ABSTRACT:
An endotracheal assembly comprises an endotracheal tube, a malleable obturator inside the tube for enabling a placement of a distal end of the tube into a patient's trachea, and a colorimeteric carbon dioxide indicator mounted to the obturator for determining a passage of carbon dioxide through the tube upon a placement of the tube in the patient. The indicator may be removably connected to the obturator, for example, at the distal end thereof. In addition, cooperating locking elements are provided for releasably locking the indicator to the obturator.
