I placed a ng tube in an intubated patient - physician was not concerned "there is no way an ng tube will go into the lungs with the patient being intubated". Auscultated - I heard air over the stomach. We x-rayed as per protocol . . the physician said "steph, come here for a sec" . . . . .walked over to the x-ray and there was the ng tube in the bronchus.
Never say never.
