B260 Fundamentals: Final Review with Complete
Solutions Oxygenation - Correct Answer Ventilation - Correct Answer process of getting O2 in and out of lungs Perfusion - Correct Answer Getting oxygenated blood to tissue Diffusion - Correct Answer Process of exchanging gas in the alveoli and capillaries of the body tissues.Intrapeular space is... - Correct Answer negative and becomes more negative in order Stroke volume is affected by.... - Correct Answer 1. preload
- after load (resistance to left ventricle)
- contractility
- Hypovolemia (dehydration and hemorrhage)
- Decreased inspired oxygen concentration (high altitudes)
- Increased metabolic rates (Fever)
- Kyphosis/Pectus excavatum
- Trauma
- Obesity
- Trauma
- Neuromuscular disease
- CNS alterations
- Chronic disease (COPD) 1 / 2
Physiological factors affecting oxygenation - Correct Answer 1. Decreased oxygen-carrying capacity (anemia)
Factors affecting chest wall movement - Correct Answer 1. Pregnancy
Hypoventilation - Correct Answer Respiration rate is low and depth is low CO2 is accumulating Hyperventilation - Correct Answer Ventilation is in excess (removing too much CO2) Rate and depth are increased Which is NOT a cause for hyperventilation?Fever Atelectasis Drugs Anxiety - Correct Answer Atelectasis Hypoventilation causes - Correct Answer Atelectasis and collapsed alveoli Hyperventilation causes - Correct Answer Anxiety Drugs Fever Acid/Base imbalance infection
Hypoxia causes: - Correct Answer 1. Decreased Hgb (carrying capacity)
- Impaired diffusion (pneumonia)
- Diminished O2 inspired
- Impaired ventilation
- O2 via nc (up to 6 lpm)
- Incentive spirometry
- Cough
- Liquids
- / 2
Oxygenation interventions - Correct Answer 1. Raise HOB
