From: Respiratory modulation of oscillometric cuff pressure pulses and Korotkoff sounds during clinical blood pressure measurement in healthy adults

Parameter Mean bias (Hz) Limit of agreement (Hz)
Normal breathing
 fO 0.006 [−0.124,0.136]
 fK 0.044 [−0.119,0.207]
Deep breathing
 fO −0.005 [−0.109,0.098]
 fK −0.010 [−0.123,0.104]
