Circuit flow rates

We calculate the flow rates once animal is settled, but the ref guide allows the initial flow rate to be suitable for the patient instead of just automatically turning the flowmeter to 2l/min!!

We used to use the ref guide like this when I worked in a Hospital so thought it would be interesting to update the old copy of mine so it is up to date.

I work it out to be around:

T-piece 560-680mls/Kg/min

Bain 370-450mls/Kg/Min

Mini lack 340-450mls/Kg/min

Lack 225-300mls/Kg/min

(basing it on an animal with a respiratory rate of 15 breaths per min then obviously changing it depending on RR) hope this helps?

We were never taught the actual flow rate per kg in mls. We were taught the Circuits Factors.

T-piece and Bain are 2.5 -3

Lack and Magill are 1-1.5

Duno if that helps tho
