Measurement of Pulse Pressure Variation and Cardiac Output by a New Application for Android™ (Captesia™)

This study test the agreement and accuracy of Pulse Pressure Variation (PPV) and Cardiac Output (CO) obtained by the Android application Capstesia™ against the gold standard : PPV and CO calculated by thermodilution.

About this study

Pulse pressure variation (PPV) remains a good predictor of fluid responsiveness in the OR. However, PPV can be time-consuming to calculate (manual determination), is not always displayed on monitoring screens nor reliable through visual assessment and needs additional devices to be displayed. A new Android application (Captesia) automatically calculates the PPV utilizing a digital photograph of the arterial waveform from the monitor. The application determines the PPV by selecting peaks and troughs of the arterial curve.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • patients scheduled for coronary artery bypass

Exclusion criteria

  • patients with arrhythmias like atrial fibrillation
  • patients with valvular insufficiency

Treatment and study plan

Calculation of PPV and CO with two methods

Other

Primary outcomes

  1. PPV

    Time frame: at time of surgery

    the Pulse Pressure Variation will be calculated by the Android Application (Captesia) and by the Picco before and after a meneuver of volume expansion, which goal is to change the cardiac output.

Secondary outcomes

  1. CO

    Time frame: at time of surgery

    the Cardiac Output will be calculated by the Android Application (Captesia) and by thermodilution before and after of volume expansion, which goal is to change the cardiac output.
