Why the study?
Cardiac output monitoring is essential in critically ill patients, but the validity of the Capstesia app compared to the echo-based velocity time integral technique needed assessment.
Does the smartphone-based application CapstesiaTM provide valid cardiac output monitoring compared to the traditional echo-based VTI technique in hemodynamically unstable patients with shock?
Does the smartphone-based application CapstesiaTM provide valid cardiac output monitoring compared to the traditional echo-based VTI technique in hemodynamically unstable patients with shock?
The CapstesiaTM smartphone app provides comparable cardiac output measurements to traditional echo-based VTI in hemodynamically unstable patients, offering a reliable alternative for continuous monitoring.
Capstesia may support noninvasive COP monitoring in shock; leaves open need for randomized validation before clinical adoption.
Background: Cardiac output (COP) monitoring is a cornerstone in the management of critically ill patients. Objectives: to assess the validity of CapstesiaTM app for COP monitoring compared to the traditional echo-based velocity time integral (VTI) technique in hemodynamically unstable patients. Patients and Methods: In prospective cohort study, 50 cases were admitted with shock state and candidates for continuous COP monitoring. Readings obtained from 50 patients were measured simultaneously by CapstesiaTM app and VTI method. Results: The mean age of participants was 63±11 years, 29 patients were males, and 33 patients suffered from septic shock. With a p-value of 0.76, the two methods that were compared did not differ from one another in a way that is statistically significant, the level of agreement between the two methods was least in chronic kidney disease (CKD) patients. Conclusion: Smartphone application CapstesiaTM is a reliable alternative to the traditional echo-based VTI technique in continuous COP monitoring in hemodynamically unstable patients.
