mode of mechanical ventilation that allows unrestricted, spontaneous breaths throughout the ventilatory cycle; on inspiration patient receives preset level on continous postitive airway pressure, and pressure is periodically released to aid expiration

moed of mechanical ventilation in which the patient's breathing patterns may trigger the ventilator to deliver a preset tidal volume; in the absence of sppontaneous breathing, the machine delivers a controlled breath at a preset minimum rate and tidal volume

use of chest tube and closed drainage systems to re-expand the lung and to remove excess air, fluid, and blood

manually cupping over the chest wall to mobilize secretions by mechanically dislodging viscous or adherent secretions in the lungs

therapy used to remove bronchial secretions, improve ventilation, and increase the efficiency of the respiratory mscles; types include postural drainage, chest percussion, and vibration

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

mode of mechanical ventilation in which the ventilator completely controls the patient's ventilation according to present tidal volumes and respiratory rate; because of problems with synchrony, it is rarely used wxept in paralyzed or anesthetized patients

insertion of a breathing toube through the nose or mouth into the trachea

concentration of oxygen delivered (1.0 = 100% oxygen)

decrease in arterial oxygen tension in the blood

decrease in oxygen supply to the tissues and cells

method of deep breathing that provides visual feedback to help the patient inhale deeply and slowly and achieve maxium lung inflation

mode of mechanical ventilation that provides a combination of mechanically assisted breaths and spontaneous

a positive or negative pressure breathing device that supports ventilation and oxygenation

partial or complete collaps of the lung due to positive pressure in the pleural space

positive pressure maintained by the ventilator at the end of exhalation (instead of a normal zero pressure) to increase functional residual capacity and open collapsed alveoli; improves oxygenation with lower fraction of inspired oxygen

Postioning the patient to allow drainage from all the lobes of the lungs and airways

mode of mechanical ventilation in which preset positive pressure is delivered with spontaneous breaths to decrease work of breathing

mode of mechanical ventilation that provides partial ventilatory support in proportion to the patient's inspiratory efforts; decreases the work of breathing

process of gradual, systemic withdrawal or removal of ventilator, breathing tube, and oxygen

mode of mechanical ventilation in which the ventilator allows the patient to breathe spontaneously while providing a preset number of breaths to ensure adequate ventilation; ventilated breaths are synchronized with spontaneous breathing

surgical opening into the chest cavity

indwelling tube inserted directly into the trachea to assist with ventilation

surgical opening into the trachea

a type of massage administered by quickly tapping the chest with the fingertips or alternating the fingers in a rhythmic manner, or by using a mechanical device to assist in mobilizing lung secretions
