Question

1. Patient A has a dead space volume of 150ml, a tidal volume of 450ml and a respiratory frequency of 10. Patient B has a dead space volume of 150ml, a tidal volume of 300ml and a respiratory frequency of 15.

1. Which patient has the most effective ventilation?

2. Why?

Answer 1

In the above question -

In case of patient A-   Tidal volume= 450 ml,,,,, & Respiratory frequency = 10

So, the patient can take 450/10 ml = 45 ml air per each respiration..

In case of patient B-   Tidal volume= 300 ml,,,,, & Respiratory frequency = 15

So, the patient can take 300/15 ml = 20 ml air per each respiration..

So, In this case Patient A has the most effective ventilation.. Because- he can take more air per each respiration with less effort..
