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.

23 Typical transpulmonary driving pressure is roughly 5 to 10 cm H 2 O with normal spontaneous breathing in healthy individuals, 24 25 indicating the usual amount of global stress experienced across the lung in health. However, transpulmonary driving pressure can be substantially higher in patients with ARDS due to changes in compliance of the ...
static pressure–volume (PV) curve in patients with acute respira- tory distress syndrome (ARDS) indicates that some lung compart- ments do not initially receive insufflated gas.
19 Ιαν 1999 · The inspiratory limb of the quasi-static pressure-volume (P-V) curve of the total respiratory system has been used to guide mechanical ventilation in the acute respiratory distress syndrome (ARDS) (1, 2). The form of the curve is sigmoidal, with upward concavity at low inflation pressures and downward concavity at higher inflation pressures (3).
Equation 1 fitted equally well inflation and deflation P-V curves from normal, ARDS, and pneumoconstricted lungs (Figs.1-3) with mean goodness-of-fit coefficient (R 2) of 0.997 ± 0.02 (SE). Review of the fitted parameters revealed the following results.
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.
A 100-mL graduated syringe was used to inflate patients' lungs with 50- to 100-mL increments up to an airway pressure of 45 cm H 2 O or a total volume of 2 L; each volume step was maintained for 2 to 3 s until a plateau airway pressure was recorded.
