Pediatric postoperative patients are at increased risk for post-operative respiratory
complications such as hypoventilation. There is no objective measure of early respiratory
parameters that would predict respiratory compromise after surgery efficiently in pediatric
patients. Current respiratory assessment in non-intubated patients relies on oximetry data,
impendence respiratory rate monitor and subjective clinical assessment. Pulse oximetry has
been extremely helpful in recognizing oxygen desaturations but it is a late indicator of
respiratory decline. New advances in technology and digital signal processing have led to
the development of an improved impedance based Respiratory Volume Monitor (RVM). The RVM
(ExSpiron™, Respiratory Motion, Inc.; Waltham, MA) has been shown to provide accurate
real-time, continuous, non-invasive measurements of tidal volume (TV), minute ventilation
(MV) and respiratory rate (RR) mostly in adult patients. The investigators' primary
hypothesis is that the non-invasive, impedance-based RVM monitor will accurately reflect TV,
RR and MV in pediatric patients.
