Design outcomes

Primary

Measure	Time frame
We compare EtCO2 measured by capnometry by using an nasal canulae with a carbon dioxide sampling port and partial pressure of carbon dioxide (PaCO2)	—

Secondary

Measure	Time frame
we investigated whether spontaneous deep breathing affected dissociation between PaCO2 and EtCO2.	—
