Cerebral perfusion in sepsis-associated delirium

Table 3 Haemodynamics, cerebral perfusion, and respiratory parameters

	Sepsis-associated delirium	No sepsis-associated delirium	P value
Mean arterial pressure, mm Hg	75 (57–87)	85 (73–94)	0.1
FV, cm/second	76 (40–97)	48 (45–98)	0.3
Cerebral TOI, percentage	59 (49–74)	65 (59–69)	0.2
SaO₂, percentage	97 (91–100)	99 (93–100)	0.2
PaCO₂, kPa	5.4 (3.7–9.4)	5.3 (4.5–5.5)	0.7
Ear temperature, °C	37.1 (35.0–38.6)	37.3 (36.3–38.5)	0.5

All values are shown as median (range) and represent means of data collected during a 60-minute measurement. FV, cerebral blood flow velocity in the middle cerebral artery; PaCO₂, arterial partial pressure of carbon dioxide; SaO₂, arterial oxygen saturation; TOI, tissue oxygenation index. TOI and FV are averaged values from both cerebral hemispheres. P values were calculated with the Mann-Whitney U test.
