3. Spirometry is a test of lung function that measures how much and how quickly (volume and flow) the air movement in and out of the lungs. The measurements are made using an instrument called spirometer, which can provide the following parameters: i. Forced expiratory volume in one second (FEV1) ii. Forced vital capacity (FVC) These parameters can be used to make a diagnosis and to determine the severity of chronic obstructive pulmonary disease (COPD), an obstructive respiratory disorder characterized by airflow limitation and inflammation. It happens when the ratio of FEV1 to FVC is less than 0.70. The spirometric classification of COPD severity based on FEV1 is given in Table 5. Table 5. Spirometric classification of COPD severity. Condition / Severity Normal Mild COPD Moderate COPD Severe COPD Very severe COPD FEV1/ FVC > 0.70 FEV1 > 0.80 0.50 –- 0.79 < 0.70 0.30 - 0.49 <0.30 You are required to develop a program used by a medical practitioner to analyze the condition of few group…
