Term
| airway pressure release ventilation (APRV) |
|
Definition
| mode of mechanical ventilation that allows unrestricted, spontaneous breaths throughout the ventilatory cycle; on inspiration patient receives present level of continuous positive airway pressure, and pressure is periodically released to aid expiration |
|
|
Term
| assist-control ventilation (A/C) |
|
Definition
| mode of mechanical ventilation in which the patient's breathing pattern may trigger the ventilator to deliver a present tidal volume; in the absence of spontaneous breathing, the machine delivers a controlled breath at a preset minimum rate and tidal volume |
|
|
Term
|
Definition
| use of a chest tube and closed drainage system to re-expand the lung and to remove excess air, fluid, and blood |
|
|
Term
|
Definition
| manually cupping over the chest wall to mobilize secretions by mechanically dislodging viscous or adherent secretions in the lungs |
|
|
Term
| chest physiotherapy (CPT) |
|
Definition
| therapy used to remove bronchial secretions, improve ventilation, and increase the efficiency of the respiratory muscles; types include postural drainage, chest percussion, and vibration |
|
|
Term
| continuous positive airway pressure (CPAP) |
|
Definition
| positive pressure applied throughout the respiratory cycle to a spontaneously breathing patient to promote alveolar and airway stability; may be administered with endotracheal or tracheostomy tube or by mask |
|
|
Term
|
Definition
| mode of mechanical ventilation in which the ventilator completely controls the patient's ventilation according to preset tidal volumes and respiratory rate; because of problems with synchrony, it is rarely used except in paralyzed or anesthetized patients |
|
|
Term
|
Definition
| insertion of a breathing tube through the nose or mouth into the trachea |
|
|
Term
| fraction of inspired oxygen |
|
Definition
| concentration of oxygen delivered |
|
|
Term
|
Definition
| decrease in arterial oxygen tension in the blood |
|
|
Term
|
Definition
| decrease in oxygen supply to the tissues and cells |
|
|
Term
|
Definition
| method of deep breathing that provides visual feedback to help patients inhale deeply and slowly and achieve maximum lung inflation |
|
|
Term
| intermittent mandatory ventilation (IMV) |
