21 Ιουν 2001 · The presence of an initial segment with a low compliance on the static pressure–volume (PV) curve in patients with acute respiratory distress syndrome (ARDS) indicates that some lung compartments do not initially receive insufflated gas.

On this pressure–volume graph, compared with curve B, curve A illustrates a patient with increased respiratory system compliance and as a result at a given tidal volume there is reduced driving pressure.
Where mechanical ventilation is required, the use of low tidal volumes (<6 ml/kg ideal body weight) and airway pressures (plateau pressure <30 cmH2O) was recommended. For patients with moderate/severe ARDS (PF ratio<20 kPa), prone positioning was recommended for at least 12 hours per day.
10 Αυγ 2006 · The pressure–volume (PV) curve is a physiological tool proposed for diagnostic or monitoring purposes during mechanical ventilation of acute respiratory distress syndrome.
22 Ιαν 1998 · Measuring elastic pressure–volume (Pel-V) curves of the respiratory system and the volume recruited by a positive end-expiratory pressure (PEEP) allows one to study the pressure range over which recruitment occurs in acute lung injury (ALI), and to explain how recruitment affects the compliance.
The reduction in linear compliance measured by the PV curve is considered a hallmark of ARDS and is usually explained chiefly by the loss of aerated lung volume. Lung areas with a normal appearance on plain radiograph scans, however, show increases in lung tissue despite preserved aeration on computed tomography images, indicating that lung ...
Mild: 200 mm Hg < Pao2/Fio2 ratio ≤ 300 mm Hg with positive end-expiratory pressure (PEEP) or continuous pos-itive airway pressure ≥ 5 cm H2O. Moderate: 100 mm Hg < Pao2/Fio2 ratio ≤ 200 mm Hg...
