Oxygenation Flashcards
Cardiopulmonary physiology
Provides oxygen to tissues and removes Co2 and waste products from the body
Oxygenation
Process by which oxygen is transported to the cells and carbon dioxide is transported from the cells
Ventilation
Movement of air in and out of the lungs
Diffusion
Movement of gases between air spaces and the bloodstream
Respiration
Exchange of oxygen and carbon dioxide during cellular metabolism
Movement of blood into and out of the lungs to the organs and tissues of the body and supported by the heart Ventilation Diffusion Respiration Perfusion
Perfusion
Need to get oxygen across
Alveolar membrane
Need to get oxygen into
Rbcs
Need to get oxygen into
Body cells
Inadequate tissue oxygenation with a deficiency in oxygen delivery at cellular level
Hypoxia
Hypoxemia
Hypoxia
Hypoxemia
Abnormal deficiency in concentration of oxygen in arterial blood. Low partial pressure of oxygen
Ventilation which is inadequate to meet demands of the body and results in hypercapnea. Respiratory acidosis
Hypo ventilation
Increase in respiratory rate which results in excess co2 elimination. Respiratory alkalosis
Hyperventilation
Clinical signs of hypoxemia
Dyspnea Tachypnea Restlessness motor function Anxiety mental status change Hyper or hypotension Pallor or cyanosis Blurred or tunnel vision Nausea and vomiting

The Manubrium and the body of the sternum
