The interstitial fluid pressure is the hydrostatic pressure of the fluid between the solid tissue elements such as cells, fibers and vessels. Guyton measured negative pressures in chronically implanted perforated capsules, which he considered to be the true interstitial pressure in the subcutis [1], Others showed that a cotton wick inserted in a needle or catheter recorded a negative pressure in the subcutis within a few minutes just as the Guyton capsule did [2, 3].
