Our body requires oxygen to fuel every cell and organ and keep us alive. When there is a lack of oxygen, our bodies can suffer in many ways, such as causing a person to feel dizzy, experience weakness, and even have cognitive difficulties. That’s why it’s important to monitor our oxygen levels. One of the most convenient ways to do that is by using pulse oximetry normal range. In this blog post, we’ll discuss what pulse oximetry is and how it works.

Pulse oximetry is a non-invasive method that measures the amount of oxygen in our bloodstream. It does this by using a small device that clips onto a fingertip or earlobe called a pulse oximeter. The pulse oximeter emits two types of light, red and infrared, that penetrate the skin and detect how much oxygen is in the blood. The device calculates the percentage of oxygen saturation in the blood, which is represented by a number on the display screen.

Pulse oximetry is commonly used in healthcare facilities to monitor oxygen levels in patients undergoing surgery or recovering from serious illnesses like pneumonia or asthma. The device is also commonly found in ambulances and emergency rooms as it can help quickly detect signs of respiratory distress in patients.

In recent years, pulse oximeters have become increasingly available for personal use, and many people use it to monitor their oxygen levels at home, especially those who have respiratory or circulatory problems. Athletes and people who engage in high-altitude sports like mountaineering also use pulse oximeters as an indicator of oxygen levels while exercising.

When it comes to monitoring oxygen levels, it’s important to recognize that a reading below 90% may be a sign of a serious respiratory problem, and a healthcare professional should be consulted immediately. However, it’s essential to note that not all pulse oximeters are the same. Some are more accurate than others, and readings can be influenced by various factors like skin pigmentation, nail polish, and cold extremities, which can affect the accuracy of the reading.

Another essential aspect is using it correctly. It is suggestible to use it away from artificial light of any kind, and it is more advisable to use it in a darker room. Also, this device should be used after several minutes of rest and not immediately after exercising or changing positions.

Understanding pulse oximetry and monitoring our oxygen levels is essential for our wellbeing, especially for those battling respiratory and circulatory issues. With the advancements in technology, pulse oximeters are now much more accessible to the general public, allowing individuals to monitor their oxygen levels on their own. However, it is crucial to use them correctly, ensure accuracy and maintain standards. If anyone suspects an oxygen level issue, it is always best to consult a healthcare professional. Using pulse oximetry, tracking oxygen levels can be both easy and significant, and increase awareness while striving towards healthier lives.
