    Pulse Oximetry01:24

    Pulse Oximetry

    Pulse oximetry, or SpO2, is a non-invasive method for continuously monitoring arterial oxygen saturation (SaO2). This procedure involves attaching a probe or sensor to the patient's fingertip, forehead, earlobe, or nose bridge. The sensor works by detecting changes in oxygen saturation levels through light signals generated by the oximeter and reflected by the pulsing blood under the probe.
    Purpose
    Average SpO2 values are greater than 95%. If the readings fall below 90%, it indicates that...

    Special considerations while measuring oxygen saturation

    Assessing respiratory rate concurrently with pulse measurement is fundamental to patient care, providing valuable insights into the patient's respiratory function. The normal breathing rate for an adult usually falls within a normal range of 12 to 20 breaths per minute. Abnormal respiratory rates can signal underlying health conditions or the need for immediate intervention.
    Ensuring accuracy in vital sign recordings while prioritizing patient comfort and minimizing anxiety is...
