Abstract
Ventilatory systems and methods are disclosed including a ventilator and at least one sensor in communication with the ventilator. The sensor is configured to monitor a chest wall movement of a patient during ventilation. The ventilator is configured to provide an alarm to a clinician upon detection by the sensor of a threshold change in the chest wall movement of the patient, for example, a threshold change between the monitored chest wall movement and a previously monitored chest wall movement of the patient. The sensor may be located on an exterior surface of the patient's chest and may be, for example, an accelerometer, an optical imaging system, an audio sensor, an electrical impedance sensor or an ultrasound sensor.
Claims20
A ventilatory system comprising:
- a ventilator;
- and
- at least one sensor in communication with the ventilator and configured to monitor a chest wall or abdominal movement of a patient during ventilation,
- wherein the ventilator is configured to provide an alarm to a clinician upon detection by the at least one sensor of a threshold change in the chest wall or abdominal movement of the patient.
A method of detecting inadequate ventilation of a patient comprising:
- monitoring a chest wall movement of the patient;
- determining if a threshold change in the chest wall or abdominal movement of the patient has occurred;
- and
- triggering an alarm if the threshold change in the chest wall or abdominal movement of the patient has occurred.
A non-transitory computer-readable storage medium encoded with a program that, when executed by a processor detects inadequate ventilation of a patient and causes the processor to perform the steps of:
- monitoring a chest wall or abdominal movement of the patient;
- determining if a threshold change in the chest wall or abdominal movement of the patient has occurred;
- and
- triggering an alarm if the threshold change in the chest wall or abdominal movement of the patient has occurred.
