Purpose: This systematic review investigates whether infrared thermography (IRT) can measure systemic vasoconstriction and addresses the value of IRT in assessing circulatory deficiency and prognoses.

Methods: Design was based on the PRISMA criteria and a systematic search of 6 databases was performed.

Results: Of 3,198 records, five articles were included. Three clinical studies were identified; two found significant correlations between IRT obtained temperatures and mortality. An experimental study found an association between peripheral temperature and stroke volume. An animal study found that central-peripheral temperature differences correlated with shock index, mean arterial pressure, and disease progression.

Conclusions: Data from the most valid study suggests that central-peripheral temperature differences should be investigated further, both on its own, and integrated with other variables.
