Abstract
An apparatus for determination of a recruitable volume in a lung has a control system connectable to a pneumatic unit and to a measurement system and operable to, at a first point in time, regulate the pneumatic unit to generate a first test breath having predetermined parameters with respect to flow and/or pressure of the gas flow, register volume and pressure in the lung during the first test breath, measured by the measurement system. The control system is at a operable second point in time, to regulate the pneumatic unit to generate a second test breath identical to the first test breath, register volume and pressure in the lung during the second test breath, measured by the measurement system. The control system compares the registered volume and pressure for the first test breath and the second test breath, and determines a recruitable volume based on the comparison.
