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 major surgery which requires a CO and PPV monitoring as standard of care

Exclusion criteria

patients with arrhythmias like atrial fibrillation
patients with valvular insufficiency

Treatment and study plan

Capstesia

Device

Picture of the arterial waveform taken with a smartphone

Primary outcomes

Agreement and precision of PPV and CO during 5 surgical phases (postinduction, pre incision, postincision, end of surgery and at least one episode of hypotension)

Time frame: during surgery

We will compare PPV and CO given with the EV-1000 and the capstesia app at different phases of the surgery
