Product Description
Welch Allyn Spot Vital Signs Lxi SpO2 boards GR100035-C and
GR100001, essential components for hospital monitoring devices
The Welch Allyn Spot Vital Signs Lxi SpO2 board is available in two
models: the GR100035-C and the GR100001. Both are original design
PCBs, but their functions differ. The GR100035-C is the basic
version, while the GR100001 can measure data in low perfusion
scenarios. They are compatible with different devices and cannot be
used interchangeably, which will affect some of the SpO2 board's
functionality.
The SpO2 board's main function is to receive and analyze the
optical signals from the blood oxygen sensor and calculate SpO₂ and
pulse rate parameters. Its outer layer has a special coating that
resists electromagnetic interference.
Key Features
- Optical Signal Analysis
After the SpO2 sensor detects data, it transmits red and infrared
light signals to the SpO2 board. The SpO2 board converts and
amplifies the signals before processing them into digital form. - Blood Oxygen Parameter Calculation
The pulse oximetry algorithm separates the optical absorption
differences between arterial blood and resting tissue to calculate
blood oxygen saturation and pulse rate. The GR100001 integrates a
low perfusion compensation algorithm, minimizing measurement errors
even when the perfusion index is extremely low. - Data Transmission and Linkage
Processed parameters and waveforms can be transmitted to the
device's main controller for simultaneous display on the screen.
They can also be time-stamped with parameters such as NIBP and
temperature, creating a complete vital signs report. - Abnormality Monitoring and Alarms
Real-time monitoring of signal quality (e.g., sensor detachment,
insufficient light intensity) is provided. When SpO₂ or pulse rate
falls below preset values, hardware-level signals trigger audible
and visual alarms on the main controller, simultaneously outputting
an error code.
Frequently Asked Questions
Q1: Can the two models be used interchangeably?
A1: Interchangeability is not recommended. Although the SPO2 board
interfaces on the two models are compatible, their functions
differ, which may disable some features, such as low perfusion
measurement. We recommend matching the SPO2 board to the device
model.
Q2: Frequent fluctuations in blood oxygen levels during measurement
indicate a malfunction in the SPO2 board.
A2: Fluctuations in blood oxygen levels are a sign of an SPO2 board
malfunction. We recommend troubleshooting to determine if the SPO2
board is faulty. If confirmed, it is recommended that you replace
the board promptly to avoid inaccurate measurements.
Q3: What is the lifespan of the SPO2 board?
A3: Under normal usage conditions, assuming 50 measurements per
day, the theoretical lifespan is 3 years or 100,000 measurement
cycles. However, actual usage time or number of measurements may
vary depending on actual usage conditions. If the SPO2 board
capacitor bulges or the chip overheats, even if it has not reached
its maximum lifespan, it should be replaced promptly to avoid
measurement errors.
Q4: Is calibration required after replacing the SPO2 board?
A4: Yes. The SPO2 board must be calibrated at three points (80%,
90%, and 100% SpO₂) using specialized tools to ensure compliance
with the standards before continued use. Failure to calibrate the
board may result in measurement errors exceeding ±5%.
