Breather Trainer Versus Pulmonary Rehabilitation on Cardiopulmonary Efficiency

Effect of Breather Trainer Versus Pulmonary Rehabilitation on Cardiopulmonary Efficiency in Patients With COPD Post COVID-19

The purpose of the study is to determine the difference between The Breather respiratory muscle trainer and pulmonary rehabilitation in patients with COPD post COVID-19.

The main concern in post COVID-19 patients is the involvement of respiratory system and cardiovascular system which may result in dyspnea, low blood oxygen saturation, and decrease cardiopulmonary efficiency.

In cases of post COVID-19 patients with COPD their state is deconditioned and more critical than normal to be either in the zone of progression or regression or stability as the studies showed that handling of these cases during (3-6 months post-COVID) will prevent these symptoms from becoming permanent.

Inclusion Criteria:

1. SPO2 ≥ 93%
2. Their age ranges from 30-40 years old.
3. COPD patients GOLD1 (Mild FEV1≥80% predicted) and GOLD2 (Moderate 50% ≤FEV1<80%predicted) (Manian, 2019)
4. patients diagnosed as post COVID-19 Pneumonia between 3 and 6 Months ago with CT scan and PCR testing.
5. Their body mass index (BMI) ranged from 20 to 29.9kg/m2.
6. Stable medical cases with dyspnea

Exclusion Criteria:

Patients who will meet one of the following criteria will be excluded from the study:

1. patients with cardiac problems e.g. atrial fibrillation, left bundle-branch block, heart failure.
2. Sever cases of COPD (FEV1/FVC< 50%)
3. Mitral or aortic valvular disease, pericardial effusion.
4. Recent myocardial infarction.
