Answer

380 mm Hg Explanation 1. Calculate the partial pressure of oxygen in room air The partial pressure of oxygen (\( \mathrm{PO}_{2} \)) in room air is calculated as ( 21\% ) of the total atmospheric pressure. Thus, \( \mathrm{PO}_{2} = 0.21 \times 760 \, \text{mm Hg} = 159.6 \, \text{mm Hg} \). 2. Calculate the partial pressure of supplemental oxygen The supplemental oxygen is delivered at a concentration of ( 50\% ). Therefore, the partial pressure of this supplemental oxygen is \( 0.50 \times 760 \, \text{mm Hg} = 380 \, \text{mm Hg} \).
