Ventilation system during guided insertion of an endotracheal tube

摘要

An endotracheal tube can be inserted into a patient's trachea during resuscitation by using a face mask and a curved guide. The guide is inserted through a flexible port in the face mask and has a curved distal portion that extends into the patient's mouth and hypopharynx. The patient is initially resuscitated by supplying a flow of air/oxygen through the mask. For example, a resuscitation bag can be connected to a rotatable ventilation port on the face mask. Alternatively, a resuscitation attachment with an air filter and one-way valve can be removably attached to the ventilation port of the face mask to enable a health care provider to directly resuscitate the patient. An endotracheal tube is inserted over the distal end of a fiber optic probe. Resuscitation, oxygenation, or artificial ventilation continue without interruption while the fiber optic probe and endotracheal tube are inserted through a flexible port at the proximal end of the curve guide and then advanced along the guide into the patient's airway, thereby allowing the physician to carefully guide the fiber optic probe and endotracheal tube to a position past the larynx while resuscitation continues. The fiber optic probe is then removed from within the endotracheal tube and the mask is removed while leaving the endotracheal tube in place within the trachea./PTEXT
