Proportional assist ventilation (PAV): a significant advance or a futile struggle between logic and practice?
نویسندگان
چکیده
Proportional assist ventilation is a promising addition to other more conventional modes of mechanical ventilation with the theoretical advantage of improving patient-ventilator interaction. It may also be of use as a diagnostic tool in the control of breathing in mechanically ventilated patients.

Short-term effects of nasal proportional assist ventilation in patients with chronic hypercapnic respiratory insufficiency.
Proportional assist ventilation (PAV) has recently been proposed as a mode of synchronized partial ventilatory support. This study evaluates the short-term effects of nasal PAV on arterial blood gases in stable patients with chronic hypercapnia. Forty two patients (30 with chronic obstructive pulmonary disease (COPD) and 12 with restrictive chest wall disease (RCWD) due to kyphoscoliosis) under...
متن کاملData on respiratory variables in critically ill patients with acute respiratory failure placed on proportional assist ventilation with load adjustable gain factors (PAV+)
The data show respiratory variables in 108 critically ill patients with acute respiratory failure placed on proportional assist ventilation with load adjustable gain factors (PAV+) after at least 36 h on passive mechanical ventilation. PAV+ was continued for 48 h until the patients met pre-defined criteria either for switching to controlled modes or for breathing without ventilator assistance. ...
متن کاملNon-invasive proportional assist and pressure support ventilation in patients with cystic fibrosis and chronic respiratory failure.
BACKGROUND Patients with advanced cystic fibrosis can benefit from non-invasive positive pressure ventilation (NPPV) for the treatment of acute decompensation as well as for the management of chronic respiratory failure. This study was undertaken to compare the physiological effects of non-invasive proportional assist ventilation (PAV) and pressure support ventilation (PSV) on ventilatory patte...
متن کاملNew Modes of Ventilation: Proportional Assist Ventilation; Adaptive Support Ventilation; SmartCare
Introduction Proportional Assist Ventilation (PAV), Adaptive Support Ventilation (ASV) and SmartCare (SC) are new modes of ventilation that have recently become available on the market. Although these modes have numerous similarities, there are several important differences that clinicians should be aware of to ensure successful and appropriate application of each. The present paper will descri...

OBJECTIVE To compare the short-term physiologic effects of mask pressure support ventilation (PSV) and proportional assist ventilation (PAV) in patients in clinically stable condition with chronic ventilatory failure (CVF). DESIGN Randomized, controlled physiologic study. SETTING Lung function units of two pulmonary rehabilitation centers. PATIENTS Eighteen patients with CVF caused by COP...
