Introduction: Advanced hemodynamic monitoring is need of today especially in patients with limited cardiac reserve. With the advent of
smartphones & specially designed applications, hemodynamic monitoring becomes quite easy.
Materials & Methods: Patient was pre – medicated with Inj. Fentanyl & inj. Glycopyrrolate, induced with Inj. Etomidate & Inj. Vecuronium and
maintained with mixture ofIsourane, Nitrous Oxide & Oxygen. An arterial line was secured in Left Radial Artery. We used the CAPSTESIA app
to take picture of the arterial waveform using a smartphone. Demographic data of the patient was fed in the app. App used it's pre- fed algorithm to
give the real time Cardiac Output, Pulse Pressure variations, Cardiac Index based upon the arterial waveform.
Results: Using the application we were able to monitor the cardiac output of the patient in real time using semi- invasive means. It enabled us to
regulate the uid management of the patient and avoid any adverse cardiac events (hypotension). With Pulse Pressure variation also available in
real time, we were able to restrict use of vasopressors since the Left Ventricle Ejection Fraction of the patient was 35 % on ECHO. Surgery was
conducted without any untoward event. Patient was successfully extubated and sent to PACU.
Conclusions:Advanced hemodynamic monitoring is time consuming using manual methods. We found the smartphone app CAPSTESIA pretty
useful for semi-invasive hemodynamic monitoring of the Cardiac Output, Pulse Pressure variation, Cardiac Index,etc in real time.
