Abstract
The present invention provides for a unique modification of the intravenous catheter, attached to the terminal line of the mass spectrometer and the use of a disposable nasal oxygen cannula provide an effective and efficient port to monitor end tidal carbon dioxide (PETCO2) in unintubated, conscious, spontaneously breathing patients who are receiving administration of local and regional anesthesia or during recovery from residual general anesthesia.
Claims10
An apparatus for measuring carbon dioxide content in the exhaled air of a patient while simultaneously insufflating a treating gas into the nose of the patient, the apparatus comprising:
- a nasal cannula having two nares wherein the nasal cannula is modified to contain a catheter adapted to fit within one nare of the nasal cannula, further wherein the catheter is connected into a gas sampling line wherein the sampling line is connected to a capnometer.
A method for monitoring end tidal CO2 in a patient comprising providing a nasal cannula to a patient wherein the nasal cannula is modified to contain catheter adapted to fit within one nare of the nasal cannula, further wherein the catheter is connected into a gas sampling line wherein the sampling line is connected to a capnometer.
An apparatus comprising a catheter having a tapered end and a housing component.
