A full body blanket has a central bonded strip that extends front a distal end of an upper portion of the blanket to the foot end of the blanket to divide the main body of the blanket into two longitudinal portions. A discontinuous slit or tearable line is provided along the length of the strip to enable the longitudinal portions to be separable from each other by a user applying a force along the tearable strip. The strip may be torn anywhere along its entire length so that the longitudinal portion to be removed from the patient may be folded back anywhere along the length of the strip to selectively expose particular body parts of the patient. The blanket is inflated by heated air, and the heated air is circulated by channels that extend longitudinally along each of the longitudinal portions. Rows of apertures provided along the channels at the layer of the blanket that makes contact with the patient output the heated air to warm the patient.
