a Illustration of monitoring cardiovascular information from a human subject with the reference device and 3MIS system. b Continuous measurement of blood pressure and heart rate. The subject performs a Valsalva maneuvre for 30 s, a breath hold for 90 s and immersion of the opposite hand into ice water for 70 s. c Magnified view of cardiovascular information during the Valsalva maneuver from (b). d Bland–Altman plot comparing HR from the 3MIS system and reference device. e Bland–Altman plot comparing MAP from the 3MIS system and reference device.
