A study by Woods et al was undertaken in patients with shock with the aim to establish if a correlation exists between core/peripheral temperature gradients and measured haemodynamic status using a pulmonary artery catheter.Patients with hypovolaemic, septic and cariogenic shock were included in the study.

They concluded that there was no such correlation and suggest  “In addition, no predictable assessment of progress in individual patients can be based on changes in the gradient.”

​They also added “It is irrational and dangerous to proceed with the treatment of shock, using temperature gradient as a measure of the patient’s heamodynamic status”.
