Interest of Monitoring Diaphragmatic Electrical Activity in the Pediatric Intensive Care Unit

Figure 5

Daily evaluation of ventilatory drive in a 5-year-old patient with cervical myelitis. Each day, mean inspiratory EAdi was recorded during 5 minutes with the ventilation prescribed by the attending physician (grey bars) and 5 minutes under continuous positive airway pressure (CPAP, white bars). Inspiratory EAdi was also measured during 2 voluntary maximal inspiratory efforts (triangle). A period of overassistance with absent ventilatory drive was detected at day 3 (*). The recovery of the ventilatory drive was observed rapidly after adjustment of the support. (PSV: pressure-support ventilation; SIMV: synchronized intermittent mechanical ventilation).
