Tranquilizers and sedatives should be avoided in prolonged asthma attacks. Bronchodilators, fluids, aminophylline, and steroids may be used. In acute situations, IV glucocorticoids are frequently used. Results of therapy should be monitored in an objective manner, with peak expiratory flow rates or FEV1. In acute asthmatic attacks, hypocarbia is usual on blood gas analysis. Normal or elevated PaCO2 is a bad sign and requires intensive monitoring and aggressive treatment.
