Frequently Asked Questions
Does the solution meet AAMI/ESH/ISO 81060-2 standards?
Yes, our MCU's high-precision ADC and oscillometric algorithm are designed to meet AAMI/ESH/ISO 81060-2 accuracy requirements (±3mmHg for blood pressure, ±5% for heart rate).
What is the typical measurement time?
Typical measurement time is 30-60 seconds, depending on the inflation/deflation strategy and algorithm optimization. Our reference design achieves ~40 seconds average measurement time.
Can the MCU detect irregular heartbeat (arrhythmia)?
Yes, our algorithm library includes irregular heartbeat detection based on pulse interval analysis, alerting users to potential arrhythmia during measurement.
What battery life can be achieved?
With ultra-low sleep current (<1.5μA) and optimized power management, 4×AA batteries can support 500+ measurements, or approximately 1-2 years of typical home use.
Is smartphone connectivity supported?
Yes, our high-end MCU models support BLE connectivity for smartphone integration, enabling data tracking, trend analysis, and cloud synchronization.
Can I get technical support for regulatory certification?
Yes, we provide comprehensive technical support including test reports, design documentation, and consultation to assist with FDA/CE/CFDA certification.
