Study Notes

Oxygenation Basics

Oxygen is essential for sustaining life and energy production through chemical reactions in cells.
Cardiac and respiratory systems work together to meet the oxygen demands of the body through blood circulation.

Oxygenation Mechanisms

Blood oxygenation involves:
- Ventilation: Movement of gases in and out of the lungs.
- Perfusion: Delivery of arterial blood to capillary beds in tissues.
- Diffusion: Movement of oxygen from alveoli to capillaries based on concentration gradients.

Cardiac Output

Cardiac output refers to the volume of blood ejected from the left ventricle per minute, typically 4-6 liters.
Changes in circulating blood volume correspond with the body’s oxygen and metabolic needs.

Conduction System of the Heart

Organized electrical impulses control the heart's rhythm.
- Sinoatrial (SA) Node: The heart's natural pacemaker, generating impulses at 60-100 bpm.
- Atrioventricular (AV) Node: Relays impulses between atria and ventricles.

Nursing Assessment

Nursing History: Focus on the patient’s ability to meet oxygen needs.
Physical Examination: Includes head-to-toe observation of skin color, consciousness, breathing patterns, and chest wall movement.

Common Symptoms and Their Evaluation

Fatigue: Subjective loss of endurance, rated 1-10.
Dyspnea: Breathlessness indicating hypoxia, can be classified into physiological (exercise-related) or pathological (not related to activity).
Cough: Audible air expulsion; protective reflex to clear airway irritants; could be productive (with sputum) or nonproductive.
Wheezing: High-pitched sound due to narrowed airways, often associated with asthma.
Chest Pain: Requires evaluation of location, duration, and type; pleuritic pain is sharp and linked to inspiration.

Environmental Factors

Risks include exposure to cigarette smoke, pollutants, and occupational hazards like asbestos and fumes.
Family history of lung cancer and cardiovascular disease is relevant.

Diagnostic Tests

Exercise Stress Test: Assesses cardiac response to physical stress; reflects myocardial response to oxygen demands.
Pulmonary Function Test: Evaluates lung efficiency in gas exchange; utilizes a spirometer.
Arterial Blood Gas Tests: Assesses tissue oxygenation levels.
Oximetry: Provides noninvasive measurement of capillary oxygen saturation.
Chest X-ray: Helps observe lung fields for abnormalities.
Bronchoscopy: Visual examination allowing for biopsy and removal of obstructions.
Throat Cultures and Sputum Specimens: Identify respiratory pathogens.

Nursing Diagnoses

Common diagnoses include ineffective airway clearance, ineffective breathing pattern, and impaired gas exchange, often supported by specific symptoms.

Health Promotion Strategies

Vaccinations like the influenza and pneumococcal vaccines are important for preventing respiratory infections; ideal for older patients and those with chronic illnesses.
Environmental modifications aim to reduce exposure to irritants and promote safe behaviors, such as smoking cessation.
Encouraging hydration maintains respiratory mucous membrane moisture.
Breathing exercises (abdominal, diaphragmatic, pursed lip) help improve lung function and clear secretions.
Medications like cough suppressants and expectorants assist in managing respiratory symptoms.
