Summary

Volumetric capnography is an interesting and non-invasive tool for monitoring ventilation in mechanically ventilated patients. The aim of this study was to test the effect of positive pressure ventilation and different body positions on volumetric capnograms.

Detailed description

In this interventional study awake and healthy volunteers will be submitted to spontaneous, pressure support and control pressure ventilation using a tight nasal mask. Volumetric capnography and electrical impedance tomography (EIT) will be continuously recorded during the protocol. Different body positions were randomly tested. Analysis of global and regional distribution of ventilation using EIT will be matched with changes observed in volumetric capnography-derived parameters.
