The software serves as a bridge between specialized hardware—such as devices from Contec, Pulox, and Cooper Medical Supplies—and your desktop computer. It enables users to transfer and interpret data regarding blood oxygen saturation ( SpO2cap S p cap O sub 2 ), heart pulse rate, and perfusion index ( PIcap P cap I Core Technical Specifications Current Stable Version SpO2 Assistant v3.1 (including 3.1.0.4 and 3.1.0.6 builds) License Type Freeware (100% Free to Use) Operating System Windows XP, Vista, 7, 8, 10, and 11 (32-bit & 64-bit emulation) Primary Executable SpO2.exe Hardware Connectivity USB Data Cable or Bluetooth Wireless Sync Compatible Hardware Contec (CMS50F, CMS50D+), Pulox (PO-250, PO-300, PO-500), and others Key Features of SpO2 Assistant 3.1 1. Real-Time Data Streaming & Waveform Capture When connected to a continuous-use pulse oximeter, the software provides a live dashboard. It reflects a plethysmogram waveform , a real-time pulse bar chart, and updating numeric values for both oxygen levels and heart rate. This feature allows for visual validation of data quality, making it easier to spot when an incorrect reading occurs due to sudden finger movement or poor sensor placement. 2. Historical Data Storage and Synchronization The application is widely used for downloading raw storage logs from overnight oximetry recordings. Users can wear a wrist or finger-pulse oximeter while sleeping to check for sleep-disordered breathing issues, like sleep apnea. The data can then be extracted into .SpO2 log files on a computer for long-term tracking. 3. Comprehensive Report Generation The software converts raw data tables into easy-to-read graphical trend charts. These files can be exported as printable documentation to share with a physician during healthcare check-ins. 4. Customizable Parameter Alarms Users can establish specific high and low safety thresholds for both SpO2cap S p cap O sub 2 percentages and pulse rates within the interface. If a user's metric drops outside of these parameters, the PC sounds a clear auditory alarm prompt.

SpO2 Assistant 3.1 is a free, Windows-based health monitoring application designed to track, review, and analyze blood oxygen saturation ( SpO2cap S p cap O sub 2 ), pulse rate (PR), and Perfusion Index (PI) in real time. Primarily bundled with compatible medical hardware like Contec or Pulox finger pulse oximeters, this software utility acts as a critical link between a patient's physical oximeter device and a computer. It allows users to export data, view live plethysmogram waveforms, and even format data for sleep apnea tracking suites like OSCAR . Core Technical Specifications The software functions as an interface for medical data logging. 1 architecture: Operating System Compatibility: Fully optimized for Windows 10 and Windows 11 (32-bit and 64-bit systems). Executable File Name: SpO2.exe. Primary Developer Origin: Contec Medical Systems / Cooper Medical Supplies. License Type: Freeware (No activation keys or subscriptions required). Hardware Connectivity: Supports Universal Serial Bus (USB) data cords or wireless Bluetooth sync, depending on the pulse oximeter model. Critical Features of SpO2 Assistant 3.1 The 3.1 version introduced vital stability patches over its predecessors (such as versions 2.4 and 2.7), particularly regarding driver detection on modern Windows platforms. +-------------------------------------------------------------+ | SpO2 Assistant 3.1 | +-------------------------------------------------------------+ | | v v [Real-Time Monitoring] [Review & Analysis] - Live Waveform Graphs - Historical Trends - Audio Alarm Alerts - Data Export (.csv/.dat) - Auto-Device Scan - OSCAR Sleep Sync 1. Real-Time Telemetry and Waveform Plotting When a device is connected, the software automatically scans for active COM ports to sync incoming data. It renders a real-time plethysmogram (the visual waveform of your pulse) alongside real-time parameter values, allowing users to watch signal stability on a large monitor rather than a tiny oximeter screen. 2. Parameter Alarm Safeguards Users can configure software-based thresholds for high or low SpO2cap S p cap O sub 2 and pulse rate boundaries. If a user’s oxygen drops below a configured threshold (for example, below 92%), an audio alert prompts from the computer, which is highly useful for continuous night-time monitoring. 3. Data Export and Sleep Apnea Tracking Integration One of the main reasons patients look for the free 3.1 version is its ability to save session data into .dat or .csv files. These logged files can be imported directly into the OSCAR Oximetry Wizard, enabling continuous continuous positive airway pressure (CPAP) users to overlay their blood oxygen levels directly onto their sleep therapy data. Step-by-Step Installation and Device Setup Follow these steps to safely initialize your oximeter with a Windows PC using the software: Download the Installer: Obtain the SpO2 Assistant 3.1 setup package through validated channels such as the Pulox Software Portal or vetted software repositories like Software Informer . Install Drivers First: Before plugging in your hardware, run the installer file to ensure the necessary virtual COM port drivers are registered on your operating system. Establish Connection: Use the included USB cable to join the oximeter to your PC, or turn on the oximeter's Bluetooth discovery mode. Launch the App: Open SpO2.exe . Click the Auto-Scan utility button to let the application automatically query and find your device. Initiate Recording: For continuous data logging (such as an overnight sleep trial), ensure the device's internal storage sync is turned "On" or leave the PC running with the live tracking activated.
