Abstract
A system is for detection of leakage or abnormal resistance in a ventilation system. The ventilation system includes a breathing apparatus which provides a mechanical ventilation to a patient. The system includes a bioelectric sensor arrangement detecting a bioelectric signal indicative of the patient's effort to breathe and a control computer configured to receive the bioelectric signal detected by the bioelectric sensor arrangement. The control computer is further configured to determine a change in the bioelectric signal and to establish leakage or abnormal resistance in the ventilation system based on the change in the bioelectric signal.
Claims21
A method for detection of leakage or abnormal resistance in a ventilation system, the ventilation system including a breathing apparatus configured to provide a mechanical ventilation to a patient, comprising:
- measuring, using a bioelectric sensor, a bioelectric signal indicative of the patient's effort to breathe;
- determining, using a processor of the breathing apparatus, a change in the bioelectric signal;
- and
- determining, using the processor, leakage or abnormal resistance in the ventilation system based on the change in the bioelectric signal,
- wherein the bioelectric signal is at least one of an Edi signal or an EMG signal, indicative of electrical activity of the patient's respiratory muscles, or an EEG signal indicative of electrical activity of the patient's respiratory centres of a brain, and
- wherein the method is performed during ventilation of the patient in a ventilation mode in which the mechanical ventilation of the patient is controlled based on the bioelectric signal.
A system for detection of leakage or abnormal resistance in a ventilation system, the system including a breathing apparatus configured to provide a mechanical ventilation to a patient, comprising:
- a bioelectric sensor detecting a bioelectric signal indicative of the patient's effort to breathe, and
- a control computer configured to receive the bioelectric signal detected by the bioelectric sensor, the control computer further configured to determine a change in the bioelectric signal received from the bioelectric sensor and to determine leakage or abnormal resistance in the ventilation system based on the change in the bioelectric signal,
- wherein the bioelectric signal is at least one of an Edi signal or an EMG signal, indicative of electrical activity of the patient's respiratory muscles, or an EEG signal indicative of electrical activity of the patient's respiratory centres of a brain, and
- wherein the control computer is configured to control the mechanical ventilation provided to the patient by the breathing apparatus based on the bioelectric signal.
