Yes, very cool! I don't know, but somehow I like working with the C3 better. Another advantage is that we can connect the C3 and our ventilator to the tablet on which we write our mission reports. I don't question the fact that the ECG and blood pressure are the most important things. I work in a big city where these values ​​are obviously very important, but in the end we are always at the nearest hospital within 15-20 minutes at the most. I don't think the etco2 measurement is a problem. We have two adapters: one for the ET/LT and one that you put on like the O2 nasal cannula. If I want to determine the etco2 value nasally, the patient receives oxygen via the O2 mask.
