In order to make the monitor safe grounding, the hospital must provide the power socket with complete wire under voltage, zero line and protective grounding in accordance with national standard.
Do not dismantle the housing of the monitor at will for the sake of electric shock. The maintenance and upgrade of the monitor shall be carried out by the qualified and authorized service personnel.

Oximetry measurements can be traced to the early 1930's when German investigators used pectrophotometers to research light transmission through human skin. In 1934, one investigator reported measuring oxygen saturation in blood flowing through closed vessels in animals
In 1964, a San Francisco surgeon developed a self-calibrating, 8- wavelength oximeter that was marketed by Hewlett Packard in the 1970's.
This system was used in clinical environments but was very large, weighing approximately 35 lbs., and had a bulky, clumsy earpiece.
The unit was also very expensive (approximately $10,000.00). However, it did allow for continuous noninvasive monitoring of arterial oxygenation

ECG Measurement is one of the most basic monitoring parameters as well as the most important evaluation indicators of the performance of a Patient Monitor, the characteristics of ECG measurement will depend on the hardware of circuit design and system software of the signal analysis algorithm, the key characteristics mainly in the Elimination of Operationg Frequency Disturbance, baseline drift, ECG waveform distortion, analysis and calculation of ECG characteristic parameter, |

SpO2 plethysmogram measurement is employed to determine the oxygen saturation of 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 SpO2 oxygen saturation of 97%. The SpO2 numeric on the monitor will read 97%. The SpO2 numeric shows the percentage of hemoglobin molecules which have combined with oxygen molecules to form oxyhemoglobin. The SpO2/PLETH parameter can also provide a pulse rate signal and a plethysmogram wave. |
