Capillary perfusion pressure is the source of life for all the cells in our body, and yet, it averages a modest 22 mmHg throughout most systems in the body. Venous capillary closing pressure is about 12 mmHg, and arterial capillary pressure about 32 mmHg [1]. This delicate homeostasis can be upset by something as simple as excessive external pressure on tissue. This situation requires two unyielding surfaces: one an underlying bony prominence and the other an external plane such as a bed, chair, or even a transport gurney. The most common bony surfaces involved, in order of occurrence, are the sacrum, calcaneus, ischium, and greater trochanter [2]. In fact, these areas are subject to pressure exceeding 30 mmHg when lying supine, sitting, or lying on the side, respectively [3]. This situation is usually benign as our autonomic nervous system prompts us to shift our weight frequently to avoid chronic pressure.
