3 Types of Pulse Oximeters

3 Types of Pulse Oximeters

1 – Fingertip Pulse Oximeter

A fingertip pulse oximeter simply clips on the fingertip of the user. This type of device will have a digital display screen and a built-in computer system which will conduct all the calculations to give you the fast and accurate readings after use. The clip which attaches to the fingertip of the user will emit light which is then measured by a sensor on the other side of the finger. The built-in computer on this device will read the amount of light which is present over many pulses or beats of the heart. The digital display will then give present the user with a reading of the patient’s blood oxygen level.

This variety of the pulse oximeter is the most common for home use. However there are a number of things to take into consideration if using one of these for your own, home use. If you are suffering with injuries to your hands or you have clots or other medical conditions on your hands then this device may not work properly.

2 – Handheld Pulse Oximeter

The handheld version of a pulse oximeter is most commonly used in hospitals and is not dissimilar to the fingertip device mentioned above. The main divergence which the handheld device is that the clip used to attach the sensor to the patient’s body is more robust and can be connected to other parts of the body such as ear lobe or toe. The device is connected to a computer which will give a more in depth analysis of the hemoglobin in the patient’s body.

3 – Foetal Pulse Oximeter

During labor, it is of paramount importance for medical staff to know the foetal haemoglobin level. But, as you could imagine, it is impossible to place a device such as those mentioned above on a baby before it has even been born. This is where a foetal pulse oximeter comes into play and saves the day.

This version of the pulse oximeter was created late on in the 1990’s and has a probe type attachment which can be used by doctors or other trained medical staff to be inserted into the birth canal and with unbelievable accuracy can be attached to the baby’s skull. This device works similar to those above but will measure the haemoglobin levels within the baby’s head.

These are the main three varieties of pulse oximeter used commonly, not only in hospital and medical establishments but also within the home and you can find more detail about them at The Review Gurus.

When you need a pulse oximeter, it is best to educate yourself about the types of pulse oximeters that are available to purchase. Once you know what types of oximeters are available, and how they work, you can then choose the one that is right for you.

1 – Fingertip Oximeter

A fingertip pulse oximeter is arguably the most common type. This, as the name suggests, is placed over the fingertip. When it is worn, it can provide you with a very accurate reading of your blood oxygen levels. It is also really easy to operate and the reading it provide is easy to decipher, so anyone can use the fingertip pulse oximeter. However, there are a couple of disadvantages of using this device. The main one is that if you are wearing nail polish, or if you have a cut in the area, it will affect the reading and you won’t get an accurate reading of your oxygen saturation levels in the blood.

2 – Wrist Pulse Oximeters

Unlike the traditional, and most common type, which I just mentioned above, wrist pulse oximeter is placed over the wrist. This is a much more convenient method of testing blood oxygen saturation levels for the reason that it means that you can still use your hands for other activities that you need to do. This type is ideal for those who have medical issues that directly affect their blood oxygen levels, and need to monitor on a frequent basis. A wrist pulse oximeter can be worn on the go as well to keep track of hemoglobin saturation. The wrist pulse oximeter won’t get in the way of other activities, so it can be worn more discreetly, and it leaves your hands free for driving or whatever other activity you may need to do.

3 – Handheld Pulse Oximeter

It is also a common type and it is more often used in a medical facility setting. It provides a highly accurate reading of a person’s blood oxygen saturation level. It is usually attached to the fingertip or the earlobe, and then a cord connects that device to a small computer with a screen. Although this type of pulse oximeter is very efficient and accurate, it is not ideal for use in a home setting for the reason that it is not as easy to operate as other types of pulse oximeters.
