CoVent~Prime is a flowgenerator both in volume and pressure control modes. The modes of ventilation available are CMV/AV(VC), CMV/AV (PC), SIMV (VC), SIMV (PC), Spontaneous, BIPAP and APRV. Besides, a Standby Mode is providedwhere the ventilator can be made inoperative temporarily but keeping the setparameters stored in the memory.
It also provides for Pressure SupportVentilation (PSV), PEEP/CPAP, Apnea Back-up ventilation and ExtendedInspiratory Phase (EIP). During apnea, the ventilator automaticallyswitches over to CMV (VC) mode. The apneabackup ventilation will be indefault setting.The parameters available onthe screen are mode of operation, set tidal volume, expired tidal volume,expired minute volume, peak inspiratory pressure, mean airway pressure, setfrequency, total frequency (including spontaneous breaths), I / E ratio andinspiratory time.
Theinspired oxygen concentration (FiO2) can be adjusted from 21to 100%. The monitored FiO2 at any instant is displayedon the panel. The Oxygen blender is servo controlled with closed loopfeedback correction.
