What is Oxygenation? Answer - Needed to sustain life
- Cardiac and respiratory systems function to supply the body's oxygen demand
What mechanisms are used in Oxygenation? Answer - Ventilation
Perfusion
Transport of Respiratory Gases
Ventilation Answer - Process of moving gases into and out of the lungs
Perfusion Answer - Relates to the ability of the cardiovascular system to pump
oxygenated blood --> tissues and return deoxygenated blood --> lungs
Atelectasis Answer - Collapse of alveoli that prevents normal gas exchange
between carbon dioxide and oxygen
Factors Affecting Oxygenation: Physiological Answer - - Decreased oxygen-
carrying capacity
- Decreased inspired oxygen concentration
- Hypovolemia
- Increased metabolic rate
, Factors Affecting Oxygenation: Conditions affecting chest wall movement
Answer - - Pregnancy
- Obesity
- Musculoskeletal Abnormalities
- Trauma
- Neuromuscular diseases
- CNS alterations
- Chronic diseases
Hyperventilation Answer - Excess ventilation to eliminate carbon dioxide
produced by cellular metabolism
- too much breathing
Hypoventilation Answer - Alveolar ventilation inadequate to meet body's
oxygen demand or to eliminate sufficient CO2
- breathing too less
Hypoxia Answer - Inadequate tissue oxygenation at the cellular level
Cyanosis Answer - Blue discolouration of skin and mucous membranes due to
insufficient oxygen
Hypovolemia Answer - Condition that occurs when your body looses too much
fluid (water or blood)
Nursing Management of Pts with Impaired Oxygenation Answer - 1. Promotion
of Lung Expansion
2. Management of Dyspnea
