Table 1 Measurement of Edi under SBT

From: Predicting extubation readiness by monitoring the electrical activity of the diaphragm after prolonged mechanical ventilation: a pediatric case report

Day Edi
(mcV)
TV
(mL)
RR
(breaths/min)
RSBI
(breaths/min/mL/Kg)
NVE
mL/mcV
53 70  
55 40 40 35 5.6 1.0
57 25 40 40 6.4 1.6
58 22 35 42 7.7 1.6
59 13 33 42 8.1 2.5
  1. After reintubation, Edi and NVE were recorded during daily trials of SBT. Immediately after reintubation, Edi was higher than 70 mcV but gradually decreased to 13 mcV on day 59
  2. Edi electrical activity of the diaphragm (mcV), TV tidal volume (mL), RR respiratory rate (/min), RSBI rapid shallow breathing index (RR/{TV/body weight}), NVE neural ventilatory efficiency (mL/mcV)
