How to ensure the measurement stability of a patient monitor?

Measurement stability is a crucial indicator to evaluate the quality of a patient monitor.

In the measurement of blood oxygen saturation, the monitor utilizes the dual-wavelength pulsatile photoplethysmography technique. By analyzing the differential absorption of red and infrared light by oxygenated hemoglobin (HbO2) and hemoglobin (Hb) in the blood, real-time blood oxygen saturation levels are calculated. To ensure stable measurement results, the monitor employs high requirements for LED emission and photodetector reception to counter interference. The HM-10 oximetry probe utilizes a ten-pin physical connection design, enabling separate shielding for signal transmission and maximum stability through a two-pin external shielding mechanism.

For electrocardiogram (ECG) signal acquisition, the patient monitor employs a five-lead ECG system. It captures bioelectric signals and converts them into digital outputs. The HM10 monitor features five ECG acquisition channels and one driven lead, offering an accurate and stable display of ECG waveforms along with respiratory and heart rate information. To enhance signal transmission stability, the ECG module utilizes a twelve-pin physical connection method and implements signal pin separation for shielding, further improving the reliability of signal transmission.

These highlighted technological advancements play a pivotal role in ensuring measurement stability in patient monitors. By leveraging high-quality photoplethysmography and physical connection techniques, the monitor effectively mitigates signal interference and obtains stable and accurate measurement results. These technologies enable the monitor to perform reliably in diverse environments, providing healthcare professionals with reliable data support for better patient assessment and medical decision-making.

When selecting a patient monitor, measurement stability should be a significant consideration. Manufacturers employ key technologies such as dual-wavelength photoplethysmography and physical connection methods to ensure stability in blood oxygen saturation and ECG signal measurements. These advancements guarantee reliable performance and accuracy. Choose a monitor that prioritizes measurement stability to deliver optimal healthcare outcomes.
