An oxygen monitor or a pulse oximeter is a device that provides a real-time reading of a patient’s oxygen levels, blood pressure, and heart rate. The real-time reading helps doctors come with faster assessments of the patient’s health and can provide excellent assistance in determining further treatment or therapy.
Pulse oximeters are generally used by doctors, but there are at-home oxygen monitors that are designed for patients who need to monitor their oxygen levels regularly, in regards to their health status and current wellbeing.
There are different types of at-home pulse oximeters, which come in the shape of a fingertip sensor, a handheld device, or in the form of a device that is wrapped around the wrist. If you’re looking to buy an at-home oxygen monitor, we’ve got you covered.
In the following paragraphs, you’ll read all about pulse oximeters. We’ve also included a list and review of the best pulse oximeters on the market, which you can choose from. So, without further ado, let’s get started!
Oxygen Monitors: What You Need to Know Before Buying
What Are Oxygen Monitors Or Pulse Oximeters?
Pulse oximetry is a non-invasive method of monitoring one’s pulse rate and oxygen saturation. The method is done using devices known as oxygen monitors or pulse oximeters.
These are sensor devices that are placed either on the finger, the wrist (and the finger), or the earlobe to measure the oxygen and heart rate. In the case of infants, the device is placed across a foot.
How Do They Work?
Oxygen monitors provide readings using two wavelengths of the light through the body. At each change in absorbance of the wavelengths, the device detects oxygen and heart rate through arterial blood, venous blood, skin, bone, muscle, and fat.
Pulse oximeters are particularly useful in case of continuous measurement of oxygen saturation in sleep apnea or cardiovascular patients. This applies to CPAP or COPD patients, patients with sleep disorders, patients with a history of heart diseases or heart attack, etc.
Are There Different Pulse Oximeter Types?
Technically, there are several different types of oxygen monitors or pulse oximeters. The common ones are placed onto the end of a finger.
However, there are varieties that are placed on the wrist (and have a finger ring or an extension for a finger placement), as well as devices that are handheld.
The fingertip ones are the most available and fairly inexpensive, while the others (the wrist ones intended for overnight monitoring) tend to be more expensive. However, they do provide a higher level of accuracy, alongside the handheld oxygen monitors.
Can Oxygen Monitors Be Used In COVID-19 Cases?
At-home oxygen monitors have become an essential part of every household during this ongoing COVID-19 pandemic.
The oxygen monitors can play a crucial role in detecting coronavirus symptoms, for example in cases of breath shortness or heart rate issues. Even doctors use pulse oximeters increasingly when they admit possibly positive patients, to check if their oxygen levels are regular.
So, to answer the question; yes, oxygen monitors can be used in COVID-19 cases, to detect symptoms or to monitor the symptoms in patients.You can know more FAQS: Pulse Oximeters: 15 Things You Need to Know Before Buying
