    is streamlining healthcare procedures such as medical monitoring. One of its latest applications is the first Bluetooth-enabled pulse oximeter, currently in development by (Hadsund, Denmark). The pulse oximeter, which measures blood oxygen saturation, merely requires that a sensor be attached to the fingertip

    saturation within blood cells. This is known as saturation or peripheral oxygen (SPO2). Figure 1 shows the block diagram of an SPO2 module in which a decompensated amplifier is used to convert the current from the photodiode into a voltage. Clever Shortcuts Minimize Design Time One of the most
  • Medical Device Link .
    a noninvasive way to measure a patient 's oxygen saturation level via wavelength measurements. In the 1980s, manufacturers of pulse oximeters introduced much smaller technology that was less expensive and easier to use. The Nellcor Pulse Oximeter (pictured) has evolved from its beginnings 25 years ago

    of 500 milliseconds. The MediceL range from City Technology Ltd. (Portsmouth, UK) includes six sensors for therapeutic applications. The sensors, which feature an internal pressure-relieving system, have a lifetime of 18 months at 100% oxygen saturation. Sensors for medical toxic gasses such as H2
