What does +2 capillary refill mean?
Capillary refill time Normal CRT is 1 to 2 seconds. This is consistent with a normal blood volume and perfusion. A CRT longer than 2 seconds suggests poor perfusion due to peripheral vasoconstriction.
What does increased capillary refill mean?
A prolonged capillary refill time may be a sign of shock and can also indicate dehydration and may be a sign of dengue hemorrhagic fever and decreased peripheral perfusion. Prolonged capillary refill time may also suggest peripheral artery disease.
What is normal capillary refill?
