Design outcomes

Primary

Measure	Time frame
7th day after surgery the pressure expiratory maximum	—

Secondary

Measure	Time frame
incidence of postoperative pulmonary complications, respiratory function (peak cough flow, pressure inspiratory maximum, peak expiratory flow, vital capacity (VC), % VC, %forced expiratory volume in one second (FEV1), FEV1/FVC, swallowing function (The Food Intake LEVEL Scale, repetitive saliva swallowing test), progression of post-operative rehabilitation (initiation days of sitting edge of bed, standing, and walking)	—
