What laboratory tests are recommended to develop a differential diagnosis?
The following laboratory tests are recommended to develop a differential diagnosis: chest x-ray, complete blood count, chemistry profile, electrocardiogram, and pulse oximetry at rest and with activity. • What kinds of exercise should be encouraged for COPD patients? Upper extremity training is important because arm movement can increase dyspnea. Simple weight training or other resistance exercises strengthen the upper arms, shoulders, and legs. Walking or riding a stationary bicycle improves endurance. Patients who have limited endurance or balance difficulties should not walk on a treadmill.

Pursed-lip breathing?intentionally exhaling through pursed lips for as long as possible?also reduces dyspnea and improves
