Study of Respiratory and Hemodynamic Variables in Patients Receiving either Volume Control Ventilation or Pressure Control Ventilation during Laparoscopic Surgeries

Year: 2026

Type: article

Abstract: Objective: To evaluate respiratory and hemodynamic variables in patients receiving volume-controlled ventilation (VCV) versus pressure-controlled ventilation (PCV) during laparoscopic surgeries. Methods: Sixty ASA grade I–II patients, aged 18–60 years, with a body mass index (BMI) under 30, scheduled for elective laparoscopic procedures, were enrolled. Group A was sustained on VCV, but Group B transitioned to PCV after 15 min of VCV. Ventilation parameters were established with a tidal volume of 6 mL/kg, a respiratory rate of 12 breaths per minute, and a PEEP of 5 cm H₂O. Hemodynamic and respiratory parameters (systolic and diastolic blood pressure (SBP, DBP), MAP, heart rate (HR), oxygen saturation (SpO₂), capnography (EtCO₂), and peak airway pressure (Ppeak)) were documented at intervals of 15 min. Results: Group A exhibited markedly elevated heart rate and mean arterial pressure (MAP) at multiple intervals ( P < 0.05). EtCO₂ levels were comparable between groups, except upon extubation, where Group B exhibited lower levels. Ppeak levels were significantly elevated with VCV after 30 min ( P < 0.001). Conclusion: PCV demonstrated reduced lower airway pressures and enhanced hemodynamic stability relative to VCV in non-obese ASA I–II individuals.
