Study Notes
Respiratory Emergencies Key Concepts
-
Hypoxic Drive: In patients with chronic respiratory conditions, breathing is primarily stimulated by low oxygen levels in the blood (hypoxic drive).
-
Pulmonary Gas Exchange: Effective gas exchange requires that oxygen and carbon dioxide can easily diffuse across the alveolar-capillary membrane.
-
Viral Infections in Children: A 3-year-old with severe shortness of breath, cough, cold, and fever is likely experiencing a viral infection of the upper respiratory tract.
-
Anaphylaxis Management: In cases presenting with acute shortness of breath, hives, and facial swelling, epinephrine is crucial alongside high-flow oxygen.
-
Auscultation Findings: Low-pitched "rattling" sounds at lung bases indicate aspiration pneumonia.
-
CPAP Contraindications: Continuous positive airway pressure (CPAP) is contraindicated in patients with shortness of breath and severely low blood pressure.
-
Lung Sound Assessment: Lung sounds are essential for every respiratory patient assessment.
-
Pleural Effusion Definition: A pleural effusion is characterized by fluid accumulation outside the lung.
-
Asthma Pathophysiology: Asthma results from immune system responses leading to airway obstruction and inflammation.
-
Crackles (Rales): These sounds occur due to air passing through fluid in the lungs.
-
Cystic Fibrosis: This genetic disorder makes patients prone to frequent lung infections.
-
Spontaneous Pneumothorax Indicators: A patient with emphysema and acute dyspnea following a cough may have a spontaneous pneumothorax, evident by diminished breath sounds.
-
PASTE Assessment Tool: "PASTE" is an assessment tool for evaluating respiratory patients.
-
Inhaler Use in Asthma: After using a metered-dose inhaler, patients should hold their breath to maximize medication absorption.
-
Tuberculosis Symptoms: Symptoms like chronic cough, green sputum, and night sweats may indicate tuberculosis, especially in immunocompromised patients.
-
Hypoxia Risk Factors: Severe anxiety is least likely to result in hypoxia compared to conditions like narcotic overdose or pulmonary edema.
-
Adventitious Lung Sounds: The presence of adventitious sounds suggests abnormal lung conditions.
-
Characteristics of Adequate Breathing: Adequate breathing is characterized by a respiratory rate of around 24 breaths per minute with equal breath sounds and normal skin color.
-
Respiration Site: Primary respiration occurs in the alveoli where gas exchange happens.
-
Bronchiolitis Identification: Signs of decreased air entry and wheezing in a young child with a recent chest infection may indicate bronchiolitis, often associated with respiratory syncytial virus (RSV).
