Excerpt
Sir: We read with interest the article “Isoflurane therapy for severe refractory status asthmaticus in children” wherein the authors describe the use of inhaled isoflurane in a series of children with life-threatening asthma [
1]. However, it was surprising to note that in the algorithm the authors used the peak inspiratory pressure rather than plateau pressure for titration of tidal volumes and as a surrogate for lung hyperinflation. Peak inspiratory pressure does not reflect peak alveolar pressure or the degree of overdistension of alveolar structures, as the high pressures are encountered largely by robust proximal airways. …
