Group L – low flow group, Group N – normal flow group. T₀ – before anesthesia, T₁ – 10 min after intubation, T₂ – 5 min before insufflation of CO₂, T₃ – 5 min after insufflation of CO₂, T₄ – 5 min after reverse Trendelenburg position, T₅ – 5 min after supine position, T₆ – 5 min after desufflation of CO₂, T₇ – 15 min after awakening from anesthesia.
