Abstract

The flow of a biological fluid, including ventilation gas and blood, to an organ during controlled life support condition is controlled. For ventilation, a static pressure volume curve for the patient is established in accordance with the Venegas equation, a predetermined pattern of variation over time of the instantaneous respiratory rate and tidal volume from spontaneously-functioning normal lungs of a mammalian species established, data is selected from the pattern which satisfies a specific relationship with respect to the pressure/volume curve, and the patient is ventilated in accordance with the selected data.
