Study summary

Comparison of intubation time from the time to fix the Trachealtube to the first end-tidal CO2 ventilation by means of the curve on the ventilator at KV standard blade and KV channeled blade

Read the detailed description

In the proposed clinical trial the time measured until the first manual ventilation at 44 study participants with elective anesthesia by using the KV standard blade and KV channeled blade. Bedside the time for tracheal intubation, we documented the view on the monitor which is connected to the instrument, the C\& L classification and POGO Scale.
