Initial Impression: Acute Asthma Exacerbation
Justification for F2 Classification:
- Patient is experiencing severe respiratory distress with rapid onset
- Use of accessory muscles, wheezing, and inability to speak in full sentences are signs of significant respiratory compromise
- Time-sensitive condition requiring prompt medical intervention to prevent respiratory failure
Differential Diagnoses:
1. Acute Asthma Exacerbation (high probability)
2. Acute Bronchitis (less likely given patient's history and rapid onset)
3. Pneumonia (less likely given lack of fever and specific symptoms)
4. Anaphylaxis (less likely given lack of allergy triggers and other symptoms)
5. Pulmonary Embolism (lower probability, no risk factors mentioned)
Required Actions:
- Dispatch of ground EMS with ALS capabilities
- Immediate oxygen administration
- Bronchodilator therapy (nebulized salbutamol) initiation
- Corticosteroid administration (IV or oral)
- Preparation for transport to nearest hospital with respiratory support
Final Diagnosis: Severe Acute Asthma Exacerbation
Key Findings:
- Patient’s SpO2 was 88% on room air, improved to 94% with supplemental oxygen.
- Significant wheezing and use of accessory muscles were observed during assessment.
- Peak expiratory flow rate (PEFR) was severely reduced.
- Chest X-ray ruled out other causes of respiratory distress.
Outcome validated F2 priority assignment. Rapid dispatch and appropriate interventions were critical. Patient required nebulized bronchodilators and intravenous corticosteroids in the emergency department. Patient was admitted for observation and respiratory support.
Learning Points:
1. F2 classification was appropriate due to the severity of the respiratory distress.
2. Prompt recognition of severe asthma exacerbation and rapid intervention were crucial for positive outcome.
3. Patient's history of asthma and use of inhalers should have prompted earlier intervention by the patient.
