The cranial orthosis (10) is preferably contoured to match the curvature of the fronto-temporal, parietal and occipital areas (24, 26, 28, 30) of an infants cranial vault to provide protection against the acquisition of postural cranial deformities as a result of the infants sleeping in the supine position. The orthosis (10) is designed to be of universal fit, as determined by the infants fronto10 occipital head circumference (FOC) measurement. The interior dimensions of the orthosis (10) can be enlarged to accommodate growth of the infants head without requiring replacement. The sensor (70) may detect oxygen saturation, pulse, temperature, or any other measureable condition or combination of conditions. The system (72) includes an alarm (112) that is triggered when a sensed condition crosses a selected 15 threshold level.1/11 10 12 30 14 28 16 28 14 10 18 20 , 12 30 FIG. 1 FIG. 2 30 46 30 10 10 20 20 18 . -- 18 FIG. 3 FIG. 4 28 32 18 30 10, 16 /-46 1 36 ~ -: 4 22 12i 34 24 26 FIG. 5
