Testing for the evaluation of desaturation (SpO2 less than 88%) and evaluation of home oxygen need.

How Do I Schedule Testing?
To schedule an Oximetry you must have a test ordered by a physician.  To make an appointment call (509) 946-4611 ext 2655.

Who Performs The Testing
A Respiratory Therapist will perform your test.

Indications For PFT Testing
Including but not limited to:
• The need to assess saturation during exercise in patients who are clinically suspected of desaturation.
• The need to assess response to therapeutic interventions.
• The need to titrate the amount of supplemental during activity
• Preoperative assessment for lung resection or transplant
• Assess the degree of impairment for disability evaluation (pneumoconiosis, asbestosis)

When is a test contraindicated?

• Unstable angina
• Recent MI
• Aneurysm or the heart or aorta
• Uncontrolled hypertension

(cane, walker, etc.).
• The patient’s usual medical regimen should be continued.
• Patients should not have exercised vigorously immediately before the test.

What do I do during testing?
During testing you will be asked to walk along a corridor. Your oxygen level and heart rate will be monitored as you exercise. If you desaturate your may be placed on oxygen or your oxygen increased(if already wearing) to obtain a oxygen saturation of 93%.

What happens after testing?
Your physician will be given your test results the same day of testing. If you do not qualify for home oxygen your testing is complete and your appointment is complete.

If you qualify for home oxygen:
• You will be asked to choose from a list of home care providers and given their contact information before your appointment is complete.
• The home care company will be notified of your need for oxygen and will contact you to arrange delivery of all equipment.
• You will not be given equipment at the time of your appointment.
