Predicting Oxygen Desaturation in Chronic Obstructive Pulmonary Disease (COPD) Patients

Composite Analysis on Factors That Predict Oxygen Desaturation During Walking in COPD

Oxygen desaturation (SO2 < 88-90%) during walking is a common clinical feature of Chronic Obstructive Pulmonary Disease (COPD) patients. By a predicted analysis our study is aimed to evaluate anthropometric and functional characteristics of COPD patients correlated with oxygen desaturation during Six-minute walking test (6MWT).

Inclusion Criteria:

• COPD patients
• Ability to perform 6MWT
• Normal oxygen saturation at rest and at the begin of 6MWT

Exclusion Criteria:

• No-COPD patients
• Chronic Respiratory Failure patients in Long-term oxygen therapy (LTOT)
• Any co-morbidities
