What is the first step in verifying the position of an endotracheal tube after intubation?

The first step in verifying the position of an endotracheal tube after intubation focuses on the immediate assessment of physiological signs that indicate successful placement. Observing chest rise is crucial because it provides real-time confirmation that the tube is correctly positioned in the trachea. When the tube is in the right place, both sides of the chest should expand symmetrically with each breath, signifying proper ventilation.

This initial visual assessment is essential because it can detect immediate complications associated with endotracheal intubation, such as accidental placement in the esophagus or in a bronchus. It is a quick and non-invasive method for ensuring the patient is receiving adequate ventilation.

Following this, other verification methods such as auscultation of lung sounds, checking end-tidal CO2 levels, and, if necessary, obtaining a chest x-ray can provide additional confirmation of tube placement, but they are typically performed after the initial observation of chest rise. This sequential approach allows for an efficient and effective verification process to ensure patient safety.
