Ventilator auto-triggering by cardiac electrical activity during noninvasive ventilation with neurally adjusted
1Department of Intensive Care Medicine Osaka Women's and Children's Hospital Izumi Japan.
Abstract:
Neurally adjusted ventilatory assist (NAVA), by capturing the electrical activity of the diaphragm, improves patient-ventilator synchrony. It is, however, not completely immune from auto-triggering by cardiac electrical activity as illustrated in this case. Stringent observation of respiratory rate and vigilance for this phenomenon is warranted when using NAVA.

Factors Affecting Pulmonary Ventilation
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
