Study Notes
Oxygenation
- Oxygen is vital for survival, essential for cellular function
- The respiratory system delivers oxygen and removes carbon dioxide
- Normal oxygenation involves proper ventilation and circulation
- Oxygenation refers to how effectively tissues receive oxygen
Normal Oxygenation Process
- Inspired air enters the lungs
- Oxygen moves from alveoli to the blood (pulmonary capillaries)
- Carbon dioxide moves from blood to alveoli
- Oxygenated blood circulates to tissues
- Cells use oxygen; carbon dioxide is released
Physiology of Respiration
- Ventilation ensures air movement in and out of lungs
- Oxygenation is crucial for cells receiving oxygen
- Gas exchange in alveoli depends on factors like:
- Airway integrity
- Functional alveolar system
Mechanism of Ventilation
- Inhalation: Chest cavity expands, reducing pressure, drawing air in
- Exhalation: Diaphragm and intercostal muscles relax, increasing pressure, forcing air out
Process of Oxygenation
- Ventilation: Moving air into and out of lungs
- Perfusion: Cardiovascular system transporting oxygenated blood to tissues
- Diffusion: Exchange of gaseous substances in alveoli and capillaries (external respiration)
- External Respiration: Exchange in alveoli
- Internal Respiration: Exchange in capillaries and tissues
Factors Affecting Oxygenation
- Physiological factors (e.g., metabolic rate)
- Disease processes (e.g., anemia, dehydration)
- Environmental factors (e.g., high altitudes)
- Factors affecting chest wall movement (e.g., trauma)
- Pregnancy
- Musculoskeletal abnormalities
- Medications
- Lifestyle factors (e.g., smoking)
Common Respiratory Alterations
- Hyperventilation: Increased breathing rate and depth
- Hypoventilation: Inadequate breathing rate and depth
- Hypoxia: Inadequate tissue oxygenation
- Hypoxemia: Inadequate blood oxygenation
- Altered breathing patterns (e.g., tachypnea, bradypnea, apnea)
- Obstructed airways
Nursing Interventions
- Airway management: Humidified air or immediate oxygen administration; monitoring
- Monitor respiratory status and oxygenation
- Administering medications (e.g., bronchodilators )
- Auscultate lungs for sounds (before and after treatment)
- Encourage deep breathing, coughing
Respiratory Monitoring
- Observe rate, rhythm, depth and effort of breathing
- Monitor changes in oxygen saturation and arterial blood gas values
- Note any restlessness, anxiety, or air hunger
Anxiety Reduction
- Calming and reassuring behaviors
- Staying with the patient
- Encouraging slow breathing techniques (e.g., pursed lips)
Teaching
- Patient education about the disease process and medication
- Preventing adverse effects of treatment
- Evaluate patient's medication self-administration skills
- Involve family/significant others in the process
