Then, we changed the patients to PAV-plus ventilation with 65% support and after 20 minutes we measured the same mentioned parameters plus the respiratory system compliance, resistance and the patients work of breathing. The same procedure was made after changing the patients to PAV-plus ventilation of 50% support.Cited by: 1

Feb 01, 2011 · Patient-ventilator synchrony is a common problem with all patients actively triggering the mechanical ventilator. In many cases synchrony can be improved by vigilant adjustments by the managing clinician. However, in most institutions clinicians are not able to spend the time necessary to ensure synchrony in all patients. Proportional assist ventilation (PAV) and neurally adjusted ventilatory ...
