  • To tap in medical parlance is to access and remove fluid from an internal compartment, usually but not always an abnormal fluid collection.

    A thoracentesis or paracentesis would both be examples of taps. A spinal tap is an example which doesn't aim to drain a pathological fluid pocket.

    Usage: "Mr Carver's got a pleural effusion on decubes, but it looks too small to tap."
