Q; Is equal breath sounds a reliable indicator of proper placement of ETT (endotracheal placement) ?


A; No

Atleast per one study, equal breath sounds can be heard in up to 60% of right main stem intubations and can't be count as a reliable indicator of proper placement of ETT. Only CXR and morely, a bronchoscopy is a reliable way to confirm ETT placement.
