入选标准
- •Participants
- •Participants will be recruited from test referrals sent to the TQEH PFT laboratory for either a 6MWT or a step test (our TQEH laboratory protocol), with the clinical purpose of determining if the patient will benefit from supplemental oxygen while on exertion (or for home oxygen”). Patients referred for testing for such clinical reasons are referred because they do not meet the national cut of PaO2 less than 55mmHg (as per a recent Arterial Blood Gas (ABG) test) and they do not automatically qualify for oxygen.
- •Patient must have had a recent ABG taken in the days leading up to the appointment (not > 4 weeks before). They must be symptomatically breathless when performing sedentary tasks, such as walking short distances, showering, making the bed, grocery shopping, etc. The patient must have seen a physician regarding the symptoms, and have been assessed as a possible candidate for oxygen therapy.
- •> PaO2 greater than 55mmHg
- •> SOB with low-level exercise
- •> Test referral for either the step test or 6MWT received at TQEH PFT laboratory with clinical questions noted on the referral as: ?benefit of oxygen”, ?home oxygen” or ?desaturation on exercise” (or similar words expressing the same clinical question).
- •> Able to complete both 6MWT and step test as per the current laboratory protocols
- •> Able to comprehend the Borg Scale for perception values
排除标准
- •Patient must not already be on exertional oxygen nor have a current oxygen prescription. They must also not have or be:
- •> PaO2 less than 55mmHg
- •> SpO2 less than 85% at rest
- •> Current smoker
- •> Sent for a 6MWT for reasons other than assessment for oxygen (ie. PAH, medication schemes, pulmonary rehabilitation assessment, etc.)
- •> Unable to complete step test requirements during testing
- •> Poor comprehension of test instructions
- •> Poor comprehension of the Borg Scale for perception values
- •> Poor SpO2 oximeter values
- •> Wheelchair or bed bound
- •> Unable to trigger the pulsed Oxygen Conserving Device (OCD) used in the step test
- •> Refusal to complete both or one of the tests
- •> Lab staff or medical staff terminate both or one of the tests early
- •> Adverse events which may include trips, falls, loss of consciousness and arousal of respiratory events
