Asthma Exacerbation Management
- Next step: Administer 100% oxygen to a patient experiencing asthma exacerbation.
Asthma vs. COPD
- Distinguishing features: COPD typically affects older smokers, while asthma can affect individuals of any age, often with a history of allergies.
- COPD: typically presents with irreversible airflow obstruction, while asthma is characterized by reversible airflow obstruction.
- COPD: commonly associated with chronic cough, dyspnea, and wheezing.
- Asthma: often triggered by allergens, irritants, or exercise.
Exercise-Induced Cough
- Management: If a young non-smoker patient presents with exercise-induced cough and normal pulmonary function test (PFT) results, consider further investigation for alternative causes, such as vocal cord dysfunction, exercise-induced bronchospasm, or other respiratory conditions.
Oxygen Administration for Asthma Exacerbation
- Next step: After administering 100% oxygen to a patient with asthma exacerbation, assess the patient's response and administer nebulized bronchodilators.
- Monitoring: Monitor the patient's respiratory status, including oxygen saturation levels, pulse rate, and breath sounds.
FEV1/FVC Ratio and Bronchodilator Administration
- Improved FEV1/FVC ratio: An improved FEV1/FVC ratio after bronchodilator administration suggests reversible airflow obstruction, which is a hallmark of asthma.
