1 Select the setup key
2 Select Mother > ECG Calibration.
3 Select Calibration or OFF (default).
4 Select OK.
The monitor creates a square wave in the ECG area. Compare the square wave with the ECG
gauge. If the error is larger than 0.5mm, change the ECG gain.
When the error is smaller than 0.5mm, calibration is completed. Disable ECG calibration in the
same directory.
NOTE:
The ECG Source selection, ECG Gain selection and ECG calibration are only available
in the F9 Express monitor with standard configuration.
9.2 Maternal SpO
9.2.1 Introduction
The monitor provides continuous monitoring of functional arterial oxygen saturation (SpO
pulse rate (PR) for pregnant women.
SpO Plethysmogram measurement is employed to determine the oxygen saturation of
2
hemoglobin in the arterial blood. If, for example, 97% hemoglobin molecules in the red blood
cells of the arterial blood combine with oxygen, then the blood has a SpO
97%. The SpO numeric on the monitor will read 97% .The SpO
2
of hemoglobin molecules which have combined with oxygen molecules to form oxyhemoglobin.
The SpO /PLETH parameter can also provide a pulse rate signal and a plethysmogram wave.

SpO Plethysmogram Measurement Principle:
2
 Pulse oximetry is a continuous and noninvasive monitoring technique used to estimate the
measurement of arterial oxygen saturation. It measures the amount of light penetrating the
patient tissue and reaching the receiver. The reading, obtained through pulse oximetry, uses a
light sensor containing two sources of light (red and infrared) that are absorbed by
hemoglobin and transmitted through tissues to a photodetector.
 The amount of light penetrated depends on multiple factors and most of them are constant.
However, the arterial blood flow changes with time passing by as is pulsative. The arterial
