Question

(Oxygen System) Gaseous oxygen pressure should be _____ - _____.

Option 1: 1000 - 2000 psi
Option 2: 1500 - 3000 psi
Option 3: 1800 - 2200 psi
Option 4: 1200 - 2500 psi

Answer 1

The correct range for gaseous oxygen pressure should be 1200 - 2500 psi, which is option 4.

Step-by-step explanation:

The correct range for gaseous oxygen pressure should be 1200 - 2500 psi, which is option 4. It is important to note that this pressure range is lower than the external air pressure. This means that oxygen will flow from the inspired air in the lung (PO₂ = 150 mm Hg) into the bloodstream (P0₂ = 100 mm Hg).
