A pulse oximeter provides many benefits, especially the ability to measure blood oxygen saturation and pulse rate. However, the advantages and disadvantages of pulse oximeters cannot be separated, even though we can feel the benefits.
The advantages and disadvantages of pulse oximeters include being easy to use and able to monitor routine conditions, being less accurate in certain patients, and not being usable at low oxygen saturation.
This article will detail the key advantages and disadvantages of pulse oximeters to help clinicians and users evaluate their clinical utility.
The Advantages
Here are some of the advantages of using a pulse oximeter:
1. Easy to use
One of the advantages of a pulse oximeter is its simplicity. This tool is considered practical and easy to use. For medics, this tool is certainly an easy-to-use tool to find out information about blood oxygen saturation quickly. For personal use at home, this tool is also very easy to use.
2. Does not require invasive procedures
Not requiring invasive procedures is another advantage of the pulse oximeter. The ease of getting this tool, which you can find in many pharmacies, of course, is due to its easy use and does not require invasive procedures such as blood sampling.
3. Rapid detection
The undoubted advantage of a pulse oximeter is its ability to detect oxygen levels quickly. It only takes a few minutes when the device is placed on your finger; then you will quickly receive information about oxygen and blood saturation.
4. Can monitor routine conditions
Having a pulse oximeter, of course, will enable medical staff, or you personally, to be able to monitor your oxygen and blood saturation conditions regularly. In patients with certain respiratory conditions, if there are vital signs, this tool can help medics to be able to take action quickly.
The Disadvantages
Here are some of the disadvantages of using oximeter:
1. Less accurate in certain patients
One of the drawbacks of the pulse oximeter is its lack of accuracy in certain patients. It can be less accurate in patients with dark skin pigmentation, poor blood circulation (such as hypotension or vasoconstriction), those wearing nail polish, or false nails.
2. No early warning
No early warning is another shortcoming of the pulse oximeter. It cannot provide early warning of breathing problems before there is a significant drop in oxygen saturation.
3. Reading errors
Another thing to note about the shortcomings of a pulse oximeter is its reading errors. It can produce false readings if the probe is not attached properly, there is lighting interference, or there is excessive movement during measurement.
4. Cannot be used at low oxygen saturation
The pulse oximeter has limitations for monitoring the condition of patients with oxygen saturation below 70% and may not provide accurate results in patients with certain conditions, such as vasoconstriction or hypotension.
Clinical Application Context
Understanding the advantages and disadvantages of pulse oximeters helps us grasp why these devices are indispensable for real-time monitoring of arterial oxygen levels. What makes them ideal for use in hospitals or at home is their fast readings and ease of use.
It is important to note for clinical decision-making that pulse oximeters have a limitation: reduced accuracy under conditions of low perfusion. This has led to the gradual phasing out of traditional standalone pulse oximeters.
As the digital health ecosystem evolves, pulse oximeters have been integrated with short-range wireless modules such as Bluetooth Low Energy. This technology enables the devices to continuously transmit data to patient monitoring systems and telemetry networks.
This technology also benefits both healthcare professionals and patients. Pulse oximeters are effectively used to analyze arterial blood gases (ABG) or to determine the need for further clinical interventions.
