title: [Severe acute asthma in the emergency room: amelioration of decreased peak flow rate is interpreted with difficulty].
abstract: We report a severe acute asthma case whose course was marked by persistent hypoxemia whereas proximal flows were normalized. This discordance reveals a ventilation/perfusion mismatch. This data suggests that care must be taken in interpreting the peak flow improvement during acute severe asthma management.
