From: Recruitment pattern of the diaphragm and extradiaphragmatic inspiratory muscles in response to different levels of pressure support

Fig. 1

Extradiaphragmatic inspiratory muscle activity increases when lower support levels are applied (P < 0.05). The peak electromyography (EMGpeak) values are normalized to activity at 3 cmH2O pressure support (PS). Values are represented as median (interquartile range). The number of subjects in which EMG parameters could be determined differed per muscle and PS level. Globally, for the alae nasi N = 14, genioglossus N = 10, scalene N = 16, sternocleidomastoid and diaphragm N = 17, and parasternal intercostals N = 15. *Significant difference with PS 3, $significant difference with PS 6 (P < 0.05)
