Abstract
(Anesth Analg. 2022;134:141–148) Monitoring respiratory function is an essential part of caring for children in ambulatory and hospital settings. Yet, assessing ventilation in children by physical examination is difficult due to fast respiratory rates (RRs) and small tidal volumes (TV). In addition, pulse oximeters, capnometers, and other noninvasive respiratory monitors may not reliably assess minute ventilation (MV). While pulse oximeters detect oxygen desaturation, they do not directly monitor ventilation. Capnometers have also been found unreliable in intubated children. Recently a respiratory volume monitor (RVM) (ExSpiron, Watertown, MA) has been developed to measure TV, RRs, and MV noninvasively. It has been found to be accurate in adults and children above 1 year of age. The aim of this study is to evaluate the accuracy of the RVM on RRs, TV, and MV in neonates and infants below 1 year.
