  • Page 21: Chapter 4 Measurement

    Chapter 4 Measurement 4.1 Measuring Principle The Pulse Oximeter is capable of measuring SpO , PR and pulse strength. The Pulse Oximeter measures SpO by a method called pulse oximetry. It is a continuous, non-invasive method based on the different absorption spectra of reduced hemoglobin and oxyhemoglobin.

  • Page 22: Precautions

    Measurement 4.2 Precautions Note Do not perform SpO monitoring and NIBP measurements on the same arm simultaneously. Obstruction of blood flow during NIBP measurements may adversely affect the reading of the SpO value. It is recommended that each measurement last longer than 15 seconds.
  • Page 23 Measurement Warning Prolonged and continuous monitoring may increase the risk of burns at the site of the sensor. If you have to use the Pulse Oximeter for Prolonged and continuous monitoring, it is especially important to check the sensor placement, and ensure proper attachment on neonates and patients of poor perfusion or skin sensitive to light.

  • Page 24: Measuring Steps

    Measurement 4.3 Measuring Steps The measurement is usually done using the adult finger SpO sensor. Palm or foot sensors may be adopted for infants. Before measurement, check the SpO sensor and its cable for damages. Do not use the sensors if any damage is found. 4.3.1 Adult Measurement Please follow the steps below to use the adult finger SpO sensor:...
