Oral gas catheters and methods of inducing gas in a patient orally. The oral gas catheter includes one or more delivery cannulas configured to be inserted into the patient's mouth with a distal end of the delivery cannula disposed adjacent the patient's laryngeal inlet, and a clip disposed on the delivery cannula. The clip is configured to secure the delivery cannula to a tooth of the patient. The oral gas catheter may have two such delivery cannulas and clips with the delivery cannulas coupled together by a coupler. The delivery cannulas are placed in an operative position in a patient's mouth and secured in the operative position by releasably securing the clips to the patient's teeth. The oral gas catheter makes it possible to bypass the nasal cavity and deliver oxygen or other gas directly adjacent the laryngeal entrance and into an anatomical dead space of the airway.

The present invention includes a system and device for aiding in the diagnosis of a physiological abnormality resulting in detectable, measurable variations in contents of breathed air. The system includes a handheld unit defining an airway, wherein the airway includes a plurality of sensors adapted to measure a plurality of parameters related to the presence of a physiological abnormality. The system further includes a control unit remotely connected to the handheld unit. The control unit includes a controller adapted to receive input signals from the handheld unit and remit output signals in response thereto. The output signals are usable by a user in determining the presence or absence of a physiological abnormality. The control unit further also can include a display adapted to display the output signals to a user thereby easing the determination of the physiological abnormality. The system further includes a mouthpiece selectively connectable to the handheld unit. The mouthpiece can include a filter adapted to substantially prohibit the passage of germs into the airway of the handheld unit.

An airway adaptor includes: a gas passage into which a respiratory gas of a subject is to flow; a respiratory gas introducing portion which is configured to guide the respiratory gas expired from at least one of nostrils and a mouth of the subject, to the gas passage; and an airway case on which a temperature sensor that is configured to detect a temperature change of the respiratory gas flowing into the gas passage is mountable.

A water filter system for a CO.sub.2 sampling line positioned between a patient and a patient monitor to receive patient exhalation. The filter system includes at least one hydrophobic filter that adsorbs and prevents water from reaching the patient monitor. Alternatively, the filter system may include both a hydrophobic filter and a hydrophilic filter and optionally a desiccant.

The present disclosure presents methods, systems and devices for performing capnography (respiratory CO.sub.2) monitoring using a respiratory CO.sub.2 sensor and a breath tracking mechanism for tracking and/or detecting phases of the breath wherein the measurements of the CO.sub.2 sensor may provide baseline CO.sub.2 values, and modulate/quantify the respiratory CO.sub.2 levels according to the baseline values.
