Diagnostic testing at U-Breathe


Pulmonary Function Test

The test consists of a series of non-invasive breathing maneuvers to objectively measure how well the lungs are working.


Methacholine Challenge Test
The test consists of a series of non-invasive breathing maneuvers while a small amount of inhaled medication (Methacholine) is given to test for reactive airways.


Fraction of Exhaled Nitric Oxide

A test that measures the level of nitric oxide gas in an exhaled sample of your breathe.


Arterial Blood Gas 
The test is used to check how well the lungs are able to move oxygen into the blood and remove carbon dioxide. It is a blood test that measures the acidity, levels of oxygen (O2) and carbon dioxide (CO2) from an artery.


Cardio-Pulmonary Exercise Test
The test consists of controlled exertion while monitoring breathing and vitals.


The 6 Minute Walk Test gives the doctor an objective measure of your functional capacity. It measures the distance that you can walk quickly on a flat hard surface in a period of 6 minutes. Your oxygen level is monitored during this test.

Spirometry is a physiological test that measures inhaled and exhaled volumes of air as a function of time. It is just one component of a complete pulmonary function test. 



This is measurement of breathing muscle strength using measurements of maximum inspiratory pressure (MIP or PImax), and maximum expiratory pressure (MEP or PEmax).

Maximum inspiratory pressure  and Maximum expiratory pressure 


Bronchoscopy is a procedure that looks inside the lung airways. It involves inserting a bronchoscope tube, with its light and small camera, through your nose or mouth, down your throat into your trachea, or windpipe, and to the bronchi and bronchioles of your lungs.



In a level 3 sleep study (a home sleep study) a small machine is used in the comfort of your home at night to monitor oxygen saturation, heart rate, air flow and effort while also recording details about snoring and position. It will help your doctor diagnose obstructive sleep apnea and even assess severity.

Our Team

Olga Tourin MD. |FRCPC, FACP, FCCP, Dipl ABIM (IM) |

It has been my privilege to provide care to patients who have breathing problems and suffer from various lung conditions.

Since coming to Calgary in 2004, I have been working in the field of respiratory medicine both in hospital and outpatient settings.


I believe in preventative medicine and that the biggest impact can be made during routine assessments rather than emergency care. That with timely optimal treatment, with the right medication, combined with lifestyle changes can make a lasting improvement in the quality of life and for the most part, prevent the need for acute emergency care. As such I would like to focus my efforts on providing this care in the clinic.


Let me tell you professional journey.

 Originally from Belarus, I earned my MD in 1993, and subsequently practiced respiratory medicine in Belarus. After moving to Canada in 2001, I attained certified examinations and then joined FMC (Foothills Medical Center) in this capacity. During that time I completed my residency training in Internal Medicine 2010 and subsequently in Respirology 2012, both through the University of Calgary.  I continue to attend courses, workshops, and conferences in Respirology specialty to maintain my competence to provide the most appropriate care.
