<unk>  time is a quick and cheap way to indicate decreased peripheral perfusion and may indicate cardiovascular or respiratory dysfunction. It has also been used to assess or diagnose diseases of the peripheral circulatory system such as Raynaud's syndrome and hand–arm vibration syndrome. There is disagreement as to whether the test is useful, however, and it is poorly standardised. Poor finger or toe<unk>  time is a contraindication for the use of compressive techniques to treat peripheral oedema. In veterinary medicine, poor gum<unk> T may be an contraindication for use of anaesthesia, as the likelihood of anaesthesia being fatal is higher if there is an underlying heart or lung problem. Gum<unk> T also used to monitor health during anaesthesia.
