c. To determine an appropriate
Speed Factor
value, verify that the tube tip echo (highlighted by the
light blue circle in the Figure G-11) is roughly centered inside the middle red frame (see
Section D
–
for a more detailed explanation of this echo). The waveform will update in
real time as the speed factor is changed.

•
If the tube tip echo is to the right of the window (see Figure G-12), decrease the
Speed
Factor
value. This will be the case in the presence of a gas heavier than air (such as
anesthesia), which causes the system waveforms to stretch in time.
