Non invasive pressure signal verification.
Activate the non invasive pressure signal at the Omicrom FT (for some models, it
is necessary to disactivate previously the invasive pressure signal) and activate
the displaying of the oscillating pressure at the cuff.
Inflation pressure.
a) Using a T connector, connect the Omicrom FT, the pressure manometer
and a cuff, that must be wrapped around a rigid cylinder which is
approximately the same size as an arm.
b) Initiate the pressure measurement at the Omicrom FT.
c) Check that the inflation pressure is approximately 160 mmHg for adults
and 100 mmHg for neonates.
Small air leakage verification.
a) Using a T connector, connect the Omicrom FT, the pressure manometer
and a cuff, that must be wrapped around a rigid cylinder which is
approximately the same size as an arm.
b) Initiate the pressure measurement at the Omicrom FT.
c) Do not stop the measurement procedure.
d) Check that the waveform monitored is flat during all pressure steps.
e) Check that the pressure value at each step is accurate.
f) Finally, check that the pressure is below 10 mmHg and that the Omicrom
FT generates a weak signal alarm, so there are not air leakages.
Overpressure cut-out.
a) Using a T connector, connect the Omicrom FT, the pressure manometer
and a cuff, that must be wrapped around a rigid cylinder which is
approximately the same size as an arm.
b) Initiate the pressure measurement at the Omicrom FT.
c) When the cuff pressure is maximum, you have to produce manually an
overpressure higher than 300 mmHg. Check that the safety system that
protect against overpressure is operating and the pressure is limited.
Pressure measurement.
a) Place the cuff correctly around the upper arm and initiate a normal
measurement.
b) Check that the cuff inflation is correct.
c) When the measurement finishes, check that the cuff is deflated
completely and the pressure values are showed at Omicrom FT display.
d) Check that the pressure values measured can be considered as correct
and that consecutive measurements are repeatable.
Non invasive pressure alarms:
a) With no cuff connected initiate a measurement and check that Omicrom
FT shows an alarm message indicating “Inflation timeout” after 45
seconds (20 for neonates).
b) With the cuff wrapped around a rigid cylinder initiate a measurement and
check that Omicrom FT shows an alarm message indicating “Weak
signal”.
