It is increasingly recognized that the benefits of LPV are not just limited to the critical care setting. Indeed, it is associated with improved mortality and ventilator-free days. LPV is thought to reduce ventilator-associated lung injury via minimizing atelectotrauma, barotrauma, volutrauma and biotrauma. Its use is established in patients with Acute Respiratory Distress Syndrome (ARDS), with the ARDSnet trial being of particular significance. Lung Protective Ventilation (LPV) refers to a ventilatory strategy comprising of measures including relatively low tidal volumes (TV) of 6-8 ml/kg of Ideal Body Weight (IBW) accompanied by Positive End Expiratory Pressure (PEEP) and use of alveolar recruitment maneuvers. This may be addressed through formal, protocolized intraoperative ventilation setting. Conclusion: There is an association between female gender, obesity and excessive tidal volume ventilation. In contrast, the urgency and length of surgery, the choice of airway devices and the mode of ventilation were not associated with excessive ventilation. Results: Obesity and gender are independently associated with risk of excessive ventilation. Potential risk factors for excessive tidal volume ventilation were assessed using univariable and multivariable regression models. Methods: We conducted a post-hoc analysis using data from a recent clinical audit on departmental ventilation practices. ![]() With Postoperative Pulmonary Complications (PPCs) contributing towards significant morbidity and mortality following surgery, evidence indicates that effective use of LPV measures intraoperatively has been associated with reduced rates of PPCs. ![]() This includes: delivering tidal volumes of 6-8 ml/kg of ideal body weight, use of positive end expiratory pressure and recruitment maneuvers. Background: Lung Protective Ventilation (LPV) refers to a combination of measures aimed at reducing ventilator-associated lung injury.
