When pressure is put upon a nail, it will turn white. Capillary refill is the returning of blood to that nail, usually taking 1-2 seconds. This is used to assess circulation to the extremity in question
Capillary refill refers to how quickly the color returns to the external capillary bed following pressure that has been applied to an area. A brisk capillary refill means that the color returned to the capillary bed rather quickly.
The normal capillary refill time in sheep is typically less than 2 seconds. It is an important indicator of peripheral perfusion and cardiovascular health in sheep. Longer refill times may suggest circulatory problems or dehydration.
it can be done about any were on a child but on a adult on the finger nails
. Normal refill time is less than 2 seconds.
Depending on the context and severity, simple tests include orthostatic vital signs, evaluation of capillary refill, and palpation of temperature.
Shock, hypothermia, peripheral vascular disease

A capillary time, or capilllary refill time is how long it takes for your capillaries to refill. The best way to test this squeeze the tip of your finger, then let go. Time how long it takes to go from white to normal color. So a 6 second capillary time is one in which this takes 6 seconds Normally it should happen fairly quickly In the medical world anything over 2 seconds is bad
you dont you replace the whole thing
Capillary Coagulation Test
capillary refill is when you push on someone's fingernail. the nailbed should turn white and then turn pink again in 2 seconds once you take pressure off. this is a test to ensure that there is proper profusion in the extremities. when your hands are cold, the capillaries in your fingers and extremities are constricted. this could be for many reasons (eg: shock, cold environment, etc.) since the vessels are constricted it will take longer for them to refill when pressure is applied to the nail bed. capillary refill longer than 2 sec that means there is less than adequate profusion.
Skin should be pink, warm, and have one- to two-second capillary refill. Conversely, tissue that is pale or blue, cool, with no refill or rapid refill may indicate a problem with blood flow.
