automatically calculates the target alveolar ventilation and patient’s RR. Target Va Calculator Used to manually calculate alveolar ventilation by entering the patient’s height, spontaneous breath rate and previously-measured Minute Ventilation (MV) or Tidal Volume (Vt). iVaPS is a key feature of resmed’s Stellar™ 150 ventilator.
