PULMONARY ASSESSMENT & VITAL MONITORING: Comprehensive clinical evaluation including breath sound auscultation, work of breathing, respiratory rate, and continuous pulse oximetry ($SpO_2$) profiling to detect airway compromise or respiratory distress.

AIRWAY CLEARANCE & CHEST PHYSIOTHERAPY: Implementation of postural drainage, percussion, vibration, and positive expiratory pressure (PEP) therapy techniques to mobilize secretions and prevent atelectasis.

RESPIRATORY DEVICE SETUP & CALIBRATION: Clinical titrations, compliance monitoring, mask fitting, and troubleshooting for CPAP, BiPAP, mechanical home ventilators, and oxygen concentrators.

TRACHEOSTOMY & SUCTION MANAGEMENT: Safe, sterile bedside endotracheal or tracheostomy tube care, inner cannula cleaning, stoma dressing, and deep airway secretion clearance.

PULMONARY REHABILITATION & PATIENT EDUCATION: Structured breathing retraining (pursed-lip, diaphragmatic exercises), aerosolized nebulizer medication administration techniques, and emergency action plan training for family caregivers.
