A clinical scoring system has been developed to detect impending or existing respiratory failure in childhood status asthmaticus. The score is based on a numerical evaluation of oxygenation, gas exchange, work of breathing, airway obstruction, and cerebral function. A highly significant correlation exists between the score and arterial carbon dioxide tension (Pco2). The score and arterial oxygen tension (Po2) during air breathing also appear to be significantly related.
