The finger cuff method provides a reasonable estimate of CO and blood pressure, which does not meet the criteria for clinical interchangeability with the currently used invasive devices. Finger cuff is an easy-to-use hemodynamic monitoring technique. Different devices are currently available, which provide continuous arterial blood pressure (Finapress), whereas only ClearSight (previously known as Nexfin; BMEYE) provides an estimate of CO. In most studies, the criteria for clinical interchangeability (for CO) were not met, when compared with the currently used invasive monitoring systems such as uncalibrated CO via a radial artery line, and calibrated CO either via a pulmonary artery catheter or a femoral artery catheter connected to the PiCCO (Pulsion Medical Systems) or VolumeView (Edwards Lifesciences) devices.
