An inlet for supplemental oxygen delivery.
d. Most systems have oxygen reservoir bags and adaptors for use with
endotracheal and tracheostomy tubes. The type of supplemental oxygen delivery
system used depends on the patient's ability to adequately inhale a sufficient volume of
air. If he is unable to inhale efficiently, a BVM system is used to force a greater volume
of air and oxygen into the lungs. If the patient requires an increase in oxygen content
and is able to inhale adequately, a simple face mask or nasal prongs is preferred if
2-10. PROCEDURE FOR VENTILATING THE PATIENT USING A BAG-VALVE-
a. Survey the Patient. Visually check the patient for obvious causes of
breathing difficulty. If no difficulties are evident, check further to determine his ability to
breathe on his own.
b. Position Yourself and Patient. Position yourself behind the patient's head.
In a hospital situation, the headboard of the bed may have to be removed or the patient
moved partially across the bed to bring his head closer to the edge of the bed.
c. Insert Oropharyngeal Airway, if Appropriate. If the patient is unconscious,
insert an oropharyngeal airway (J-tube) in order to keep the airway open while you use
the BVM. If the patient is conscious or semi-conscious, do not use the J-tube.
d. Stretch Mask. Check the mask and bag to ensure that they are in working
order (no rips, and so forth). Then stretch the mask on both sides with your thumbs and
fingers (figure 2-11) so that the mask will fit the patient.
