    • There is provided a method of assessing the reliability of a measurement of blood pressure of a subject, the method in a control unit of an apparatus comprising obtaining a first measurement of at least one physiological characteristic of the subject that is indicative of the level of pain and/or stress of the subject, wherein the first measurement is made prior to a measurement of blood pressure being made; obtaining the measurement of blood pressure of the subject; obtaining a second measurement of the at least one physiological characteristic of the subject, wherein the second measurement is made after the measurement of blood pressure is made and prior to a subsequent measurement of blood pressure being made; and determining if the measurement of blood pressure is reliable based on the first measurement and the second measurement, wherein the measurement of blood pressure is determined to be reliable if the first measurement and the second measurement indicate a low level of pain and/or stress. A corresponding apparatus that implements the method is also provided.

    • A system and method comprising a pulse oximeter with a pulse width modulator that periodically tests the wavelengths emitted at the pulse width's upper and lower limits in order to ensure that the median pulse width is emitting the wavelength specified by the manufacturer. The system comprises a pulse oximeter that has LED emitter(s), photodetectors, a pulse width modulator and memory. The specifications database contains data relating to the wavelength specified by the manufacturer. The calibration software will periodically test the LED to ensure the correct wavelength is being emitted by the LED in order to detect the proper constituents in the patient's blood. The testing is conducted whenever the pulse oximeter is energized and then again at a specified interval until power is disconnected from the pulse oximeter. Each test includes increasing the pulse width until an error is detected, recording the upper limit of the pulse width and the corresponding wavelength before an error occurred. Then performing the same test by decreasing the pulse width until an error is detected. The wavelength emitter at the median pulse width is then calculated and compared to the manufacturer's specification. If they do not match the calibration software adjusts the pulse width until the manufacturer's specification is achieved.
    • 包括具有脉冲宽度调制器的脉冲血氧计的系统和方法,所述脉冲宽度调制器周期性地测试在脉冲宽度的上限和下限处发射的波长,以确保中值脉冲宽度发射由 生产厂家。 该系统包括脉冲血氧计,其具有LED发射器,光电探测器,脉宽调制器和存储器。 规格数据库包含与制造商指定的波长相关的数据。 校准软件将定期测试LED,以确保LED发出正确的波长以检测患者血液中的适当成分。 只要脉搏血氧饱和度测定仪通电,然后再按指定的间隔再次进行测试,直到脉搏血氧仪断电为止。 每个测试都包括增加脉冲宽度直到检测到错误,记录出现错误之前的脉冲宽度上限和相应的波长。 然后通过减小脉冲宽度来执行相同的测试,直到检测到错误。 然后计算中值脉冲宽度处的波长发射器并与制造商的规格进行比较。 如果它们不匹配,校准软件会调整脉冲宽度,直到达到制造商的规格。
