11 Essentials for Accurate Pulse Oximeter Readings

11. Choosing, maintaining, and validating your device

Buy a pulse oximeter from reputable brands with positive independent reviews and regulatory clearances when possible. Look for FDA clearance or similar certifications to ensure basic performance standards. Read the manual for recommended cleaning steps and avoid harsh solvents that can damage sensors. Replace batteries as directed and store the device in a dry place away from extreme temperatures. Periodically validate your home device against clinic-grade equipment if you have the chance; many clinics will compare readings during a visit. Keep a backup unit if monitoring a high-risk person to avoid gaps if a device fails. Finally, check sensor integrity regularly: loose clips, worn LEDs, or cracked casing can degrade accuracy. Proper care and occasional cross-checks will keep your device useful for reliable home monitoring.
