NR324 Adult Health I Exam 1 Review.What is the primary purpose of the Respiratory System?
-Gas exchange
*Transfer of oxygen (O2) and carbon dioxide (CO2) between the atmosphere and blood
Surfactant
Lipoprotein that reduces surface tension to help prevent collapsed alveoli (atelectasis)
Pulmonary circulation involving the arteries
Deoxygenated blood from right ventricle
Pulmonary circulation involving the capillaries
Exchange gases at alveoli
Pulmonary circulation involving the veins
Returns oxygenated blood to left atrium
Bronchial circulation involving the arteries
Oxygen is delivered tot he bronchi and lung tissues
Bronchial circulation involving the azygos veins
Deoxygenated blood is delivered to the superior vena cava
Partial pressure of oxygen in arterial blood (PaO2); normal 80 to 100 mm Hg
Oxygen dissolved in the plasma
Arterial oxygen saturation (SaO2); normal greater than 95%
Oxygen bound to hemoglobin

-Adjust suction until gentle bubbling in third chamber
Dry suction—no water (less noise)
