How to Choose a Pulse Oximeter

A pulse oximeter is a device that measures the amount of oxygen in a person's blood. It is placed on the individual's finger, and a sensor is able to give a readout. People with certain medical conditions, such as chronic obstructive pulmonary disease (COPD) or other lung ailments, may want to purchase a pulse oximeter for home use. There are a few things to consider before making your choice.

Instructions

• 1

  Keep your needs in mind. Some oximeters have alarms that can be set. This may be important for someone who is very ill, and a caregiver needs to be alerted if the oxygen level drops too low. Some devices are more appropriate for continuous use, and others are meant for spot checks.

• 2

  Consider something that is simple. There are a variety of pulse oximeters to choose from. Some have different settings to adjust for low perfusion in the body. These are mostly used in hospitals. For home use, complicated settings are usually not necessary.

• 3

  Decide if portability is important to you. Pulse oximeters vary in size. Small oximeters are easy to use and are small enough to be carried with you in a purse or coat pocket. These are a good choice for someone who needs the oximeter for a spot check.

• 4

  Get one that is battery operated if you will not be using it continuously. Larger pulse oximeters need an electrical outlet. These machines may do more and have alarms; however, they are not portable.

  Be aware prices vary considerably. Have a budget in mind. Smaller models tend to be a bit cheaper and are still accurate. Models for continuous use that have alarms and other options are more expensive.
