BNP (brain natriuretic peptide)
Normal <100 pg/mL. Used to diagnose Heart Failure.
100-299 mild
300-599 moderate
600-899 severe
>900 emergency
PAWP (pulmonary artery wedge pressure)
Normal 4-12 mmHg
> 12mmHg seen with excess fluid( overload)
<4mmHg seen in fluid deficit( dehydration).
Albumin
Normal 3.5 -5.0g
protein in blood; maintains the proper amount of water in the blood.
Given to patient with poor Nutrition Status, Burns, Shock. Also given in Edema patient to
mobilize the fluid into vascular space.
Creatinine
