Treatment of Acute Eosinophilic Pneumonia When Respiratory Rate Is ≤30 Breaths/Min (No Respiratory Failure)
This protocol applies to patients with acute eosinophilic pneumonia who present without respiratory failure — defined as a Pa,O2/FI,O2 ratio above 300 with no tachypnea and a respiratory rate at or below 30 breaths per minute.
Clinical Scenario
Respiratory rate ≤30 breaths/min · No tachypnea
The treatment strategy for acute eosinophilic pneumonia is stratified by the presence or absence of respiratory failure. This protocol is indicated when the patient does not meet the respiratory failure threshold: Pa,O2/FI,O2 ratio is greater than 300 and the respiratory rate remains at or below 30 breaths per minute.
Treatment Approach (Partial Overview)
In the absence of respiratory failure, management is guided by an oral corticosteroid regimen. The specific agent and schedule are defined in the full structured protocol.
Complete dosing, sequencing, and monitoring details are available via the protocol link below.
Expected Clinical Goals
- Defervescence within 48 hours
- Improvement of dyspnoea within 3 days
- Resolution of all symptoms within a median of 7 days
- Disappearance of pulmonary infiltrates on chest radiograph within 7 days

The attending physician chose a regimen based on the presence of respiratory failure defined as a Pa,O2/FI,O2 ratio <300 and/or tachypnea (respiration rate >30 breaths·min-1).
When the patient had no respiratory failure, 30 mg oral prednisolone was administered twice a day (fig. 1).
All symptoms improved after a median of 7 (4–10) days; defervescence occurred within 48 h in all patients and dyspnoea was improved within 3 (2–5) days.
In addition, the majority of pulmonary infiltrates on chest radiographs disappeared within 7 days after corticosteroid treatment, which is consistent with previous reports.
