What waveform will I see with a Right Mainstem intubation?
The waveform shape may appear normal and the EtCO2 value may be within normal limits as well. The alveoli of the Right side are all contributing to the EtCO2 value. This is especially true in the first few moments post extubation. A chest X-ray is the only true method to identify where in the airway the tip of the ETT is positioned. The patient’s SpO2 may drop when the ETT is in the Right Mainstem bronchus.
