Breathing circuit with embedded acoustic reflectometer |
abstract |
An instrument may continuously monitoring acoustic reflections from within and/or beyond an intubation tube positioned within the mouth of a patient while the patient is breathing. The instrument may include an acoustic reflectometer configured to detect the acoustic reflections. An acoustic flow channel may contain the acoustic reflectometer within it. The acoustic flow channel may be configured to acoustically couple the acoustic reflectometer to an end of the intubation tube, but to substantially block the free flow of expiratory gas from the end of the intubation tube through the acoustic flow channel. A gas flow channel may be separate from the acoustic flow channel and may be configured to allow the free flow of expiratory gas from the end of the intubation tube through the gas flow channel. |
