Pulse oximetry refers to a non-invasive medical practice used in monitoring the oxygenation percentage of the blood. pulse oximetry is conducted using a pulse oximeter. Pulse oximeters are made of probes which, depending on the model, are connected to an individual's ear or finger or any part of the body with sensitive blood flow. The resultant readings are then displayed on a monitor or screen. pulse oximetry can be used to calculate an individual's heart rate and blood flow. pulse oximetry can however not be used to distinguish between the different forms of hemoglobin in the body.
Pulse oximeters are commonly used during post-operative care. Working with them allows doctors to carefully monitor the recovering patient's oxygen saturation and pulse rate. With pulse oximetry, health physicians are able to reduce the risk of hypoxia before and during surgical procedures. Pulse oximeters are also invaluable devices during the treatment of patients suffering from some severe respiratory disorder.
Reading the results of a pulse oximetry exam requires some training. Pulse oximeters can be found in a wide range of sizes and designs. The results of a pulse oximetry exam may be affected by several factors. For example, patients wearing nail vanish may produce inaccurate low readings. The presence of bright lights may also create the same effect. To avoid getting the wrong diagnosis, such peripheral details must be considered with every pulse oximetry reading.
Beyond the medical walls, pulse oximeters can also be adapted to other functions. They are commonly used by mountaineers and high altitude climbers to regulate their body's oxygen level. Pulse oximeters are used by pilots who are flying unpressurized air crafts as well as athletes involved in high intensity sports. Individuals who are suffering from respiratory disorders often work with portable pulse oximeters to regulate their oxygen percentage.
Buying a pulse oximeter is fairly easy. The web is full of online retailers offering different types of device. Unless you cannot help it, it is never a good idea to rush into the purchase of a pulse meter. Finding a device that provides accurate pulse oximetry readings will require careful research.
