Abstract
A system and method for sleep monitoring, diagnosing and sensing temperature and pressure for a breathing cycle of a patient including a sensing device suitable for both nasal and oral breath monitoring for measuring respiratory air wave and airflow information during a sleep apnea diagnostic session and processing the acquired air wave and airflow breathing information for input to conventional polysomnography equipment.
Claims21
1-49. (canceled)
A device for determining a breathing cycle of a patient, the device comprising:
- a first sensing device for sensing air pressure during the breathing cycle of the patient;
- and
- a second sensing device for sensing temperature of the patient's inspiration and expiration during the breathing cycle concurrently with the pressure sensing,
- wherein the first sensing device for sensing pressure includes a cannula for receiving a sample of expiration airflow from the patient, and the second sensing device comprises at least one thermistor located along a respiratory airflow path of the patient for sensing temperature of the airflow, and
- the cannula includes an integral holster which directly secures a portion of the thermistor, relative to the cannula, to facilitate locating the thermistor in a desired region of the respiratory airflow path of the patient,
- the holster supports the thermistor in position along the respiratory airflow path of the patient but spaced from the patient and the cannula, and
- the device provides output signals concurrently indicating a measured pressure and a measured temperature of the patient's breathing cycle.
