The Microstim
DB3 is the latest addition to the Microstm range, which
has been popular with anaesthetists worldwide since 1985
and has served extremely well, being low cost, easy to
operate and reliable in use.
This Nerve Stimulator has four
settings:
Train of Four
Double Burst
Stimulation
Post Tetanic Count
Continuous 1 Hz
We are often asked 'Why does the Microstim not have a
display to show the delivered current?' This is why:
1. The current required for supramaximal stimulation
varies considerably between patients. The best way to
establish supramaximal stimulation is to gradually
increase the stimulus current until the response is
elicited.
2. Because the Microstim is a constant current
stimulator, it is not subject to current-reduction as a
result of high skin impedance. A non-constant current
stimulator needs a display to indicate the delivered
current.
3. A numerical display can give the erroneous
impression to the inexperienced user that the display
somehow indicates the magnitude of the muscle
response.
