The present invention relates to a method and a respiration device having a respiration unit for generating an airflow for the respiration and having a monitoring unit. The monitoring unit is used to detect a respiration parameter and to classify events in the respiration on the basis of monitoring of the respiration parameter. In this case, the monitoring unit is configured to carry out an event analysis to recognize an occurrence, which is characteristic for Cheyne-Stokes respiration, of chronologically successive events and for this purpose to ascertain the period length thereof and to compare them to one another and to register the presence of Cheyne-Stokes respiration when the compared period lengths each deviate by less than 40% from one another.

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.

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). The signal-processing means (8) are preferably capable of determining information representing the work (W.sub.V, W.sub.T) provided by the massage or pressure and/or flow rate amplitudes resulting from the massage. The invention also relates to a monitoring method capable of being implemented by such a respiratory-aid apparatus (1).

The present system (10) comprises a subject interface (22), a segmenter (12), a loosener (14), sensors (18), and computer processors (28). The segmenter is configured to selectively control gas flow through the subject interface to provide high amplitude pressure oscillations (44) during exhalation such that the high amplitude pressure oscillations aid cough productivity in the subject. The loosener controls gas flow through the subject interface to provide low amplitude pressure oscillations (43, 63) during inhalation (48, 68) and exhalation (49) such that the low amplitude pressure oscillations loosen respiratory secretions. The computer processors detect trigger events based on the output signals such that the one or more trigger events include a loosening trigger event and a segmenting trigger event (66); and responsive to detecting the loosening trigger event, control the loosener to provide the low amplitude pressure oscillations, and, responsive to detecting the segmenting trigger event, control the segmenter to provide the high amplitude pressure oscillations.

In a medical ventilator system, a ventilator (10) delivers ventilation to a ventilated patient (12). Sensors (24, 26) acquire airway pressure and air flow data for the ventilated patient. A probabilistic estimator module (40) estimates respiratory parameters of the ventilated patient by fitting a respiration system model (50) to a data set comprising the acquired airway pressure and air flow data using probabilistic analysis, such as Bayesian analysis, in which the respiratory parameters are represented as random variables. A display component (22) displays the estimated respiratory parameters of the ventilated patient along with confidence or uncertainty data comprising or derived from probability density functions for the random variables representing the estimated respiratory parameters.

A capnography system (100, 400), comprising: a controller (110, 410) configured to obtain a sample gas flow from a physical interface (107) for a patient (101); determine a change in a characteristic of the sample gas flow during a sampling time interval; determine whether the change in the characteristic of the sample gas flow during the sampling time interval is equal to or greater than a corresponding threshold value; determine that supplemental oxygen is provided when it is determined that the change in the characteristic of the sample gas flow is equal to or greater than the threshold value; and determine that supplemental oxygen is not provided when it is determined that the change in the characteristic of the sample gas flow is less than the threshold value.

The invention relates to a ventilation monitoring system comprising a ventilation data capturing device connected between a patient and a ventilator device dedicated to the patient, for collecting ventilation data between the patient and ventilator device; an on-site device; a remote device for communicating with the ventilation data capturing device and the on-site device; at least one processor; and at least one memory device coupled to the at least processor configured to: collect ventilation data from the ventilation data capturing device; transmit the collected ventilation data to the remote device/server for analysis; and generate output data comprising the instructions/commands for actioning on the ventilator device, to provide suitable ventilation support to the patient, or generate output data comprising the status of the ventilator device associated with the ventilation data capturing device.

Detection of unintentional air leaks in a user interface (e.g., mask) of a respiratory therapy system (e.g., a positive air pressure device) is disclosed. One or more sensors (e.g., within a computing device, such as a smartphone) can be moved around relative to the user interface to determine a location and/or intensity of an air leak. The computing device can provide feedback regarding the location and/or intensity of the air leak to facilitate the user locating the air leak, and thus correcting the air leak. In some cases, augmented reality annotations can be overlaid on an image (e.g., live image) of the user wearing the user interface to identify the location of the air leak. The system can automatically detect the type of user interface being used and can provide tailored guidance for reducing the air leaks.

Resuscitation/ventilation systems that include a pressure chamber or cylinder may use a piston articulated within the pressure chamber or shaft to push air and/or a mixture of gas and air into and out of an airway circuit for the purpose of providing mechanical ventilation and/or artificial respiration to a patient. In some cases, the pressure chamber or cylinder may be resident within a canister that fits with a body. The canister may include a motor that moves a shaft connected to the piston up and down, or in and out, within the pressure chamber or cylinder and this movement of the piston may cause a vacuum within the airway circuit and/or the pushing of air or gas out of the airway circuit into a patient’s lung(s).
