Unit 5 Respiratory Flashcards
Hypoventilation
Occurs when alveolar ventilation is inadequate to meet the body’s demand or to eliminate sufficient to co2.
Hyperventilation
State of ventilation in excess of that required to eliminate the the normal venous CO2 produced by cellular metabolism.
Hypoxia
Is inadequate tissue oxygenation at the cellular level. Can result from deficiency in o2 delivery or o2 utilization.
Atelectasis
Is a collapse of the alveoli that prevents normal respiratory exchange of o2 and co2.
Diaphragmatic Breathing
Requires patients to relax intercostal and accessory respiratory muscle while taking deep inspirations
Pneumothorax
Collection of air in the pleural space.
Hemothorax
An accumulation of blood and fluid in the pleural cavity between parietal and visceral pleurae, usually results from trauma.
Postural drainage
Use of positioning techniques that draw secretions from specific segments of the lungs and bronchi into the trachea.
Pursed Lip Breathing
Involves deep inspiration and prolonged expiration through pursed lips to prevent alveolar collapse.
Dyspnea
Clinical sign of hypoxia and manifests as breathlessness. Difficult or uncomfortable breathing.
Orthopnea
Difficulty breathing when lying down.
Wheezing
Characterized by high pitched musical sounds caused by high velocity movement of air though a narrow airway.
Hemoptysis
Bloody sputum, reported with coughing and bleeding form the URT from sinus drainage.
Cyanosis
Blue discoloration of the skin and mucous membranes.
Unilateral Lung Disease
O2 sat increases with good side down, side lying position.
