Buying A Pulse Oximeter
A pulse oximeter is a medical device used for measuring the amount of the oxygen in the patient's blood
. The sensor of the device is placed mainly on translucent parts of the body, which is usually a fingertip or an earlobe, providing readings to a monitor attached to the oximeter. Patients with certain medical conditions, such as chronic and obstructive pulmonary diseases or other lung disorders may need to have an oximeter with them to monitor their blood oxygenation at home. On buying such device, there are some things to consider.
Have the things that you need in mind. There are some oximeters that have alarms with them that could be set up. This may be utterly important for someone who has a serious illness, especially if he or she must be constantly monitored by medical personnel for any sudden drop of the oxygen level. Some devices are more appropriate for constant usage, while others are especially meant for carrying out spot checks and tests.
Consider something that is simple and easy to operate. There is a wide variety of pulse oximeters to choose from. Some have different settings and configurations that can be adjusted for low nutritive delivery of arterial blood to a capillary bed in the body. These types are mostly used in medical facilities. For home use, on the other and, complex settings are usually disregarded in favor of convenience of use.
Also, think upon the portability of the device. Pulse oximeters vary in size. A small pulse oximeter is easy to use and is small enough to be brought along anywhere. This is a very good choice for a patient who needs to have an oximeter for spot checks.
Purchase a battery operated oximeter if you will not be using it on a continuous basis. Larger pulse oximeters typically need an electrical outlet as power source. These machines may have additional settings and have alarms. However, they are not portable enough to be brought along.
Be aware of the standard price for a pulse oximeter. Create a budget for buying one. Smaller units tend to be a cheaper, but are accurate enough. Models for continuous usage that have alarms and advanced configurations are more expensive.
