Regulating alveolar ventilation to a prescribed target.



Maintaining a pre-set target for alveolar minute ventilation.

What’s the problem?

Changes in airway resistance, body position, sleep stages and atrophy of the respiratory muscles can compromise your patient’s ventilation.


What does iVAPS do?

iVAPS* is designed to maintain alveolar minute ventilation at a pre-set target level. Alveolar ventilation was chosen because gas exchange occurs at the alveoli level. This makes it particularly suitable for adults with chronic respiratory failure whose condition and ventilation needs are likely to change. Conventional pressure support modes target total tidal volume or minute ventilation.


How does it work?

  1. iVAPS improves ventilation by regulating alveolar ventilation to a pre-set target while taking account of tidal volumes, respiratory rates and the anatomical dead space in your patient’s airways.
  2. iVAPS is an automated mode. It rapidly and gently maintains your patient’s unique alveolar ventilation target and stabilises blood gases by adapting the delivered ventilation to maintain stable breathing, even when your patient’s ventilatory needs change and without affecting sleep quality.1
  3. iVAPS is designed to make NIV setup less complex and time-consuming for clinicians. The device calculates an appropriate alveolar ventilation value if the clinician enters the required patient values (height, target patient rate and one of tidal volume, minute ventilation or Vt/kg). Alternatively, the Learn Targets feature uses a short recording of the patient’s breathing to automatically define suitable respiratory rate and alveolar ventilation values.
