Pulmonary Rehabilitation and Quality of Life in Children With Chronic Lung Diseases: A Multidisciplinary Approach

FEV₁ is the volume of air that a person can forcefully exhale in the first second of a forced breath after taking a deep inhalation.

Interpretation of FEV₁:

≥80% of predicted → Normal 60-79% of predicted → Mild obstruction 40-59% of predicted → Moderate obstruction <40% of predicted → Severe obstruction

FVC is the total volume of air that can be forcefully exhaled after taking the deepest possible breath.

Normal Values: Typically ≥80% of the predicted value. Obstructive Lung Disease: FVC may be normal or slightly reduced. Restrictive Lung Disease: FVC is significantly reduced due to decreased lung compliance or lung volume.

PEFR is the maximum speed of expiration achieved after full lung inflation. It is measured in liters per minute (L/min).

ormal values depend on age, sex, and height: Adult males: 450-700 L/min Adult females: 300-500 L/min Reduced PEFR: Suggests airway obstruction, such as in asthma or COPD.

Hospitalization frequency refers to the number of times a patient is admitted to a hospital due to disease exacerbation, complications, or treatment failure.

Number of hospital admissions within a specific time frame (e.g., per year). Length of hospital stay (days per admission). Emergency department visits requiring inpatient care.

Medication dependency refers to the extent to which a patient relies on pharmacological treatment to manage symptoms and maintain functional health.

Frequency and dosage of medication use. Number of rescue medication uses (e.g., bronchodilators in asthma). Reduction or discontinuation of medication over time.

Parental satisfaction refers to how parents perceive the effectiveness, convenience, and overall impact of their child's treatment plan.

Standardized satisfaction surveys (e.g., Likert scale questionnaires). Interviews or focus groups with parents. Feedback on treatment effectiveness, side effects, accessibility, and ease of use.
