Abstract: A method of determining whether an individual's breathing is obstructed. The method includes measuring a transthoracic impedance of the individual over a predetermined time interval, identifying a baseline impedance and selecting an impedance cycle. The method also includes identifying a maximum impedance during the selected impedance cycle, determining an upper difference between the maximum impedance and the baseline impedance, identifying a minimum impedance during the selected impedance cycle, and determining a lower difference between the minimum impedance and the baseline impedance. The method includes determining whether an amplitude of the upper difference is less than about seventy percent of an amplitude of the lower difference, and notifying an observer that the amplitude of the upper difference is less than about seventy percent of the amplitude of the lower difference.

Abstract: A garment for swaddling a baby includes an elongate shell having an outer surface, and an inner surface opposite the outer surface defining an interior volume for receiving the arms, legs, and trunk of a baby therein. The shell has a head end, a foot end opposite the head end, lateral sides extending between the head end and the foot end, and a neck opening at the head end for receiving a neck of the baby. The garment also includes a backboard attached to the elongate shell between the head end and the foot end for preventing the baby from rolling over when the baby is swaddled within the elongate shell. The backboard includes an elongate body for supporting a trunk of the baby. The body has a first face facing the baby when the baby is swaddled within the elongate shell and a second face opposite the first face.

Abstract: A garment for swaddling a baby. The garment includes an elongate shell having an outer surface and an inner surface defining an interior volume for receiving the arms, legs and trunk of a baby therein. The garment also includes a pair of internal restraints positioned inside the interior volume of the shell. Each of the restraints receives one of the arms of the baby to retain the respective arm within the interior volume of the shell.
