Title:Zoom appears to cause malfunction of the TEG®5000 Thromboelestographic Hemostasis Analyser System when co-installed

Author:Tara BM Feeley and Andrew B Meisner

Abstract:The use of a single device to display thromboelastogram results and a Zoom telecommunications channel may result in an error in the processing of the blood sample. We used a single personal computer to display blood samples processed by the TEG® 5000 Thromboelastograph Hemostasis Analyser System, while using the same personal computer to host a Zoom meeting. A flat line was produced by the sample; however this did not correlate with the clinical scenario or with simultaneous laboratory coagulation results. We hypothesize that there is an incompatibility in running Zoom and the TEG® 5000 Thromboelastograph Hemostasis Analyser System together, and this may be due to the use by both applications of Microsoft’s dynamic-link library.
