1 Idiopathic Pulmonary Fibrosis and Oxygen Therapy Louie Boitano, RCP Pulmonary Clinic University of Washington Medical Center

2 Effects of Idiopathic Pulmonary Fibrosis  Increases your work of breathing, by increasing elasticity of the lung tissue, causing shortness of breath with exertion. â Affects oxygenation of the blood by decreasing the movement of oxygen from the air you breathe into your lungs, through the alveolar membrane, and into the blood stream.

3 Effects of Decreased Blood Oxygenation  Further increases the work of breathing, causing increased shortness of breath, discomfort, anxiety and decreased activity.  Chronic decreased blood oxygenation has been shown to decrease life span by affecting your heart function.

4 Supplemental Oxygen Therapy  Support blood oxygenation >90%  Can decrease shortness of breath with activity and increase your level of activity.  Increase life span by decreasing the work of the heart and maintaining adequate oxygenation of the body tissues.

5 Determining The Need For Oxygen Therapy  Oximetry - a non-invasive means of measuring the percent of oxygen saturation in your blood. Can be measured while asleep, at rest and with exercise. â Arterial Blood Gas (ABG) - a sample of blood, usually taken from the artery of your wrist, is analyzed for oxygen content.

6 Supplemental Oxygen Therapy  An oxygen source provides a prescribed flow of oxygen gas measured in liters per minute. â Enriches the oxygen concentration of inhaled air to drive more oxygen into the blood.  Supplemental oxygen is considered a drug and should be prescribed according to the amount necessary to maintain the blood oxygen level > 90%.

7 Oxygen Therapy Systems  Oxygen Concentrators : separate nitrogen from the air, providing oxygen at a concentration of approximately 94-96% â Provide 1-5 liters/minute â Beneficial for night time oxygen support and daytime support within the home. â Electricity dependent; requires backup source.

8 Oxygen Therapy Systems  Continuous Flow Compressed Gas Oxygen : Usually provides 1-10 liters/minute. â Portable but not convenient; bulky cylinders. â Portable E cylinders provide only a short period of support, lpm. â Require significant storage space in the home.

9 Oxygen Therapy Systems  Portable pulse dose oxygen (liquid or gas O2) : provides 1-6 liters/min. â Most portable and convenient supply. â Conserves the O2 supply and provides the longest period of support. â Limited support due to the speed of pulse dose response in relation to a person’s breath rate.

10 Oxygen Therapy Systems  Continuous flow liquid oxygen : Provides 1-6 liters/min. â Highest oxygen support in smallest containment when used with reservoir nasal cannula systems. â Best high flow support system with progressively decreasing blood oxygenation, and when pulse dose O2 is no longer supportive.

11 Supplemental Oxygen Therapy  Can improve your quality of life by decreasing shortness of breath with activity, and maintain an improved level of activity. â Can increase your life span by decreasing the work of the heart. â Can provide support for travel and travel related activities.
