Which term is defined as gravity-assisted drainage of secretions from the lungs and breathing techniques?

• A. Reverse T position
• B. Chest physical therapy
• C. Ischemia
• D. Seclusion

Answer: (B)

Gravity-assisted drainage of secretions from the lungs combined with breathing techniques is chest physical therapy. This approach uses postural drainage—placing the patient in specific positions so gravity helps secretions drain from particular lung areas into larger airways for easier coughing. Manual techniques like chest percussion or vibration loosen thick mucus, and breathing maneuvers plus coughing help move those secretions upward to be expelled. It’s used to clear airway mucus in conditions where secretions accumulate. The other terms don’t capture this whole therapeutic approach: ischemia is reduced blood flow, seclusion is isolation, and the reverse T position is just one drainage position rather than the full, technique-based method.
