A pulse oximeter is a useful tool for nurses, doctors and a variety of professionals in the healthcare field. The science of pulse oximetry is used to measure a patient's oxygen saturation level in the blood. With the help of a finger pulse oximeter, medical workers can obtain key health information from their patients in a noninvasive and painless way. While these devices are often used during medical exams, they are also helpful for evaluation during surgery and after sedation. The pulse oximeter is a clip-like device that uses light to measure blood oxygen levels. These oximeters are tools that can help nurses to find out whether a ventilator is needed for breathing or if a patient can increase their level of activity. They are also useful because they can help doctors to check the health of a person with a condition that affects blood oxygen levels, like heart failure, heart attack or pneumonia. Pulse oximeters are essential diagnostic devices for people with chronic obstructive pulmonary disease (COPD), lung cancer and asthma. Since it is compact and convenient, you can take the pulse oximeter with you anywhere. Affordable models allow you to keep one in your medical bag and one at home. You can even store one in your office desk. Purchase them in different colors to match your scrub uniform or the branding of your practice. Whether you are a nursing student, a registered nurse or a physician, it helps to have your own medical grade pulse oximeter.
