• Cardiac outputVolume of blood ejected by the heart per minute.
• ComplianceChange in volume per unit change in pressure.
• Dead spaceVentilated lung that does not take part in gas exchange.
• Fluid responsivenessA rise in stroke volume of >=10% after a preload challenge.
• Functional residual capacityLung volume at the end of a normal passive expiration.
• MAPMean arterial pressure; the average arterial pressure over a cardiac cycle.
• SepsisLife-threatening organ dysfunction caused by a dysregulated host response to infection.
• ShockAcute circulatory failure with inadequate tissue oxygen delivery.
