What is a high altitude simulation test?

This is a test that has been ordered by your physician to determine how much
additional oxygen, if any, you may need when flying or traveling to high altitudes.
Someone with lung disease may have increased oxygen needs under such
conditions.

For this test you will be in a reclined chair. A nasal canula will be placed in your
nose, a clear round hood will be placed over your head to rest on your shoulders
for approximately 30 minutes. There will be a constant flow of air delivered into
the hood through a tube to represent the oxygen level one inspires during air travel.
Your oxygen level will be monitored throughout the test by a small sensor placed
on your finger. If your oxygen level decreases to a predetermined level a small
sample of blood sample may be drawn to further evaluate the oxygen level in your
blood. Once the blood is drawn extra oxygen may be given to you until your
oxygen level is at an acceptable level.

ξ No smoking or breathing in secondhand smoke before the test.
