Clinical validation  

Blood oxygen saturation was measured by pulse filtering using intelligent pulse  

To provide accurate blood oxygen measurements, even during exercise  

Still accurate under low perfusion or other harsh conditions  

Yonker automatically adjusts to each patient's condition  

To provide fast and reliable reads
