“…As a marker of peripheral perfusion, the PI is expressed as the ratio of the pulsatile component of light (i.e., the arterial compartment [AC]) to the non-pulsatile component of light (i.e., the direct current [DC] in other tissue) reaching the pulse oximetry sensor, and this value is independent of patient oxygen saturation. 9 The PI can be expressed by the following formula: PI = (AC/DC) x 100 [%]. 10 The value PVI is a noninvasive dynamic variable that reflects fluid status.…”

“…Segundo Lima (2005), a utilização da circulação cutânea como parâmetro é uma ferramenta de grande valia, utilizando apenas a superfície dorsal das mãos ou os dedos obtemos a percepção de diferença na temperatura. Como por exemplo, pacientes que apresentam extremidades frias, sugerem oclusão vascular periférica, evidenciando sinais clínicos de pele fria, palidez mucosa e aumento no tempo de preenchimento capilar (TPC).…”

“…In his description, he emphasized the cold, clammy and mottled skin associated with high heart rate observed in war casualties. Today, monitoring of the peripheral circulation of the skin, subcutaneous tissue and muscle can be done noninvasively in contrast to the need for intravascular catheters, transoesophageal probe insertion, blood component analysis or penetration of the skin used in more traditional hemodynamic monitoring in the ICU [2]. Paradoxically, the technical advancements in peripheral tissue perfusion monitoring were necessary for the renaissance of the most basic approach to peripheral tissue perfusion assessment, clinical examination, in the scientific literature.…”
