Abstract: The American Society of Anesthesiology Task Force on Sedation and Analgesia found druginduced respiratory depression and airway obstruction to be the primary cause of morbidity associated with sedation and analgesia.Similarly, if a patient in the operating room is anesthetized to be intubated, but the intubation is difficult, the patient requires immediate respiratory support until a more intensive intubation attempt can be made, to prevent severe morbidity.The typical approach in these cases is to temporarily ventilate the affected patient by hand, using a face mask and a bag that is periodically squeezed to deliver breaths.This requires skill, both hands, and completely involves one clinician who is not able to assist elsewhere.Intensive Care Unit ventilators are an option for ventilating patients with a mask in hospital settings, but they are bulky, expensive, and complicated, and require specially trained personnel.Our innovative device provides continuous positive airway pressure which helps prevent the airway from obstructing due to soft tissue collapse.It also monitors tidal volume, respiratory rate, and airway resistance.If a respiratory complication is detected, it increases respiratory support to provide a breath to the patient and warns the clinician.In effect, it reduces respiratory complications and replaces the need for manually bag-ventilating the patient.The tested algorithms create reliable and continual respiratory support and monitoring even in the presence of large or varying leaks around the patient's face mask.Using a modern blower motor and a strategy to minimize power consumption, our ventilator is small (about 8X6X2 inches), operates without compressed gas, and can run on batteries for up to 8 hours at a time if needed.An early prototype of the technology has shown very good performance in preliminary bench testing on a manikin.
