i.e. he orders 125ml/hr NSS

Where does he come up with the 125? Can't see to hunt down an answer on this. Is it to simplistic to assume its simply based on hydration status? For example a dehydrated pt recieves a higher rate of admiinistration whereas a edematous pt would receive a lower rate? But I thought that was the reason for the hypotensive vs hypertensive fluids. What gives?

For some reason I would think that # must be calculated somehow but I just seem to find a calculation anywehere.

edit: Should note I'm thinking in terms of maintenance i.e. not a pt in the ED who is hypotensive or some such instance.

I was wondering this the other day myself.

Aside from hydration status, and BP, there is also the concern for ensuring a CHFer doesn't go into overload...

I'd love to know where they come up with these numbers though.

Some docs look at lab values to determine the rate. For example......if a pt had a BNP or >1100..... they may order a rate of 20-30cc/hr....if any...... they may also look at the patient's BUN and creatnine.......their electrolytes etc. Our dieticians sometimes "recommend" a certain amt of fluid bolus based on the caloric intake etc.

The average person needs a minimum of 2500mL of fluid every day: daily losses from urination, respiration, digestion... For optimum hydration 3000mL is best. Divide that out and 125mL an hour every 24 hours gives the person optimum hydration.
