Volume-guaranteed Ventilation Versus Pressure-controlled Ventilation in Preterm Infants with Respiratory Distress Syndrome: A Randomized Controlled Trial
Background: This study was targeted toward comparing volume-guaranteed (VG) ventilation with conventional pressure-controlled (PC) ventilation in preterm infants with respiratory distress syndrome (RDS) in terms of the facilitation of weaning and extubation and occurrence of complications, such as pneumothorax, intraventricular hemorrhage (IVH), retinopathy of prematur...
متن کاملPressure-controlled ventilation and intrabronchial pressure during one-lung ventilation.
BACKGROUND Pressure-controlled ventilation (PCV) has been suggested to reduce peak airway pressure (P(peak)) and intrapulmonary shunt during one-lung ventilation (OLV) when compared with volume-controlled ventilation (VCV). At the same tidal volume (V(T)), the apparent difference in P(peak) is mainly related to the presence of a double-lumen tracheal tube. We tested the hypothesis that the decr...
متن کاملPressure controlled versus volume controlled ventilation with laryngeal mask airway.
STUDY OBJECTIVE To quantify the impact on peak airway pressure of pressure-controlled and volume-controlled ventilation during Laryngeal Mask Airway (LMA) use. DESIGN Prospective, crossover clinical study. SETTING University-affiliated hospital. PATIENTS 32 ASA physical status I and II patients undergoing general anesthesia with the LMA. INTERVENTIONS Patients were ventilated for three ...
متن کاملPressure-controlled ventilation improves oxygenation during laparoscopic obesity surgery compared with volume-controlled ventilation.
BACKGROUND We compared pressure and volume-controlled ventilation (PCV and VCV) in morbidly obese patients undergoing laparoscopic gastric banding surgery. METHODS Thirty-six patients, BMI>35 kg m(-2), no major obstructive or restrictive respiratory disorder, and Pa(CO(2))<6.0 kPa, were randomized to receive either VCV or PCV during the surgery. Ventilation settings followed two distinct algo...
متن کاملComparison of pressure-controlled ventilation with volume-controlled ventilation during one-lung ventilation: a systematic review and meta-analysis
BACKGROUND Not only arterial hypoxemia but acute lung injury also has become the major concerns of one-lung ventilation (OLV). The use of pressure-controlled ventilation (PCV) for OLV offers the potential advantages of lower airway pressure and intrapulmonary shunt, which result in a reduced risk of barotrauma and improved oxygenation, respectively. METHODS We searched Medline, Embase, the Co...
