Foundations of Nursing: Oxygenation

These flashcards cover key concepts from the Foundations of Nursing lecture on oxygenation, including respiratory and cardiovascular physiology, factors affecting oxygenation, and patient case studies.

What are the key components of respiratory physiology relevant to oxygenation?

Structure and function, work of breathing, lung volumes, pulmonary circulation.

What factors affect oxygenation?

Physiological factors, decreased oxygen-carrying capacity, hypovolemia, decreased inspired oxygen concentration, increased metabolic rate.

What are common conditions affecting chest wall movement?

Pregnancy, obesity, musculoskeletal abnormalities, trauma, neuromuscular diseases, central nervous system alterations, chronic lung disease.

List some alterations in respiratory functioning.

Hypoventilation, hyperventilation, hypoxia.

What are the main factors influencing cardiac output?

Heart rate and stroke volume.

What can cause disturbances in cardiac functioning?

Altered cardiac output, left-sided heart failure, right-sided heart failure, impaired valvular function, myocardial ischemia, angina, myocardial infarction.

What developmental considerations influence oxygenation in patients?

The normal aging process affects oxygenation across different age groups such as infants, toddlers, school-age children, adolescents, young and middle-age adults, and older adults.

How does lifestyle affect oxygenation?

Factors include nutrition, hydration, exercise, smoking, substance abuse, stress, and environmental factors.

Describe the role of critical thinking in assessing a patient’s oxygenation status.

Knowledge of cardiac and respiratory physiology and oxygen supply and demand ensures a logical approach to patient assessment.

What might John need to do when Mr. King is in respiratory distress?

He should prioritize providing immediate care to ease Mr. King’s breathing.

How can John approach the topic of smoking cessation with Mr. King?

He should discuss the benefits of quitting smoking during Mr. King's acute care visit, when he may be more receptive.
