Cardio-respiratory physiology during one-lung ventilation: complex interactions in need of advanced monitoring

摘要

During thoracic surgery, patients are often positioned on the lateral decubitus with the surgical site exposed, while gas exchange is granted through one-lung ventilation (OLV) technique. OLV is widely used to selectively ventilate the dependent lung, while the non-dependent one is collapsed to facilitate surgery. Careful settings of OLV can be extremely challenging as they have multiple and sometimes conflicting goals. To better understand challenges of OLV, changes induced in patients’ physiology should be understood thoroughly.
