|---|---|
| Cystic Fibrosis Pathophysiology | Autosomal recessive disorder. Defect in CFTR protein leads to thick, sticky mucus in lungs and pancreas. Results in chronic infection, inflammation, and progressive lung damage. |
| Chest Physiotherapy (CPT) | Includes postural drainage, percussion, vibration. Goal is to mobilize secretions from peripheral airways to central airways for expectoration. |
| Bronchodilators in CF | Often used before CPT to open airways. Common drug: Short-acting beta-agonists (SABAs) like albuterol. |
| Airway Clearance Techniques | Hierarchy: Open airway first (meds), then mobilize secretions (CPT), then expect/have patient cough. Hydration supports overall thinning. |
| Intervention | Purpose & Timing | Why It's Not the *Immediate* Priority Here |
|---|---|---|
| Administer Bronchodilator | To dilate airways before CPT, making secretion removal more effective. Directly prepares for the ordered therapy. | This IS the priority. It's the preparatory step that maximizes the benefit of the critical intervention (CPT). |
| Increase Fluid Intake | Long-term systemic hydration to thin secretions. Vital for daily management. | Effect is delayed (hours). Does not immediately improve the efficacy of the next CPT session. |
| High Fowler's Position | Supportive measure to ease breathing by reducing pressure of abdominal contents on diaphragm. | Passive. Does not actively clear the obstructing secretions causing the hypoxemia. |
