A size 2.5 uncuffed endotracheal tube was used, and pressure-controlled ventilation
was preferred to adjust the end-tidal carbon dioxide values between 30 and 35 mmHg of both twins.
Objective: The aim of this study is to use stroke volume variation (SVV) as an indicator to predict fluid responsiveness in patients undergoing protective one-lung ventilation (OLV) in pressure-controlled ventilation
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.
She was ventilated by pressure-controlled ventilation
, volume-guaranteed mode (PCV-VG[R], GE Healthcare, Little Chalfont, England) at a tidal volume (TV) of 450 mL, respiratory rate of 12breaths/min, positive end-expiratory pressure (PEEP) of 5 cm[H.sub.2]O, and upper limit of peak inspiratory pressure (PIP) of 30 cm[H.sub.2]O, with 50% oxygen.
Then, guaranteed volume, pressure-controlled ventilation
was established and we maintained the end-tidal C[O.sub.2] (ETC[O.sub.2]) levels at 35mmHg with tidal volumes (TV) of 350 ml and a respiratory rate of 15/min.
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 20.4[+ or -] 2.7 vs 24.0 [+ or -] 4.7 cmH2O, (p=0.004) and 30 min 20.7 [+ or -] 3.0 vs 23.9 [+ or -] 4.9 cmH2O, (p=0.015).

to rest respiratory muscles improve sleep in ICU patients?" Respiratory Medicine, vol.
The PV group received Fi[O.sub.2] 0.5, PEEP 5 cm[H.sub.2]O and pressure-controlled ventilation
, and pressure was adjusted to achieve a [V.sub.T] reading of 6 ml/kg body weight.
ECMO was considered for patients with a PaO2/FiO2 ratio < 85 mmHg and/or respiratory acidosis with a pH < 7.25 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.
