This systematic review investigates whether infrared thermography (IRT) can measure systemic vasoconstriction and addresses the value of IRT in assessing circulatory deficiency and prognoses. Design was based on the PRISMA criteria and a systematic search of 6 databases was performed. 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. 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.
