Ventilators have helped patients breathe more or less in this way for centuries—filling the lung by force with an amount of air determined by the caregiver.… Read the rest

Diaphragm Electrical Activity: Post 3

Post 3: Physiological interpretation of the diaphragm electrical activity (EAdi) waveform.

Breathing is an extremely complex process and we are still learning. The EAdi waveform adds a new dimension to interpreting breathing at the bedside. It provides information about central respiratory drive, timing of breathing, and synchrony between ventilator assist and patient effort.… Read the rest
