Ch. 40 Broncial Therapy - Resp. Ther. 2

Airway clearance strategy consisting of repeated cycles of breathing control and thoracic expansion, followed by the forces expiratory technique.

A respiratory disorder characterized by respiratory insufficiency and hypoxemia. Trigger include gram-negative sepsis, oxygen toxicity, trauma, pneumonia, and systematic inflammatory response.

Modification of directed coughing, beginning with low lung-volume breathing, inspiratory breath holds, and controlled exhalation, and progressing to increased inspired volumes and expiratory flows.

Abnormal condition of the broncial tree characterized by irreversible dilation and destruction of the bronchial walls.

Conditions in which respiratory tract cilia do not function properly.

Modification of the normal cough sequence designed to facilitate clearance of bronchial secretions while minimizing the likelihood of bronchiolar collapse.

Symbol for the physical term meaning cycles per second.

Mechanical technique for augmenting secretion clearance; injected into and withdrawn from a vest by an air-pulse generator at a fast rate, creating an oscillatory motion against the patient’s thorax.

Type of forced expiration with an open glottis to replace coughing when pain limits normal coughing.

(of a fluid) thickened or hardened through the absorption of evaporation of the liquid portion, as can occur with respiratory secretion when the upper airway is bypassed.

Airway clearance technique that uses a pneumatic device to deliver a series of pressurized gas minibursts at high rates (1.6 to 3.75 Hz) to the respiratory tract, usually via a bronchodilator therapy.

Retention of secretions resulting in full airway obstruction that can result in atelectasis and impaired oxygenation due to shunting.

Back-and-forth motion; vibration or the effects of mechanical or electrical vibration.

Airway clearance technique in which the patient exhales against a fixed orifice flow resistor in order to help move secretions into the larger airways for expectoration via coughing or swallowing.

Process of immobilizing, restraining or supporting a body part.

Disorder in which normal flow of blood through a vein is slow or halted.
