Diaphragmatic electrical activity: a new tool to assess lung hyperinflation?
447 September 2014 “ EXPIRATION and slow decrease of light together reaching minimum together ... in about 10 s and immediately cry as before. Silence and hold for about 5 s.” In the script for his late play “Breath,” Samuel Beckett conveys in sound and light his awareness of long and vital expiratory times. His personal experience with emphysema might have provided some of the inspiration. In ...
متن کاملInterest of Monitoring Diaphragmatic Electrical Activity in the Pediatric Intensive Care Unit
The monitoring of electrical activity of the diaphragm (EAdi) is a new minimally invasive bedside technology that was developed for the neurally adjusted ventilatory assist (NAVA) mode of ventilation. In addition to its role in NAVA ventilation, this technology provides the clinician with previously unavailable and essential information on diaphragm activity. In this paper, we review the clinic...
متن کاملElectrical and mechanical activity in the human lower esophageal sphincter during diaphragmatic contraction.
To determine the effect of contraction of the diaphragm on the lower esophageal sphincter (LES) pressure, we studied eight healthy volunteers during spontaneous breathing, maximal inspiration, and graded inspiratory efforts against a closed airway (Muller's maneuver). Electrical activity of the crural diaphragm (DEMG) was recorded from bipolar esophageal electrodes, transdiaphragmatic pressure ...
متن کاملSpontaneous activity in peripheral diaphragmatic lymphatic loops.
The spontaneous contractility of FITC-dextran-filled lymphatics at the periphery of the pleural diaphragm was documented for the first time "in vivo" in anesthetized Wistar rats. We found that lymphatic segments could be divided into four phenotypes: 1) active, displaying rhythmic spontaneous contractions (51.8% of 197 analyzed sites); 2) stretch-activated, whose contraction was triggered by pa...
متن کاملFractionated electrical activity and continuous electrical activity: fact or artifact?
ENDOCAVITARY MAPPING during chronic ventricular tachycardia in patients with healed myocardial infarction and/or ventricular aneurysms has been used to locate the region from which ventricular tachycardia originates. During the process of mapping, bipolar electrograms with unusual configurations have been recorded from the chronically ischemic or healed infarcted regions, both with electrode ca...
