Abstract
A ventilator for respiratory care, intended for connection to a patient, avoids needless alarms, caused by a patient's attempts to speak and needless suffering because of the patient's inability to trigger an alarm, by having a sound detector arranged to detect and identify sounds made by the patient, preferably intentionally. A control unit is operatively connected to the sound detector acts on at least one function in the ventilator on the basis of sounds identified by the sound detector.
Claims15
A ventilator comprising:
- a tube adapted for connection to a patient for providing respiratory care dependent on at least one of a plurality of ventilator functions;
- a sound detector for detecting and identifying sounds made by said patient;
- an alarm;
- and
- a control unit operatively connected to said sound detector for influencing at least one of said plurality of ventilator functions dependent on the sounds identified by said sound detector, said control unit being connected to said alarm and activating said alarm dependent solely on identification by said sound detector of sounds made by the patient.

A ventilator comprising:
- a tube adapted for connection to a patient for providing respiratory care dependent on at least one of a plurality of ventilator functions;
- a sound detector for detecting and identifying sounds made by said patient;
- means for identifying a predetermined discrepancy between a volume of inspired breathing gas and a volume of expired breathing gas;
- an alarm;
- and
- a control unit operatively connected to said sound detector for influencing at least one of said plurality of ventilator functions dependent on the sounds identified by said sound detector said control unit being connected to said alarm and normally triggering said alarm if said predetermined discrepancy occurs, and said control unit inhibiting said alarm dependent on identification of sounds made by the patient by said sound detector.
