Smartphone Application Monitoring of Acceleration Forces During Pneumatic Tube System Transport of Emergency Department Patient Samples.

Background: The use of pneumatic tube system (PTS) transport has gained considerable popularity in modern hospitals but is also associated with sample hemolysis. The potential contribution of PTS-associated acceleration forces to high hemolysis rates observed in the emergency department (ED) has not been investigated before and can be easily examined nowadays using smartphone applications. The first aim of our study was to investigate whether our PTS induces hemolysis of patient samples obtained from our ED.
