Research Article: Noninvasive Point of Care Device for Assessing Cardiac Response to Acute Volume Changes
Introduction:
It is important in many clinical settings to assess changes in thoracic volume status, including detecting the development of subclinical congestion in chronic heart failure patients. However, physical exam findings may be insensitive to these changes. – It has been established since the s and s that assessing the changes in arterial pressure pulse amplitude during a Valsalva maneuver helps with assessing central volume/filling pressure status. – Normally during a Valsalva maneuver, the increased thoracic pressure…
