Catheter Case Study

Immediately following the placement of the catheter, begin selecting the NAVA level, or the sensitivity of the catheter that is needed to pick up the electrical activity. Neuromuscular signal strength will greatly alter the level needed to support the patient. For example, stronger neuromuscular signals will need a decreased NAVA level to provide ventilation, while weak neuromuscular signals will require a higher NAVA level. A calculation can be done to estimate the level of PEEP needed. The calculation is NAVA Level= PIP-PEEP / (edi peak – edi min). (Servo-I) The Edi peak is the peak of electrical activity of the diaphragm, while the Edi min is the minimum electrical activity. (Kylie – KC Children’s)
