Description: The oximeter is a portable medical device used to measure the level of oxygen saturation in a person’s blood. This device operates on an optical principle that assesses the amount of oxygen carried by hemoglobin in the blood. It is typically placed on the finger, ear, or earlobe, providing results within seconds. Modern oximeters are compact and easy to use, making them an essential tool in both clinical settings and at home. Their relevance has increased in recent years, especially in the context of respiratory diseases and conditions affecting oxygenation, such as COVID-19. In addition to measuring oxygen saturation, many models also provide pulse rate readings, offering additional information about the user’s cardiovascular health. Thanks to their ergonomic design and connectivity capabilities, some oximeters integrate with mobile applications and other digital health platforms, allowing for continuous monitoring and long-term data storage, facilitating personal health management.
History: The pulse oximeter was developed in the 1970s by Japanese engineer Takuo Aoyagi, who introduced the concept of using light to measure oxygen saturation in the blood. His invention revolutionized patient monitoring, allowing for non-invasive and real-time measurements. Over the years, the technology has evolved, improving the accuracy and portability of these devices, leading to their adoption in hospitals and at home.
Uses: Oximeters are primarily used in medical settings to monitor oxygen saturation in patients with respiratory diseases, during surgeries, and in intensive care units. They are also useful for individuals with chronic conditions such as COPD or asthma, as well as for athletes who wish to monitor their physical performance. At home, they are used for health tracking, especially in situations where oxygenation may be compromised.
Examples: A practical example of using an oximeter is in monitoring patients with COVID-19, where constant tracking of oxygen saturation is required to detect potential complications. Another example is its use by high-performance athletes who wish to optimize their training and recovery, ensuring that their oxygen levels are adequate during exercise.
