NCT03599440

Brief Summary

Hemodynamic monitoring of the critically-ill patients is increasingly performed using an arterial pulse contour-based cardiac output device such as the proAQT system. The aim of this study is to evaluate the effect of extending the pressure lines on the arterial pressure wave and the calculated hemodynamic variables when using the proAQT system.

Outcome Measures

Primary Outcomes (1)

  • relative change in ProAQT-calculated cardiac output after placement of extension lines.

    relative change (in % of the baseline measurement) in cardiac output following increase in length of the extension line.

    one minute of measurement after changing the length of the extension line.

Secondary Outcomes (6)

  • change in Area Under the Curve (AUC) of the arterial pressure wave form after placement of extension lines.

    one minute of measurement after changing the length of the extension line.

  • relative change in ProAQT-calculated SVR after placement of extension lines.

    one minute of measurement after changing the length of the extension line.

  • relative change in ProAQT-calculated diastolic blood pressure after placement of extension lines.

    one minute of measurement after changing the length of the extension line.

  • relative change in ProAQT-calculated systolic blood pressure after placement of extension lines.

    one minute of measurement after changing the length of the extension line.

  • relative change in ProAQT-calculated stroke volume variation after placement of extension lines.

    one minute of measurement after changing the length of the extension line.

  • +1 more secondary outcomes
