摘要

A patient warming apparatus (10) includes a support surface (38) for supporting a patient, a convective heater (76) for supplying convective heat to warm the patient, and a radiant heater (56) for supplying radiant heat to warm the patient. The apparatus (10) also includes a controller (200) having a first output coupled to the convective heater (76) and a second output coupl ed to the radiant heater (56) for varying output power levels of the convective heater (76) and the radiant heater (56), respectively, to maintain the patie nt located on the support surface (38) at substantially a preselected temperatu re.
