Contec CMS50D Fingertip Pulse Oximeter
The Contec CMS50D is a lightweight, fingertip pulse oximeter delivering SpO2 and pulse rate (PR) in <10 seconds with ±2% accuracy using Photoelectric Oxyhemoglobin Inspection. Ideal for home, sports, and travel, it features dual-color OLED display, bar graph waveform, low-voltage alarm, auto-standby, and lanyard/case for effortless oxygen saturation tracking during exercise or respiratory monitoring.
Description
Vital Parameters: SpO2 and Pulse Rate Measurement The Contec CMS50D accurately measures blood oxygen saturation (SpO2) and pulse rate (PR) to assess respiratory efficiency and cardiovascular response, aiding in early detection of hypoxemia or tachycardia during high-altitude activities, post-exercise recovery, or chronic conditions like COPD/asthma. This non-invasive tool empowers users with real-time insights into oxygenation levels, supporting proactive wellness adjustments or medical consultations.
Parameters Measured: Quantifies SpO2 (70–100%, ±2% accuracy) and PR (30–250 bpm, ±2 bpm or ±2% deviation) via dual-wavelength LED (red 660 nm, infrared 940 nm) absorption, displaying values, plethysmograph bar graph, and pulse waveform for visual perfusion trends. Includes low-perfusion detection (<0.2%) and alarms for SpO2 <90% or PR deviations, ensuring reliable readings in low-flow states like shock or vasoconstriction.
Sample Requirements: Requires simple finger insertion (adult index/middle, pediatric via adapter) for capillary blood flow detection—no reagents or prep needed. Fits fingers 8–25 mm wide, with soft silicone sensor for comfort; supports all skin tones via adaptive algorithms, ideal for continuous spot-checks in diverse users from athletes to elderly patients.
Throughput: Provides up to 60 spot-checks per hour in manual mode, suited for intermittent monitoring in home care or fitness routines handling 20–100 readings daily. Instant 5–10 second acquisition with one-button operation minimizes user effort, enabling frequent checks during sleep studies or altitude acclimation without fatigue.
Technology: Adopts Photoelectric Oxyhemoglobin Inspection with Lambert-Beer Law-based pulse scanning, using capacity-modulated LEDs and photodetector for ratio-of-ratios calculation of oxygenated vs. deoxygenated hemoglobin. Advanced filtering rejects motion artifacts (up to 2G) and ambient light, with digital signal processing for clean waveforms; CE-certified for safety (Type BF applied part) and low power efficiency.
User Interface and Storage: Dual-color OLED screen (0.96-inch) shows large digits, trends, and battery status, with rotatable display for easy viewing; supports English/Chinese menus for quick setup. No internal storage—manual logging via notebook or app pairing; includes lanyard for neck/wrist wear and carrying case for portability, with audible/visual alarms for low battery or poor signal.
Reagent System: Reagent-free operation with no consumables beyond optional disposable covers for hygiene. Powered by 2 AAA batteries (20–30 hours life), with auto-shutdown after 5 seconds of no finger detection to conserve energy; low-voltage indicator prompts replacement, ensuring uninterrupted use in remote or travel scenarios.
Dimensions and Portability: Ultra-compact at 58 × 32 × 35 mm (W × D × H) weighs 28 g (with batteries), slipping into pockets for on-the-go monitoring. Operates on DC 3V with IP22 splash resistance, functioning in 0–50°C ambient and 15–93% humidity, perfect for aviation, hiking, or daily wellness tracking.
