What is it?
The Lying and Standing Pulse Oximetry Test is designed to determine whether there is any difference in your Heart Rate and blood oxygen level when you are lying flat or standing upright.
How to prepare for the test
Prior to the test please ensure that you are not wearing nail varnish on your middle or index fingers as this can affect the accuracy of the test.
What is involved?
Before the test starts we will fit you with a monitor on your wrist with a probe on the end of your finger, this monitor will record your heart rate and oxygen level during the tests.
For the first part of the test you will be laying down for 10 minutes while we record your heart rate and oxygen level, for the second part of the test you will be standing up for 10 minutes and we will record the same.
During both tests we will ask you to relax and we will not talk to you as this can affect the results.
What happens after the test?
After the test your consultant will review the results and they will be discussed with you at your next clinic appointment.
