This is called blanching. Once the tissue has blanched, pressure is removed.While the patient holds their hand above their heart, the health care provider measures the time it takes for blood to return to the tissue, indicated by a pink color returning to the nail.How to prepare for the testRemove colored nail polish before this test.How the test will feelThere will be minor pressure to the bed of your nail, which should not cause discomfort.Why the test is performedTissues need oxygen to survive.

Why do you blanch food before freezing it?
Blanching is the scalding of vegetables in boiling water or steam. Blanching slows or stops the action of enzymes. Up until harvest time, enzymes cause vegetables to grow and mature. If vegetables are not blanched, or blanching is not long enough, the enzymes continue to be active during frozen storage causing off-colours, off-flavours and toughening. Blanching time is crucial and varies with the vegetable and size of the pieces to be frozen. Under-blanching speeds up the activity of enzymes and is worse than no blanching. Over-blanching causes loss of flavour, colour, vitamins and minerals.
