supplement 0.5 mEq/kg/h add KCl to IV fluid bag to total 20 mEq/l, and VM,HM
administer at maintenance rate. May add total

of 40 mEq/l to fluid bag if serum [K ]

<3.5 mEq/l, or 60 mEq/l if serum [K ] <3 mEq/l,

or 80 mEq/l if serum [K ] <2.5 mEq/l. Never
administer more than 0.5 mEq/l/hr (i.e., never
bolus IV fluid supplemented with KCl).

Salt [H]) on serum [K ] (e.g., PVCs, VT). Serum [K ] should be
measured on blood drawn in green-top
(heparin) tubes, not red-top, to minimize in

masking hypoK . KCl: 1 mEq = 75 mg. K
gluconate: 1 mEq = 234 mg. K citrate:
1 mEq = 108 mg. KHCO 3 : 1 mEq = 100 mg.
Tumil K: 2 mEq (468 mg) K gluconate per
tablet, ¼ tsp powder, or ½ tsp gel.

arterial blood pressure and could trigger

compensated cat with heart disease via reflex
sinus tachycardia; not recommended in cats
with preexisting HCM.
