    by: Monika

    Current Rating : Rate It :



    1 : Airway Clearance Techniques
    2 : Positioning/Repositioning Promotes mobilization of secretions, lung expansion, redistribution of ventilation, blood perfusion, and lymphatic flow 3/4 prone Prone Sitting upright Dangling: sitting on edge of bed Ambulation
    3 : Autogenic Drainage Mucus cleared during breathing exercises Coughing is avoided Slow, deep inspiration through nose Warms humidified air and prevents cough Breath hold for 2-3 seconds Exhale to ERV with open glottis but not to RV
    4 : Autogenic Drainage Phase 1 Peripheral unsticking of mucus Phase 2 Collection of peripheral and apical secretions Phase 3 evacuation
    5 : ERV RV TV IRV Phase 1 Phase 2 Phase 3
    6 : Active Cycle of Breathing Breathing control (BC) Relaxed tidal breathing Thoracic expansion exercise (TEE) Inhale from end TV to IRV, i.e., IC with or without breath hold f/by relaxed exhalation Forced expiratory technique (FET) Inhale to mid lung volumes f/by huff then inhale to higher lung volumes f/by huff
    7 : IRV TV ERV RV
    8 : Huff Forced expiratory manuever (FET) Low to mid lung volumes Forced expulsion of air with open glottis Lower turbulence and impedence to air flow Moves EPP more peripherally towards the alveoli to reduce airway compression
    9 : Cough Large lung volumes increases lung elastic recoil High intrathoracic pressure with glottic closure increases pleural pressure EPP moves downstream towards mouth resulting in high resistance to air flow on expulsion Intraluminal pressure < extraluminal pressure resulting in early airway closure
