Table 1 Nomenclature of variables used
From: Evolution of inspiratory muscle function in children during mechanical ventilation
Paw | Pressure signal recorded at endotracheal tube |
ΔPaw | Difference between the lowest Paw during an occluded breath and preceding end-expiratory Paw |
ΔPawmax | Largest ΔPaw deflection amongst 5 breaths of an occlusion maneuver |
Maximum ΔPawmax | Largest ΔPawmax deflection over 3 occlusion maneuvers of a single recording in time |
ΔPawtwitch | Pressure decrease at occluded endotracheal tube generated by magnetic stimulation of the phrenic nerves |
EAdi | Electrical signal recorded by electrodes in esophagus |
EAdimax | Peak value of EAdi during an occluded breath |
NME | Ratio of ΔPaw to EAdimax for an occluded breath |
NMEoccl | Median NME value amongst 5 breaths of an occlusion maneuver |
Median NMEoccl | Median NMEoccl value over 3 occlusion maneuvers of a single recording in time |
