The VPF design eliminates the constant-flow chiller pumps and uses the variable-flow pumps to circulate water throughout the entire chilled water loop (Figure 1, p. 1). Both systems include a bypass line. khatte draws comics

"WebA Servo Ventilator 300 provides volume-controlled ventilation (constant inspiratory flow), as well as pressure-regulated volume-controlled ventilation (PVRC, decelerating inspiratory flow). The PVRC mode provides the set tidal volume by regulating the inspiratory pressure to a value based on the pressure/volume conditions for the previous breath. " - Constant flow ventilatie
