Level of health Considerations That Can Affect Oxygenation

- Acute and chronic illnesses - any disorders that affects that cardiovascular system affects oxygenation

Developmental Considerations That Can Affect Oxygenation

- Age related changes - Older adult: respiratory tract tissues and airways become less elastic - Power of respiratory and abdominal muscles is reduced - Diaphragm moves less efficiently - Blood vessels and valves become less efficient

Oxygenation of body tissues is dependent on...

- Airway System - Alveolar System - Cardiovascular System

Promoting Optimal Functioning: Avoid Pollution

- Dust & vacuum at home - avoid exposure to industrial or occupational hazards - wear a mask when exposure unavoidable - avoid cigarette smoke

Cough Medications

- Expectorants - Suppressants - Lozenges

Oxygenation Physical Assessment

- Inspection - Palpation - Percussion - Auscultation

Factors Affects Cardiopulmonary Functioning & Oxygenation

- Level of health - Medication considerations - lifestyle considerations - environmental considerations - psychological health considerations

Promoting Comfort

Oxygenation

- essential to life - demand for oxygen is met by cardiopulmonary system

Promoting Optimal Functioning: Maintain Good Nutrition
