ABSTRACT:
An apparatus is provided for delivering a fluid to an orifice of a patient. A delivery device, such as a mask or cannula with nostril tubes, has at least one electrode for contacting the patient's skin or other conductive surface. An alarm circuit produces an electrical alarm signal in response to an electrical condition. An electrical interconnection between each electrode and the alarm circuit is provided such that when the electrode is not in contact with the patient's skin or conductive surface the electrical condition is satisfied, thereby producing the electrical alarm signal.
