Summary

The investigators used transesophageal echocardiography (TEE) to assess the change of pulmonary blood flow and bi-ventricular function during lung isolation. The investigators hypothesized that changes in pulmonary venous flow with lung isolation may be related the shunt fraction and oxygenation during one lung ventilation (OLV). The investigators also observed the cardiac function during two lung ventilation (TLV) and OLV in supine and lateral position by TEE.

Conditions

• Video-assisted Thoracic Surgery

Interventions

Type	Name	Description
PROCEDURE	transesophageal echocardiography(TEE)	Transesophageal echocardiography examination will be performed TLV in supine and lateral position, 10, 20 and 30 min during OLV in left lateral decubitus position. By using the transesophageal echocardiography, we will evaluate the changes of pulmonary blood flow and cardiac function.
