Abstract

An arrangement and method is provided for controlling operational characteristics of medical equipment. A pressure sensor associated with the caregiver is arranged to sense changes in air pressure that correspond to breathing activity of the caregiver. The pressure sensor may comprise a neckband, headset, or the like. In the arrangement shown, a headset that is worn by the caregiver includes a disposable tube connected to a pressure transducer such that the pressure sensor senses changes in air pressure in the tube. An open end of the tube is positioned near the mouth of the caregiver to receive changes in airflow from the caregiver'"'"'s mouth. The pressure sensor is in communication with a controller associated with the ventilator. The controller is arranged to control at least one operational parameter of the ventilator, such as the delivery of respiratory support to the patient or actuation of an oxygen flush valve on the ventilator, based upon the changes in air pressure sensed by the pressure sensor.

Claims

1. A method of controlling at least one operational characteristic of medical equipment to provide medical care to a patient, the method comprising the steps of:

sensing breathing activity of a caregiver; and

controlling the medical equipment to provide medical care to a patient based upon the sensed breathing activity of the caregiver;

wherein the step of sensing breathing activity of the care giver comprises the step of sensing a puff or a sip provided by the care giver to a pressure sensor device;

wherein the medical equipment comprises a ventilator that is controlled based upon the sensed breathing activity.

2. The method of claim 1, wherein the ventilator is controlled to provide inspiratory support when a puff is detected and to actuate an oxygen flush valve when a sip is detected.

3. The method of claim 1, further comprising the step of controlling the operational parameter of the medical equipment based upon at least one of the duration of the breathing activity and the magnitude of the breathing activity.

4. A method of controlling at least one operational characteristics of medical equipment to provide medical care to a patient, the method comprising the steps of:

controlling medical equipment based upon sensed breathing activity of a first person caregiver to provide medical care to a second person patient;

wherein the step of sensing breathing activity of a caregiver comprises the step of sensing a puff or a sip provided by the caregiver to a pressure sensor device.

5. The method of claim 4, wherein the medical equipment comprises a ventilator that is controlled based upon the sensed breathing activity.

6. The method of claim 5, wherein the ventilator is controlled to provide inspiratory support when a puff is detected and to actuate an oxygen flush valve when a sip is detected.

7. The method of claim 4, further comprising the step of controlling the operational parameter of the medical equipment based upon at least one of the duration of the breathing activity and the magnitude of the breathing activity.
