Understanding the Importance of Pulse Oximeter
Oximetry is a way to check a person's arterial blood oxygen saturation (SpO2) and pulse rate. The two are vital signs for any patient. The device used in oximetry is called a pulse oximeter and is employed in clinics, emergency rooms, hospitals, operating rooms and even at home.
It's noninvasive, so the patient won't have to contend with needles. Moreover, a pulse oximeter is fast and can give an accurate reading in a span of seconds.
Pulse oximeters are used medically in patients who have asthma, chronic obstructive pulmonary disease (COPD), chronic obstructive airway disease (COAD), emphysema and other respiratory problems. But it's also used by pilots and mountain climbers as a way to watch out for hypoxia. Athletes also use pulse oximeters in their high altitude training.

Types of Oximeter
An oximeter is an important medical tool. There are several types of oximeters used in diagnostic procedures – fetal oximeter, finger pulse oximeter, handheld oximeter and wrist pulse oximeter.
Fetal Pulse Oximeter: This oximeter is specially designed to diagnose the baby's health. As the typical oximeter's hard to place on a newborn, the fetal pulse oximeter is designed with a probe to put on the baby's head. Light rays then get a reading from the baby's skull, giving doctors vital information about the infant's health and whether there are complications that need immediate treatment.
Finger Pulse Oximeter: The finger pulse oximeter is the most commonly used oximeter. It's similar in design to an alligator clip, with the sensor placed on either a finger or an earlobe. The infrared light then passes through the veins to record the difference between oxygenated and unoxygenated blood cells. The result appears on a screen in the clip. The pulse oximeter's portability makes it accessible, with patients able to use it at home.
Handheld Oximeter: The most sophisticated oximeter, this machine utilizes a clip that can be attached to a finger or a toe. Infrared ray passes through the clip, and a cable is connected to a screen that shows the result. The handheld oximeter shows more than the patient's oxygenated blood level.
Wrist Pulse Oximeter: The patient wears this pulse oximeter around his/her wrist. The device is designed for convenience and flexibility. It's also used for overnight monitoring of blood oxygen saturation levels. The wristwatch unit then displays the readings. The device is capable of storing up to 500 hours of data.
How to Choose the Best Pulse Oximeter
Before you buy a pulse oximeter, you need first to be certain of its use. Will you use it for checking your oxygen levels from time to time or do you have an illness that requires constant monitoring of blood oxygen levels? Once you've decided, consider the following when choosing the best pulse oximeter for you:
- Accuracy: Since the primary function of a pulse oximeter is to measure oxygen saturation and pulse rate, you want a device that's accurate to give or take 2% of actual SpO2 levels and up to 70% of oxygen saturation levels. This feature is crucial for the device to give a precise reading even when SpO2 levels are less than optimal.
- To check for accuracy: Compare your pulse oximeter with other models, like those in health clinics or your doctor's office. Remember that the accuracy of the device is also affected by motion, so if your hand has a tendency to tremble, choose a model that's tolerant of movements.
- Durability: The best pulse oximeter is durable, well able to withstand being dropped on the ground. You should also check if it's waterproof and can withstand humidity. This function is particularly crucial for oximeters used for constant monitoring.
- FDA certification: An FDA certification is required before a company can sell a pulse oximeter. While most oximeters out in the market are certified, you should do your due diligence and check with the FDA Medical Device Data Base.
- Portability: Most users prefer a pulse oximeter that's easy to carry, especially if it's being used for sport or on-the-job. If this is the case, look for a device that can be carried around the neck, placed in a pocket or clipped on a belt or holster.
- The size of sensor: Finger pulse oximeters require the user to insert a finger into the sensor and pressing a button. Check that your finger fits comfortably in the sensor. The wrong sensor size can cause the clip to either squeeze too hard or not hard enough. Opt for a device with adjustable sensors.
- Visible Display: A pulse oximeter with a bright display screen doesn't just look good, it's also essential for readings to be seen quickly and clearly. Try to choose an oximeter with a backlit display or one with adjustable brightness settings. You want one that can show the display screen clearly under any lighting conditions. Another feature to consider is a screen that can be viewed clearly from different angles.
- Weight: Just because a unit is small doesn't mean it's light. Some brands of pulse oximeters are still heavy or uncomfortable to use. Choose a device with a weight that feels comfortable for you. Remember that heavy oximeters might also be more prone to damage when dropped.
