ABSTRACT:
Device and method for testing the accuracy of pulse oximeters used in estimating arterial blood saturation levels. The device is for use in enabling a pulse oximeter to measure the absorption of the radiation emitted by the oximeter by a pulsatile liquid contained within the device, which device comprises the liquid, a resiliently flexible displaceable member adjacent the liquid which in operation is made to rhythmically move with a steady frequency and amplitude so as to effect a change in the depth of a volume of liquid in the direction acted upon by the radiation such that the liquid is operably provided in pulsatile form while under the influence of the radiation. The device provides a cheap and convenient method of testing the accuracy of the pulse oximeters.
