ABSTRACT:
A respiratory valve apparatus with a housing having a upper entry port and an opposite endotracheal tube connection port, along with a resuscitation bag connection port and an opposite respirator connection port. A rotational valve assembly with an inner channel fits within a chamber formed in the housing. The rotational assembly switches and indexably locks between two positions whereby the channel aligns the entry, endotracheal, and respirator ports in one position, and aligns the entry, endotracheal, and resuscitation ports in the second position. A guide fixture can be attached to the entry port to help steer the catheter through the apparatus. An elongated protective bag can be sealably attached around the catheter to prevent external contact with the catheter surfaces when it is withdrawn.
