Ribs move outward and downward during inspiration
Oxygen-rich ( O2) air enters alveoli during each inspiration
Cells give off CO2 into the capillaries, which is then removed from the body during exhalation.
The thoracic cavity decreases during exhalation, creating a higher pressure for air to be forced out.
NPA's may be successful for use in a patient WITH a gag reflex.
The Jaw -Thrust maneuver is required for patients suspected of having cervical spine compromise.
OPA's are contraindicated for patients having a suspected skull fracture.
NPA's are to always be inserted so thet the bevel is facing the septum at the end of insertion.
Right nostril is larger in most patients
The curve and bevel allow the NPA to be inserted AND have the bevel face the septum at end of insertion if in the right nostril
More natural mucus in the nostril of all patients allows right side insertion to be easier.
The measured length of corner of mouth to earlobe better reflects the perfect depth of the right nare(nostril)
