assistance apparatus delivering a flow of gas, particularly a flow of air, comprising the steps of measuring at least one parameter indicative of said flow of gas; converting said at least one parameter indicative of said flow of gas into at least one signal indicative of said flow of gas; processing said 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 said 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 said control method.
