Probable Cause
TeleMon displays ECG waveforms, a pleth wave, a delayed/
annotated ECG wave, heart rate, %SpO2, and NBP, and transmits
to the IC ECG, %SpO2 and NBP. ECG, %SpO2 and NBP are
calculated by TeleMon, the remainder parameters are calculated
by the transmitter.
It is important to keep the patient within the antenna covering
area because TeleMon does not indicate when and if the
transmitter is outside the covering area.
Probable Cause
No error
Weak or no oscillometric signal
Artifact/erratic oscillometric
signal
Exceeded retry count
Exceeded measurement time
limit
Blocked valves of pneumatics
User aborted measurement
Inflation time-out, or air leak
Safety time-out
Cuff overpressure
Power supply out of range, or
other hardware problem
Safety override fitted or
autozero out of range
Transducer out of range
A/D out of range
EEPROM calibration data CRC
failure
Any communication failures
Cuff has pressure > 15 mmHg
after 3 minutes of measurement
