Study Notes
Altered Respiratory Function
- Common respiratory conditions: COPD, Asthma, Emphysema, Tuberculosis, Pneumonia, Sinusitis, Upper Respiratory Infections (URI).
Anatomy and Physiology
- Upper and lower respiratory tracts are essential for gas exchange and airflow regulation.
Upper Respiratory Airway
- Critical for filtering, warming, and humidifying inhaled air.
- Includes the nasal cavity, pharynx, and larynx.
Lower Respiratory Airway
- Comprises the trachea, bronchi, and bronchioles leading to alveoli for gas exchange.
Etiology (Causes)
- Infection (viral/bacterial), allergens, environmental irritants, and lifestyle factors contribute to respiratory diseases.
Medications
- Antihistamines: Reduce acute symptoms like itching and nasal secretions; do not alleviate congestion.
- Decongestants: Induce vasoconstriction to relieve nasal congestion; can raise blood pressure and heart rate.
Influenza
- Seasonal viral infection causing fever, cough, sore throat, and body aches.
Sinusitis
- Inflammation of sinus cavities leading to nasal obstruction, facial pain, and purulent nasal discharge.
Pharyngitis
- Bacterial causes include Group A Streptococcus associated with fever and swollen lymph nodes.
- Viral causes result in symptoms like red pharynx and clear nasal discharge.
Lower Respiratory Problems
- Affected by infections (pneumonia, tuberculosis), chronic conditions (COPD), and obstructive diseases (asthma).
Tuberculosis
- Contagious bacterial infection primarily affecting the lungs, characterized by persistent cough and weight loss.
Obstructive Pulmonary Disease (COPD and Asthma)
- Asthma: Chronic inflammatory disorder of the airways causing wheezing, breathlessness, and reversible airflow obstruction.
- COPD: Primarily caused by cigarette smoking, leading to chronic bronchitis and emphysema.
COPD Complications
- Polycythemia Vera: Increased hemoglobin due to chronic hypoxia.
- Cor Pulmonale: Right heart failure from pulmonary hypertension; significant symptom includes dyspnea.
Oxygen Therapy
- O2 therapy is critical for treating COPD and hypoxemia; it enhances blood oxygen levels.
Flow Delivery Methods for Oxygen
- Low Flow: Nasal cannula and simple face mask; safe and effective for patients with mild to moderate needs.
- High Flow: Nasal cannula and non-rebreather masks; capable of delivering a higher concentration of O2 for critically ill patients.
Nursing Interventions
- Monitor patient responses to oxygen therapy, ensuring equipment fits well and is functioning correctly.
- Provide adequate humidification to prevent drying of airways, especially in higher flow scenarios.
Asthma Risk Factors
- Allergens, pollutants, respiratory infections, and genetic predisposition can exacerbate symptoms.
Assessment and Diagnostics
- Assess lung function through spirometry and symptom history; chest X-rays may also be utilized for diagnosis.
COPD Interventions
- Focus on smoking cessation, bronchodilator therapy, and pulmonary rehabilitation programs.
