mohamad Posted January 22, 2015 Share Posted January 22, 2015 We have a new Babylog 8000 plus ventilator in our NICU for the first time and I have 2 questions about it: 1- What is the commonly used values regarding volume triggering ? 2- what is the acceptable percentage of leak ? ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ Mohamad Ismail, Neonatology resident, Mansoura, Egypt . 1 Link to comment Share on other sites More sharing options...
Sirin Posted January 26, 2015 Share Posted January 26, 2015 1.Volume guaranteed (VG) provides automatic adjustment of the peak inspiratory pressure for ensuring a minimum set tidal volume. The flow sensor of the ventilator should calibrated before starting VG ventilation. We set VT of 3.5-4 ml/kg for infants >1000 g and 5 ml/kg <1000 g. During SIMV/SIPPV/PSV + VG, all ventilator settings are the same, only the PIP limit sets 10 cm H2O above the PIP that is used during the conventional SIMV mode. At the follow-up, the set VT is adjusted according to the arterial blood gas analysis. 2. The leak is very important during VG ventilation, no more than 40%; higher leak results in erroneous measurement of delivered VTe (expire) and lead to a discrepancy between set VT and delivered VT.

Manan Posted January 27, 2015 Share Posted January 27, 2015 VG usually between 2 to 4 ml/kg. we use 4 ml/kg. Acceptable leak is around 20% Link to comment Share on other sites More sharing options...
mohamad Posted February 5, 2015 Author Share Posted February 5, 2015 SirinDrMananParikh Thanks for your answers, but what about the degree of sensitivity that is commonly used ? Link to comment Share on other sites More sharing options...
