We all have certain types of medical equipment at home. The most common ones include a thermometer, a Blood Pressure Monitor and a Glucometer. You also add an Oximeter to your first aid kit as this can help you in measuring the oxygen saturation level.
Breathing disorders are not rare today and this is major because of air pollution. This impacts the efficiency of the lungs and it can also lead to several breathing disorders. Overall, the impact of this can be reduced by SpO2 levels. They can be fatal and this along with irregular pulse rate can even lead to death.
The oximeter can quickly help you in detecting the falling SpO2 levels and it also measures the heart rate. If you notice a sudden fall in SpO2 level then you can take the person to the hospital and you can also administer oxygen while you are on the way.
The oximeter can also be useful when you are traveling to high altitude areas like Leh and Ladakh. They can help you in quickly measuring the oxygen level and you can get first aid depending on this. The Oximeter can also help you in the early detection of some of the heart and lung diseases. Let us read more about oximeter.
How Does a Pulse Oximeter work?
The Oximeter works on a simple function which basically measures the light absorption in the blood. The fact is that there is a difference between the light absorption capabilities of oxygenated blood and the deoxygenated blood. The Oximeter basically measures the change in this light absorption and it is then converted into a readable reading which is then displayed on the screen. This difference in light absorption helps in the measurement of the SpO2 level.
The one end on the Oximeter emits light and the other end detects the light. This is the basic working principle of Oximeter. The good part is that it is a non-invasive way to measure the SpO2 levels. In addition to this, the Oximeter also measures the heart rate.
Different Types of Pulse Oximeters
There are three basic types of oximeters available in the market. You can find the details about all three of them below.
- Finger Pulse Oximeter – This is the first type of Oximeter in our list and they are usually very compact. You can mount this on the fingertip and you can mount it on any of the fingers. They are highly portable and in addition to this, you can quickly measure the SpO2 levels with the help of this Oximeter. The screen is a part of this Oximeter and it quickly measures the oxygen levels in the blood. Today, they gained a lot of popularity because of the accuracy and because of the compactness. You can find these at homes and these are also very common in hospitals now. Doctors prefer using these types of Oximeter as they are quick to give readings. This type of Oximeter is also very affordable.
- Handheld Oximeter – These are the second type of Oximeter available in the market. They are sort of expensive and they are only used by hospitals and other medical institutes. These devices are highly sophisticated and in these devices, the screen is in the form of a handheld device. The functionality of this Oximeter is not just restricted to measuring the heart rate and SpO2 levels. They can measure much more and this can be required information during the diagnostics. Also, the clip is very versatile here. It is not necessary to attach the clip to the finger, you can also attach the clip to the toe in case of an emergency.
- Paediatric Pulse Oximeter – These Oximeters are also referred to as Fetal Pulse Oximeter. These are used to check the SpO2 levels of the child. They do not have a finger clamp since the finger of the infant is very small and it can be a task to check the readings. Instead, these oximeters have a probe that can be used to measure the SpO2 levels by simply touching the probe to the head of the baby. Most of the fetal oximeters can also check the levels for the unborn baby as the probe can be inserted into the birth canal to get the reading. This helps the doctor in knowing the kind of complications that the baby can come across and they can be ready in advance.
