what the risks are spirometry, pfts, spirometry, spirogram, lung function tests, pulmonary function tests, a broad range of tests, health care provider's office, a specialized facility, measure how well the lungs take in, exhale air, how efficiently they transfer oxygen, blood, spirometry measures how well the lungs exhale, information gathered, test is useful in diagnosing certain types of lung disorders, most useful, assessing, obstructive lung diseases, asthma, chronic obstructive pulmonary disease, copd, lung volume measurement detects restrictive lung diseases, in this set of diseases, a person cannot inhale a normal volume of air, restrictive lung diseases, inflammation, scarring, the lung tissue, interstitial lung disease, by abnormalities, the muscles, skeleton, the chest wall, testing the diffusion capacity, the dlco, permits an estimate of how efficiently the lungs transfer oxygen, air, bloodstream, spirometry test, a person breathes into mouthpiece that is connected to an instrument, a spirometer, spirometer records the amount, rate of air that is breathed in, out over a specified time, the test measurements, obtained by normal, quiet breathing, tests, require forced inhalation, exhalation after a deep breath, lung volume measurement, performed in two ways, most accurate way, person to sit, body plethysmograph, a sealed, transparent box that resembles a telephone booth, breathing in, out against into a mouthpiece, changes in pressure inside the box allow determination, the lung volume, lung volume, measured, a person breathes nitrogen, helium gas, a tube, specified period of time, concentration, the gas, chamber attached, tube is measured, allowing estimation, the lung volume, diffusion capacity is measured, a person breathes carbon monoxide, very short time, one breath, concentration of carbon monoxide in exhaled air is then measured, difference, in the amount, carbon monoxide inhaled, amount exhaled allows estimation of how rapidly gas, travel, lungs, blood, , not eat a heavy meal, not smoke, 4 to 6 hours, specific instructions, bronchodilators, inhaler medications, withheld, medication inhaled, children, test depends on child's age, level of trust, prepare child, toddler test, procedure preparation, 1 to 3 years, preschooler test, procedure preparation, 3 to 6 years, schoolage test, procedure preparation, 6 to 12 years, adolescent test, procedure preparation, 12 to 18 years, the test involves some forced breathing, rapid breathing, temporary shortness of breath, lightheadedness experienced, tight fitting mouth piece to breathe, nose clips, applied, test is performed to diagnose certain types of lung disease, asthma, bronchitis, emphysema, the cause of shortness of breath, to measure whether occupational exposure to contaminants affects lung function, used, administration of medications to assess effect, to measure progress in disease treatment, normal values, based upon the age, height, ethnicity, sex, the person tested, normal results, expressed, a percentage, a value, considered abnormal, less than 80%, the predicted value, abnormal results, mean that a degree of chest, lung disease present, risk is minimal, small risk of collapsed lung, a certain type of lung disease, test should not be given to a person who has experienced a recent heart attack, who has certain heart disease, cooperation, patient performing the test is crucial in providing accurate results, a poor seal around the mouthpiece, the spirometer, give poor results that, not permit interpretation, not smoke, the test.
