Chapter 30-oxygenation Flashcards
(40 cards)
The movement of gases between air space and bloodstream?
Diffusion
The movement of air in and out of the lungs?
Ventilation
The exchange of oxygen and carbon dioxide?
Respiration
The movement of blood into and out of lungs to the organs and tissues of body?
Perfusion
Inadequate tissue oxygenation with a deficiency in oxygen delivery?
Hypoxia
Abnormal deficiency in the concentration of oxygen in arterial blood?
Hypoxemia
Ventilation is inadequate to meet the oxygen demands of the body, or to eliminate carbon dioxide?
Hypoventilation
Increase in respiratory rate, resulting in excess carbon dioxide elimination?
Hyperventilation
Resistance to the ejection of blood from left ventricle?
After load
Amount of blood at the end of ventricular diastole?
Preload
Stoke volume(SV) X heart rate(HR)=
Cardiac output (CO)
Ability of the heart to squeeze blood from the ventricles?
Myocardial contractility
Measure of adequacy of the cardiac output?
Cardiac index
Greater than normal carbon dioxide in the blood?
Hypercapnia
Collapsing of the alveoli?
Atelectasis
Chemical in lung that maintains the integrity of the alveoli?
Surfactant
Bloody sputum?
Hemoptysis
Necessary for patients receiving oxygen therapy at more that 4L/min?
Humidification
Aerosol principles to suspend max number of water drops of particles of desired size to air, usually in form of medication?
Nebulization
Mobilizes pulmonarybsecretions?
Chest physiotherapy (CPT)
Position techniques to drain secretions from specific segments of the lung?
Postural drainage
Striking of the chest wall over the area of lungs being drained?
Chest percussion
Fine, shaking pressure applied to chest wall only during exhalation?
Vibration
Catheter inserted through the rib cage into pleural space to remove air or fluids from the pleuropneumonia space and re-establish normal intrapleural and intrapulmonic pressure
Chest tube
