The present invention relates to the use of xenon in the preparation of a medicament for the treatment of neonatal asphyxia in a neonatal subject, wherein said medicament is for use in combination with hypothermia. The probe card may include a first input terminal Microelectromechanical Systems switch that connects a first input terminal and a first input probe pin, wherein the first input terminal MEMS switch comprises a control portion that receives an operation signal and a connection portion that connects the first input terminal and the first input probe pin. The reference voltage adjusting module is capable of choosing the corresponding reference voltage corresponding to the detecting result of the current detector. In one aspect, with an occluder means, a primary lumen of the catheter is used both for catheter placement and delivery of fluid. In another embodiment, the bed rail includes a relatively rigid cover depending from an upper portion of the rail portion to the sleeping surface so as to cover a gap that may exist between the first side of the mattress and the rail portion. A current reduction module can be employed to offset the bias current and to reduce a portion of the bias current from appearing in a subsequent stage to the amplifier in order to mitigate power in the subsequent stage.
