Moreover, during weaning, we can look at the respiratory rate / tidal volume<br />
ratio (Rate Volume Ratio = RVR). As with fatigue, newborns decrease tidal<br />
volume and increase respiratory rate and there<strong>for</strong>e increase the RVR. This<br />
ratio is a weaning criteria with high sensitivity and high specificity to predict<br />
successful extubation in adults (area under the ROC curve is 0.89). [41] As yet,<br />
there are no data <strong>for</strong> neonates available, but the rate volume ratio (RVR) can<br />
be used very well also <strong>for</strong> monitoring the weaning process in neonates. Based<br />
on the neonatal physiology, a gradual increase in RVR can indicate a<br />
beginning fatigue of the patient. In this case an increase of pressure support<br />
level (Pinsp) might be necessary.<br />
