How to Measure Ventilation on Sedated Patients

For patients who are getting IV sedation with an oxygen cannula for supplemental O2, you can measure the respiratory rate and end tidal CO2 trending using the sampling line that you usually put on a circuit. Here's how:

Using an 18 or 20 g catheter, pierce the nasal cannula at the area of the nasal prongs.

1Cut the tip of the catheter that protrudes.

2Screw the luer lock tips of the sampling line to the catheter.

3The monitor will show a tracing that provides a respiratory rate and end tidal CO2 that you can trend.
