[Asthmatic crisis].

Attack of asthma (bronchospasm) is a group of sharp breathing manifestations. It can appear in an asthmatic patient or in a patient who has not asthmatic antecedents. It exists a large variety of clinic forms: breathing, neuro-psychic and cardio-circulatory signs. In front of a bronchospasm, oxygenation has priority. The practitioner can use medicinal therapeutics like corticoids and must supervise ventilation.
