WHAT IS? (in simple speak)
Aveloi - Tiny air sacs found at the end of the smallest airways where oxygen and carbon dioxide is exchanged.
Anti Inflammatory - A medicine or drug used to help fight inflammation
Arterial Blood Gas (ABG): A blood test that measures the level of oxygen, and carbon dioxide in the blood.
Bi Level Positive Airway Pressure (BiPAP): A small non-invasive breathing machine, using two pressure levels, inspiration and expiration, to help with breathing. It's connected to tubing and a facemask which is worn by the patient.
Body Box: (another name for Plethysmograph) - A clear, airtight chamber (resembling a telephone booth or helicopter) which you sit in and perform breathing tests (PFT's)
Bronchodilator: Medicines that are used to help relax the muscle areas of the airways thus helping to increase the flow of air.
Bronchospasm: The tightening of the areas of muscles surrounding the airways which in turn causes these same airways to become narrower. Shortness of breath and/or wheezing may ensue.
Carbon Dioxide: An odorless and colorless gas, naturally produced in the body's tissues, which is exchanged in the lungs with oxygen and removed.
Chronic Bronchitis - There must be a productive cough for most days over 3 months for at least 2 years in a row.
Continuous Positive Airway Pressure (CPAP): A machine that assists with breathing by using pressure to keep the airways open.
Cor pulmonale: When the right side of the heart is weakened and enlarges thus causing more shortness of breath and leg and foot swelling. This can happen with low oxygen levels.
Diaphragm and Diaphragmatic Breathing : The diaphragm is located just under the lungs and can be very effective for breathing. It uses less effort and energy than the upper body.
(DLCO): A measurement which shows how much oxygen is carried or transferred into your blood stream.
Diuretic: A type of medicine used to help increase the output of water from the body.
Dry Powdered Inhaler: A device that uses "dry powder" in an inhaler.
Dyspnea: Being short of breath
Edema: Swelling/fluid retention
Electrocardiogram (EKG aka ECG): A printout from an ECG machine that follows/charts the electrical activity of the heart.
Exacerbation: A flare up and/or worsening of a disease or condition
Forced Vital Capacity (FVC):
The maximum amount of air you can exhale
the maximum amount you can exhale in 1 second
GERD: Gastroesophageal Reflux Disease. A condition whereby the stomach "backs up" or "regurgitates" into the esophagus.
Hypoxemia - Low blood oxygen level
A procedure whereby part of the lung (a lobe) is removed
Lung Volume Reduction Surgery (LVRS):
A procedure whereby diseased portions of the lung is removed to make way, or provide room for, parts of the lung(s) that are still healthy.
Normal Saline :A solution made of salt and water
Pulmonary Function Test (PFT): A breathing test (more thorough than Spirometry) which shows the lungs functionability.
Pulse Ox: A device that measures your heart rate and the amount of oxygen in your blood
Pursed Lip Breathing: A method to assist in breathing and reduce shortness of breath (SOB)
Residual Volume: The amount of air trapped or unable to expel.
Sleep Apnea: A sleep disorder whereby a person's breathing stops for a short period of time. This "non breathing period" usually lasts between 10 and 20 seconds and can occur 20 - 30 in an hour.
Spirometry: A non invasive test which measures lung function.
Transtracheal Oxygen Therapy (TTO):
A method to deliver oxygen by a small tube which is surgically inserted into the lower neck. (Some people prefer this over the nose tube)
Ventilator: (also known as a respirator) A ventilator is an automatic machine which mechanically assists patients to breathe when they cannot breathe on their own.
