Which of the following is NOT a method of inflation on the MD1250?

The method that is NOT used for inflation on the MD1250 is electric. The MD1250 operates using protocols for inflation that typically rely on manual, auto, or oral methods. Manual inflation involves using a pump or balloon to inflate the device, while auto inflation may include mechanisms that automatically inflate the device based on certain settings. Oral inflation allows for inflation by blowing air into the device directly. Electric inflation, on the other hand, is not a protocol utilized by this specific model, which means it's not a valid method for inflating the MD1250. Understanding these various inflation methods is crucial in ensuring the proper usage and operation of the equipment.
