Background

  • Hydrogen fluoride (HF) is a byproduct of standard fire suppression systems.[1]

Clinical Features

  • Exposure to HF may result in rapidly progressive or fatal respiratory failure despite minimal external evidence of injury. [2]
  • Symptoms include shortness of breath, cough, or hypoxia; there must be a high level of suspicion for HF inhalation.[3]

Differential Diagnosis

Evaluation

Management

  • Treatment is supportive.
    • If hypocalcemia is present, administer nebulized calcium gluconate (1.5 ml of 10% calcium gluconate in 4.5 ml water) q4hr until normalization of serum calcium levels. [4]
    • In the absence of significant burns, consider steroids if symptoms do not improve. [5]

Disposition

Complications

  • Bronchopneumonia can develop within a week.[6]
