A. PAO2: ________ _ increased; ____________ decreased; _______ remained the same

B. PACO2: ______ _ increased; ____________ decreased; _______ remained the same

C. PCO2: _________ increased; ____________ decreased; _______ remained the same

D. PCCO2: ________ increased; ____________ decreased; _______ remained the same

E. pH: __________ _ increased; ____________ decreased; _______ remained the same

Introduction:

Upper airway obstruction is a clinical condition characterized by the presence of blockage in the upper airway that includes the trachea, the larynx, or the voice box, and the throat. Blockage in the upper airway prevents the body from getting enough oxygen. Upper airway obstruction leads to the diminishing of pulmonary ventilation.

Please refer to Clinical Application Case-2 for further information.

Explanation of Solution

A. PAO2 is the pressure of oxygen in the alveoli. As a result of diminished pulmonary ventilation, the affected lungs receive less oxygen in accordance with the blood flow that remains normal. This results in decreased PAO2. So, PAO2 will be decreased.

B. PACO2 is the pressure of carbon dioxide in the alveoli. As a consequence of the upper airway obstruction, pulmonary ventilation is diminished. The diminishing of pulmonary ventilation decreases the pressure of oxygen. The amount of carbon dioxide increases because of decreased ventilation. So, PACO2 will be increased.

C. PCO2 is the pressure of oxygen in the end-capillary blood and it mirrors the PAO2. As the PCO2 mirrors the changes in PAO2, decrease in PAO2 as a result of upper airway obstruction will lead to a decrease in PCO2...
