Hyperdynamic phase
Web1 jan. 1984 · In the hyperdynamic phase of septic shock, the peripheral cells have difficulty in extracting oxygen because of the mitochondrial injury secondary to sepsis or endotoxemia. Later in the hypodynamic phase, oxygen extraction elevates the (C [a-v]02), which is similar to what occurs in hypovolemic shock.

Web1 dec. 2024 · The modified shock index (MSI) can be applied to measure the effects of this hyperdynamic phase in sepsis as it is a measurement of the ratio of the heart rate (HR) to the mean arterial blood pressure (MAP). In sepsis, especially in the early course, an increase in the MSI is associated with an increased mortality [6,7].
