Pulse oximeter Flashcards
What is a pulse oximeter used for?
To measure and monitor SpO2(Oxygen saturation)
When to use a pulse oximeter?
1.On all children on admission
2.On all very sick children
3.On any child who is deteriorating
4.On any child with respiratory difficulties
5.On any child with cardiac disease
Describe how a pulse oximeter works?
-It consists of infra-red LED in the probe
-By recording the amount of light being absorbed the pulse oximeter measures the % of blood bound with oxygen.
What is the normal SpO2?
90-100% on room air.
In what conditions is it difficult to measure SpO2?
When the hand or foot are cold.
Describe ways in which you can ensure the pulse oximeter gives accurate results?
1.Check the wave form
2.Ensure the HR corresponds to the manual pulse rate
3.Ensure tissue is well perfused in the assessment extremity.
4.Ensure saturation is within measurement limit of pulse oximeter(70-100%)
What is the normal SpO2 for patients on O2?
90-95%
What is the normal SpO2 for patients off O2?
90-100%
What is considered an inaccurate SpO2?
A saturation below 70%
Describe how you can get a good pulse wave?
1.Choose the right probe
2.Minimize patient movement
3.Avoid strong light
4.Use a warm and pink extremity.
5.Ensure the neonatal setting is used(or an alarm may sound when the HR or SpO2 are actually in an acceptable range)
What are some of the things you should consider before documenting results/How do you ensure a reliable a saturation reading?
-Check if HR reading and manual pulse count agree
Assess whether or not the SpO2 reading is what you expected from patient’s clinical condition
Describe ways you can prevent infection?
1.Clean your hands with soap and water or alcohol before and after handling materials that will used on a patient.-
2.Disinfect probe site on patient and probe.
3.Always wipe the pulse oximeter with alcohol between patients
4.Do not sumerge pulse oximeter in alcohol
5.Do not put pulse oximeter in the bassinet
6.Do not touch other objects after cleaning hands
List some of the complications faced when using a pulse oximeter?
1.Misdiagnosis due to poor trace
2.Pressure sore or skin damage
3.Patient movement disrupting measurement
5.Strong light interference
What must be done when the Spo2 is less than 90%.
The patient should be considered for supplemental oxygen therapy.
Describe ways in which you can care for the pulse oximeter?
1.Make sure it charged.
2.Store in a clean,dry place where it won’t be lost or is accessible.
3.Prevent infection by wiping your pulse-ox between uses.
