WebPoor peripheral perfusion is seen as an early sign of sepsis. Cold stress/hypothermia. In general, associated with a skin temperature <36.5°C (97.7°C). Hypotension usually with shock. Hypoventilation can cause poor perfusion. Respiratory distress syndrome. Infants with respiratory distress syndrome have poor perfusion and lower perfusion index. WebDec 11, 2024 · Note that “microischemia” may threaten the energy metabolism of individual cells if most nearby capillaries become occluded or poorly perfused. The greater problem, however, is the disproportionate amount of blood that passes through other capillaries at short transit times, introducing “shunts” for oxygenated blood through the tissue.
