Six-minute walking and pulmonary function test outcomes during the early period after lung cancer surgery with special reference to patients with chronic obstructive pulmonary disease.
To evaluate physical dysfunction during the early period after lung resection in patients with lung cancer and coexisting chronic obstructive pulmonary disease (COPD), we examined the relationship between the ratio of the forced expiratory volume in 1 second to the forced vital capacity (FEV1/FVC%) and the results of a 6-minute walk (6MW) test before and after surgery. ⋯ The decreases in 6MWD and SpO2 after surgery were significantly influenced by the preoperative FEV1/FVC%, but not by the decrease in VC. COPD patients have a limited capacity for walking during the early period after surgery due to significant oxygen desaturation.
