Helium-oxygen gas therapy. Use and availability for the emergency treatment of inoperable airway obstruction.
Inoperable obstruction of the upper airway due to extrinsic malignancy may present as respiratory failure. We treated such a patient for 48 hours with 80 percent: 20 percent helium-oxygen delivered by a nonrebreathing mask while chemotherapy and radiation therapy reduced the tumor size. The need for intubation, mechanical ventilation, and high risk surgical intervention was avoided through the use of this gas therapy. We then surveyed San Francisco Bay area hospitals and found that fewer than one half could provide this potentially lifesaving gas therapy in an emergency situation. Physiologic basis of helium-oxygen gas therapy is reviewed and recommendations made for its use and availability.
