A capillary refill time of three seconds or more should be considered
abnormal
. The results show that an abnormal CRT of 3 seconds or more increases the likelihood of a serious outcome including death and dehydration – however a normal CRT does not make a serious outcome less likely.
What does capillary refill time indicate?
Capillary refill time (CRT) is a measure of the time it takes for a distal capillary bed, such as those found in the fingers,
to regain colour after pressure has been applied to cause blanching
. A prolonged CRT may indicate the presence of circulatory shock.
Is a capillary refill of 3 seconds bad?
“Emergency signs include: … signs of shock (capillary refill longer than 3 seconds; and fast weak pulse)…. Children with emergency signs require immediate treatment to avert death.” “If capillary refill is longer than 3 seconds,
check the pulse
.”
What is a capillary refill time greater than 2 seconds indicative of?
Capillary refill time
This is consistent with a normal blood volume and perfusion. A CRT longer than 2 seconds suggests
poor perfusion due to peripheral vasoconstriction
. Peripheral vasoconstriction is an appropriate response to low circulating blood volume and reduced oxygen delivery to vital tissues.
What does good capillary refill mean?
The CRT is largely recommended in the routine of unwell patients and should last less < 2 seconds. If the color is pink after there is no more pressure; it indicates a
good blood flow to the finger
. t It’s part of the assessment of patients seriously ill.
What does a capillary refill test indicate?
The capillary nail refill test is a quick test done on the nail beds. It is used to
monitor dehydration and the amount of blood flow to tissue
.
What is a good capillary refill time?
It is a simple test to measure the time taken for colour to return to an external capillary bed after pressure is applied, typically by pressing the end of a finger with the thumb and forefinger. Normal capillary refill time is usually
2 seconds or less
.
What does an abnormal capillary refill indicate?
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 in adults?
The refill times they identified as normal do not exceed
1.9 seconds for males
and 2.9 for females aged 18 to 64, and 1.8 seconds in both genders aged 65 or more.
What affects capillary refill?
Local skin temperature
affects CRT in both adults and children. In adults, the immersion of a hand into cold water at 14°C prolonged CRT.
9
. Fingertip skin temperature varied with the ambient temperature and each 1°C reduction in skin temperature was accompanied by a 0.21 second increase in CRT.

How do you check peripheral circulation?
Examination of peripheral circulation is easily
done by touching the skin
, measuring capillary refill time (CRT) or even by observing the skin mottling pattern.
What does Terry nails mean?
Fingernails: Possible problems
Terry’s nails can sometimes be attributed to
aging
. In other cases, Terry’s nails can be a sign of a serious underlying condition, such as liver disease, congestive heart failure, kidney failure or diabetes.
Why is capillary refill important?
The capillary refill time is generally thought to be
the quickest assessment of early hypoperfusion
. Capillary refill time is faster to obtain than a blood-pressure measurement and is particularly helpful in a loud or busy ED. A delay in the capillary refill time (>2 seconds) indicates hypoperfusion of the skin.
How do you check circulation?
How to check: Compare the temperature of both sides. If fingers or toes are cold,
put a blanket on to cover the fingers or toes and check again in one hour
. Normal: Pink within 3 seconds or less. Less than 3 seconds is rapid.
