pressure-controlled ventilation

pressure-controlled ventilation

mechanical ventilation that is achieved regardless of the patient's spontaneous breathing, but that uses pressure as the major determining variable, along with rate and time, of how much air the patient receives.

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 mode.

Pressure-controlled ventilation (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 [7].
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 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.
