Question

you have a patient that meets the indications for cpap. you attachment the cpap to a full d oxygen tank in the residence. your flow rate is 50 lpm. how long will the tank last? 1 point 5 minutes 5.5 minutes 6.2 minutes 6.4 minutes am i right? submit answer

Explanation:

Step1: Recall D tank capacity

A full D oxygen tank has a capacity of 325 liters (standard value for D tank).

Step2: Use time formula

Time ($t$) is calculated by dividing total volume ($V$) by flow rate ($F$), so $t=\frac{V}{F}$. Here, $V = 325$ L, $F = 50$ lpm.

Step3: Calculate time

$t=\frac{325}{50}=6.5$ minutes (approximate, and among options, 6.4 minutes is closest due to possible slight variation in tank capacity definition or rounding).

Answer:

6.4 minutes (the option with "6.4 minutes")
