Comparison of volume-controlled and pressure-controlled ventilation
in steep Trendelenburg position for robot-assisted laparoscopic radical prostatectomy.
(PCV) has inspiratory pressure and respiratory frequency as constant parameters, while the tidal volume achieved depends on lung compliance and resistance.
When using a classical LMA, pressure-controlled ventilation
is preferred to volume-controlled ventilation to decrease gastric insufflation .
For patients receiving assist/control ventilation (A/C), volume-controlled ventilation (VCV), pressure-controlled ventilation
(PCV), and pressure-regulated volume control ventilation (PRVC), the V[sub]T under mandatory ventilation was adapted; for patients receiving biphasic positive airway pressure (BIPAP), the V[sub]T under the high-level pressure was recorded; for patients receiving pressure support ventilation (PSV) and continuous positive airway pressure (CPAP), the V[sub]T of monitoring was adapted; and for patients receiving synchronized intermittent mandatory ventilation (SIMV) combined with PSV, the V[sub]T under mandatory ventilation and pressure support were both recorded and the larger of the two values was adapted.
The results of study was pressure-controlled ventilation
resulted in a significant decrease in (mean [+ or -] SD) peak airway pressure at 10 min was 20.
2]O; if this value was exceeded, volume-controlled ventilation was changed to pressure-controlled ventilation
25 despite several hours of attempting to improve oxygenation by conventional volume ventilation, optimized positive end-expiratory pressure (PEEP), recruitment maneuvers, pressure-controlled ventilation
, prone positioning, and high-frequency oscillatory ventilation.
Although pressure-controlled ventilation
has been the traditional mode of ventilation in neonates it is often associated with [V.
Among the new types of ventilation that have become common place is variable-flow, time-cycled, pressure-controlled ventilation
All patients were transferred to the intensive care unit (ICU) and pressure-controlled ventilation
was initiated with Fi[O.
During a pressure-controlled ventilation
breath, the TI is directly set by the RCP.
Satisfactory airway management suitable for the duration of anaesthesia was assessed by 1) observation of bilateral, symmetrical chest wall movement, 2) a square-wave capnograph trace and 3) clinically relevant leak-free ventilation (defined as an ability to inflate the lungs with pressure-controlled ventilation
set to deliver a tidal volume of at least 6 ml.
