Q: Question: Does administration of 100 % oxygen before removal of the laryngeal mask airway affect postanesthetic arterial partial pressure of oxygen?
Answer: The endotracheal tube and laryngeal mask airway are substantially different artificial airways used to ventilate the lungs of anesthetized patients. Breathing 100% oxygen before removing the endotracheal tube results in lung function defects. This study shows that oxygen breathing before removing the laryngeal mask airway has no effect on pulmonary function.
A:
no
