  • Page 71: Nibp Processing

    System Processing Description ARGUS VCM NIBP Processing Overview The oscillometric technique does not use Korotkoff sounds to determine blood pressure. The oscillometric technique monitors the changes in cuff pressure caused by the flow of blood through the artery. The monitor inflates the cuff to a pressure that occludes the artery.
  • Page 72 ARGUS VCM System Processing Description On clinical trial perspective, overall system accuracy is not easy to be determined. The clinical trial test protocols have been tried and have been described in many treatises, and international standards. So, there are many methods to determine the overall system accuracy of Automated Sphygmomanometer using the oscillometric method.

  • Page 73: Spo2 Processing

    System Processing Description ARGUS VCM Processing Overview Pulse oximetry works by applying a sensor to a pulsating arteriolar vascular bed. The sensor contains a dual light source and photodetector. Bone, tissue, pigmentation, and venous vessels normally absorb a constant amount of light over time. The arteriolar bed normally pulsates and absorbs variable amounts of light during systole and diastole, as blood volume increases and decreases.

It does not detect significant amounts of dysfunctional hemoglobin, such as carboxyhemoglobin or methemoglobin.
