Patients with Obstructive Sleep Apnea (OSA) are presenting to the operating room, the endoscopy suite, or elsewhere for procedures done under conscious sedation or light general anesthesia. Unfortunately, a large number of OSA patients develop airway obstruction during such procedures. Recently, I developed a means to allow a variety of CPAP mask designs to be connected to an anesthesia machine so as to allow CPAP to be administered during procedures done under conscious sedation or general anesthesia with the patient breathing spontaneously. The use of a CPAP machine is not needed, and high levels of oxygen can be administered. Details here.
