摘要:
Techniques for emergency apneic oxygenation include a cannula having a longitudinal inner passage with an inner diameter. A distal portion has a first outer diameter greater than the inner diameter, and is made of shape memory material shaped to bend in a first direction along the inner passage. A cannula base has a second outer diameter greater than the first outer diameter. A distance from a distal end of the cannula to a proximal end of the distal portion of the cannula is less than a distance from a surface of a throat of a subject to a distal surface of an airway of the subject. The inner passage is configured to pass a catheter connected at a proximal end to an oxygen source. In various embodiments, the cannula is used with a trocar and, optionally, a system base, or supplied in a kit with a catheter.
