One-lung Ventilation

One-lung ventilation (OLV) is the method of separating one lung from another and each lung functions independently by preparing the airways. OLV used for the protection of healthy lung from damaged lung, diversion of ventilation from infected airway or lung, and Improved exposure of surgical field. OLV causes hypoxemia during endoscopic transthoracic sympathectomy, more damage, significant physiologic change & easily develops hpoxaemia. OLV is commanly used in cardiothoracic surgery, and the the key equipment for OLV is Flexible Fiberoptic Bronchoscopy (FOB). Systemic hypoxemia is a greater problem occurs during OLV, because of CO2 is higher than normal level of upto 20 times more diffusible than O2 and Pa CO2 is more depender on ventilarion compared with PaO2 which is more dependent on perfusion. Methods of Lung separation: There are so many methods widely used for OLV based on indications, patient factors, type of equipment, skills, experience, and practice. Below listed few methods, • Double-lumen endotracheal tube, DLT • Single-lumen ET with a built-in bronchial blocker, Univent Tube • Single-lumen ET with an isolated bronchial blocker • Arndt (wire-guided) endobronchial blocker set • Balloon-tipped luminal catheters • Endobronchial intubation of a single-lumen ET Lung isolation can be successful in all patients when One-lung ventilation could be accomplished within 15 min.
