Brief summary

The purpose of this clinical trial was to understand the effects of variable tidal volume ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (C-VCV), pressure-controlled ventilation (PCV), and open surgery (Open Surgery). controlled ventilation (C-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (C-VCV), and pressure-controlled ventilation (PCV) for open surgery, video-assisted thoracoscopic surgery, and segmental lung resection. VATS), segmentectomy (Segmentectomy), lobectomy (Lobectomy), and pneumonectomy (Pneumonectomy) on oxygen saturation and pulmonary complications, and length of hospitalization. The main question it aims to answer is: variable tidal volume ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (C-VCV), and pressure-controlled ventilation (PCV).Does it decrease patient oxygen saturation, and does it increase pulmonary complications, length of hospitalization? Researchers compared variable tidal volume ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (C-VCV), and pressure-controlled ventilation (PCV) to compare them to see which mode of ventilation has the least physiologic disruption for the patient. Participants will: Select the appropriate surgical procedure according to the condition and be randomized to variable tidal volume ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume- controlled ventilation (C-VCV), pressure-controlled ventilation (PCV), and were checked after surgery. Patients' oxygen saturation, pulmonary complications, length of hospitalization were recorded

Interventions

The initial tidal volume was set at 6-8 ml/kg IBW according to the Ideal Body Weight (IBW).The maximum tidal volume (Vt\_max) and minimum tidal volume (Vt\_min) were set at 10-20% of the basal tidal volume (Vt\_base). Respiratory Rate 12. Inspiratory Flow Rate (IFR) 60L/min, Inspiratory to Expiratory Ratio (IER) 1:2, Positive End-Expiratory Pressure (PEEP) 5cm water column, and Inhaled Oxygen Concentration (FiO2) 41%.

The initial tidal volume was set at 6-8 ml/kg IBW according to the Ideal Body Weight (IBW), the upper limit of peak inspiratory pressure was 30 cmH2O, the maximum tidal volume (Vt\_max) and the minimum tidal volume (Vt\_min) was set at 10-20% of the base tidal volume (Vt\_base). Respiratory Rate is 12, Inspiration to Expiration Ratio is 1:2, Positive End-Expiratory Pressure (PEEP) is 5cmH2O, and Inhaled Oxygen Concentration (FiO2) is 98%.
