The CMS70A is a CE‑approved table‑top pulse oximeter for monitoring SpO2 and pulse rate in adult, pediatric and neonatal patients. It features a TFT display with waveform/graph, perfusion index (PI), alarm functions, data storage and real‑time transmission to a PC, and is designed for clinical, hospital and home use.
The device is designed and configured for adult, pediatric and neonatal use. Use appropriate-sized probes and sensor placement for neonates and pediatrics as described in the user manual.
SpO2 range is 0%–100%. Accuracy is ±2% for values in the 70%–100% range. Accuracy below 70% is not specified in the product specification and may be less reliable.
Pulse rate range is 30–250 beats per minute. Accuracy is ±2 bpm or ±2%, whichever is greater.
The unit contains a rechargeable Li‑Polymer battery and provides at least 1 hour of continuous operation after a full charge. It charges from AC 100–240V, 50/60Hz input. For exact charging time and charging procedure refer to the user manual.
Yes — the CMS70A supports real‑time data transmission to a computer via the included data cable. A PC software disk is provided in the standard package. See the software user guide for OS compatibility and data export procedures.
Standard package includes user manual, power cord, data cable, oximeter probe and PC software disk. Additional/optional oximeter probes are available (refer to the product configuration BOM or contact your supplier for probe model options).
Yes. The CMS70A has adjustable upper and lower alarm limits for SpO2 and pulse rate, with audible alerts for alarms and low voltage. Pulse rate audio indication (beep) can be toggled on or off.
It uses a TFT screen (320 × 240 resolution) with numeric SpO2 and PR values, a bar graph and a waveform. Screen brightness and display modes are adjustable to suit different viewing conditions.
Weak‑filling performance is specified down to a pulse‑filling ratio of 0.4%, enabling readings in low perfusion states. Light resistance is strong, with minimal deviation (specified < ±1%) under varying light conditions.
Common causes of unstable readings include motion, poor probe placement, cold or vasoconstricted extremities, nail polish/artificial nails, ambient light interference or a loose probe. Reposition the probe, warm the patient’s extremity, remove nail polish if applicable, minimize motion and ensure the probe is fully seated. If problems persist, consult the user manual or contact technical support.
Follow the cleaning and disinfection procedures in the user manual. Generally, wipe the main unit with a soft cloth dampened with a mild disinfectant; do not immerse the unit in liquid. Clean reusable probes per the manufacturer's instructions and avoid harsh chemicals or high‑temperature sterilization unless specified.
Routine user calibration is not required. Regular maintenance may include inspection of probes and cables, battery performance checks and cleaning. For service intervals, calibration, or repairs, follow the manual and contact authorized service personnel or your supplier.
Yes — it supports continuous monitoring and includes alarm functions for ongoing observation. Note battery life: on internal battery it operates for at least one hour; for extended continuous monitoring use AC power or ensure the unit is connected to mains power.
Pulse oximeters provide useful trend and monitoring information but are not a substitute for clinical assessment. Readings may be affected by motion, poor perfusion, dyes, nail polish, ambient light and abnormal hemoglobins. Always use the device in accordance with the user manual, observe alarms promptly and consult clinical staff for medical decisions.
