MCRT- A/W clearance

Key Terms

active cycle of breathing (ACB) airway clearance strategy consisting of repeated cycles of breathing control and thoracic expansion, followed by the forced expiratory technique
acute respiratory distress syndrome (ARDS) a respiratory disorder characterized by respiratory insufficiency and hypoxemia
autogeneic drainage (AD) modification of directed cough, beginning with a low lung volume breathing, inspiratory breath holds, and controlled exhalation, and progressing to increased inspired volumes and expiratory flows
bronchiectasis abnormal condition of the bronchial tree characterized by irreversible dilation and destruction of the bronchial walls
ciliary dyskinetic syndromes conditions in which respiratory tract cilia do not function properly
forced expiration technique (FET) modification of the normal cough sequence designed to facilitate clearance of bronchial secretions while minimizing the likelihood of bronchiolar collapse
high frequency chest wall compression (HFCWC) mechanical technique for augmenting secretion clearance; small gas volumes are alternately injected into and withdrawn from a vest by an air pulse generator at a fast rate, creating an a oscillatory motion against the patient’s thorax
hertz (Hz) a physical term meaning cycles per second
“huff” cough type of forced expiration with an open glottis to replace coughing when pain limits normal coughing
inspissation (of the fluid) thickened or hardened through a the absorption or evaporation of the liquid portion, as can occur with respiratory secretions when the upper airway is bypassed
intrapulmonary percussive ventilation (IPV) airway clearance technique that uses a pneumatic device to deliver a series pressurized gas mini bursts at higher rates to the respiratory tract, usually via a mouthpiece; usually combined with aerosol bronchodilator therapy
mucus plugging retention of secretions resulting in full or partial obstruction of the airway
oscillation back-and-forth motion; vibration or the effects of mechanical or electrical vibration
positive expiratory pressure (PEP) airway clearance technique in which the patient exhales against a fixed orifice flow resister in order to help move secretions into the larger airways for expectoration via coughing or swallowing
splinting process of immobilizing, restraining, or supporting a body part
venostasis disorder in which the normal flow of blood through a vein is slowed or halted
