Ventilatory changes during the use of heat and moisture exchangers in patients submitted to mechanical ventilation with support pressure and adjustments in ventilation parameters to compensate for these possible changes: a self-controlled intervention study in humans
Abstract:ObjectiveTo evaluate the possible changes in tidal volume, minute volume and
respiratory rate caused by the use of a heat and moisture exchanger in
patients receiving pressure support mechanical ventilation and to quantify
the variation in pressure support required to compensate for the effect
caused by the heat and moisture exchanger.MethodsPatients under invasive mechanical ventilation in pressure support mode were
evaluated using heated humidifiers and heat and moisture exchangers. If the
volume found using… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
