Abstract: A plethysmograph variability processor inputs a plethysmograph waveform having pulses corresponding to pulsatile blood flow within a tissue site. The processor derives plethysmograph values based upon selected plethysmograph features, determines variability values, and calculates a plethysmograph variability parameter. The variability values indicate the variability of the plethysmograph features. The plethysmograph variability parameter is representative of the variability values and provides a useful indication of various physiological conditions and the efficacy of treatment for those conditions.

Abstract: In a solenoid valve, a bobbin and a solenoid coil are accommodated in a casing. A rod-shaped plunger is slidably inserted into the bobbin. A core provided with a flow port through which a fluid flows is disposed on one side of the casing. A valve body is attached to one end opposing the flow port of the plunger. In a non-operating period during which a solenoid coil is in a non-energized state, the valve body moves away from the flow port due to the biasing force applied by the biasing portion and another end of the plunger protrudes outward from the casing through the through hole, abuts against lock portions disposed outside of the casing, and is thereby locked. The lock portions can be elastically deformed by an external force such that separation of the plunger and the valve body from the casing is allowed.
