factors affecting oxygenation
a. Decreased oxygen-carrying capacity
b. Hypovolemia
c. Decreased inspired oxygen concentration
d. Increased metabolic rate
e. Ineffective gas exchange (lungs)
f. Ineffective pump (heart)
Conditions Affecting chest wall movement
Pregnancy
Obesity
Musculoskeletal abnormalities
Trauma
Neuromuscular diseases
Central nervous system alterations
Influences of chronic lung disease
hypoventilation
Occurs when alveolar ventilation is inadequate to meet the oxygen demand of the body or eliminate
sufficient carbon dioxide
Hyperventilation
A state of ventilation in which the lungs remove carbon dioxide faster than it is produced by cellular
metabolism
Hypoxia
Low oxygen saturation of the body, not enough oxygen in the blood. A state of ventilation in which the
lungs remove carbon dioxide faster than it is produced by cellular metabolism
Early signs of hypoxia
Restlessness, elevated BP, tachypnea, tachycardia, pallor, pale mucous membranes
Late signs of hypoxia
Cyanosis, decreased LOC, behavior changes, confusion, stupor, bradypnea, bradycardia, low BP, cardiac
dysrhythmias
Alterations in Cardiac Functioning
disturbances in conduction, altered cardiac output, impaired valvular function, myocardial ischemia
, Left sided heart failure
1. Pnea, SOB
2. Crackles
3. Oliguria
4. Frothy Sputum
5. Displaced Apical Pulse (Hypertrophy)
Pulmonary edema
right sided heart failure
1. Jungular Vein Distention
2. Ascending Dependent Edema
3. Weight Gain
4. Hepatomegaly (Liver Enlargement)
Angina
Pain in the heart region caused by lack of oxygen. Partial obstruction
Myocardial infaction
Heart attack. Complete obstruction
occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart
muscle.The most common symptom is chest pain or discomfort which may travel into the shoulder, arm,
back, neck or jaw
Factors influencing oxygenation
- Developmental
- Lifestyle
- Environmental

d. Teach patient to take a deep breath, hold for a couple seconds, open mouth, tighten abd muscle,
cough 2-3 times with mouth open
e. Increase fluids to 2500ml for 24 hours, offer fluids patient prefers
