Assessing the Accuracy of Seismofit as an Estimate of VO2 Peak in Patients With Hepato-pancreato-biliary, Colorectal, and Gastro-oesophageal Cancer

Our study aims to assess the relationship between the Seismofit derived VO2 peak estimate and CPET-measured VO2 peak in patients who are having CPET as part of their preoperative workup. Our aim is to establish whether Seismofit can be considered a cheaper, less resource intensive and better tolerated alternative to the CPET, or whether it might be useful as a screening tool to efficiently identify patients with exercise intolerance who may benefit from further characterisation by CPET.
