• What is pulse oximetry?
• Parts of pulse oximetry
• Need of pulse oximetry
• Risks of pulse oximetry?
• How to take a reading
• Advantages and disadvantages of pulse oximetry

4. What is pulse oximetry?
• Pulse oximetry is a test used to measure the oxygen level
(oxygen saturation) of the blood.
• It is an easy, painless measure of how well oxygen is being
sent to parts of your body furthest from your heart, such as
the arms and legs.
• A clip-like device called a probe is placed on a body part,
such as a finger or ear lobe.
• The probe uses light to measure how much oxygen is in the
blood.
• This information helps the healthcare provider decide if a
person needs extra oxygen.

5. Parts of pulse oximetry

6. Need of pulse oximetry
Pulse oximetry may be used to see if there is enough
oxygen in the blood. This information is needed in many
kinds of situations. It may be used:
• During or after surgery or procedures that use sedation
• To see how well lung medicines are working
• To check a person’s ability to handle increased activity
levels
• To see if a ventilator is needed to help with breathing, or
to see how well it’s working
• To check a person has moments when breathing stops
during sleep (sleep apnea)

7. Risks of pulse oximetry?
All procedures have some risks. The risks of this
procedure may include:
• Incorrect reading if the probe falls off the earlobe,
toe, or finger
• Skin irritation from adhesive on the probe

8. How to take a reading
• To take a reading with a pulse oximeter, you will:
1.Remove any jewelry or fingernail polish on your finger if
measuring from this location.
2.Make sure your hand is warm, relaxed, and below heart
level if attaching the device here.
3.Place the device on your finger, earlobe, or toe.
4.Keep the device on for as long as needed to monitor
your pulse and oxygen saturation.
5.Remove the device once the test is over.

10. SUMMARY
We have learned about What is pulse oximetry?,
Parts of pulse oximetry, Need of pulse oximetry,
Risks of pulse oximetry?, How to take a reading
and Advantages and disadvantages of pulse
oximetry.

11. Conclusions
Pulse oximetry is universally used for monitoring respiratory status
of patients in the ICU. Recent advances in signal analysis and
reflectance technology have improved the performance of pulse
oximeters under conditions of motion artifact and low perfusion.
Multiwavelength oximeters may prove to be useful in detecting
dyshemoglobinemia. Monitoring with pulse oximetry continues to
be a critical component of standard of care of critically ill patients
despite the paucity of data that such devices improve outcome.
