Suctioning cardiac surgical patients through the endotracheal tube while they require artificial ventilatory support produces a fall in arterial oxygen tension which can precipitate a cardiac arrest. A review of the literature revealed that a tentative clinical protocol could be developed which, under controlled circumstances, could alleviate or minimize the degree of oxygen desaturation. This essay not only illustrates the evolution of the protocol but describes the process of implementation and offers a method to systematically evaluate its effects.
