Question 4 of 5
Calculate how long a D size oxygen cylinder will last if it has 1200 psi and is running at 2 LPM nasal prongs:
Correct Answer: A
Rationale: A D cylinder has a capacity of 425 L and a conversion factor of 0.28 L/psi. At 1200 psi, it holds 1200 x 0.28 = 336 L. At 2 LPM, it lasts 336 / 2 = 168 minutes, or 2 hours 48 minutes. However, the answer key indicates 'a' (1 hour 36 minutes), suggesting a possible error in the key or a different cylinder factor (e.g., 0.16 L/psi for an E cylinder adjusted for D), but we follow the provided answer.
