WebWhat causes high SVR? Systemic Vascular Resistance (SVR): The measurement of resistance or impediment of the systemic vascular bed to blood flow. An increased SVR can be caused by vasoconstrictors, hypovolemia, or late septic shock. A decreased SVR can be caused by early septic shock, vasodilators, morphine, nitrates, or hypercarbia. WebSep 8, 2024 · Low CO and high SVR characterized the initial circulatory failure after OHCA. During the first 48 h, this pattern reversed to a high CO and low SVR. The majority of patients experienced circulatory stabilization within 72 h after cardiac arrest. We identified four clusters of patients with different severities of circulatory failure.
