Like drops per minute?

(Total volume) X (drip set) / minutes infusing

Minute volume = tidal volume x respiratory rate

Tidal volume is roughly 8-10ml/kg

As tidal volume decreases, rate must increase to maintain adequate minute volume. If rate decreases, tidal volume would have to increase to maintain minute volume (though that variable is fairly limited due to lung capacity)

Does that answer your question, or is there something else you're not understanding? Pulmonary function can go as in depth as you want, but that's essentially the basic concept.

minute volume = Liters of air per minute

tidal volume expressed in Liters per breath

respiratory rate expressed in breaths per minute

so, as @STXmedic said:

tidal volume x respiratory rate = minute volume

You just need to understand the concept and be able to judge the depth/quality of respirations.

Edit: just realized that this is just for NREMT testing purposes.

Yah.. I had a question from the NREMT, regarding calculating the minute volume....

Depending on what values they give you, The Total ventilation or the Minute Volume (Ve) is the Tidal Volume X Respiratory Rate (Avg 15/min 70kg Male)

So remember the tidal volume is mL and the respiratory rate is per min so the total ventilation comes out as mL/Min

Example

Vt = 500ml

f (Respiratory Rate) = 15

500mL X 15/min = 7500 mL/Min

I dont know how much more advanced they go on that for the nmret emt, there are many other ways you could get to the tidal volume depending on what they give you etc.
