Evaluating How Your Lungs Perform
Pulmonary diagnostic tests are a series of tests which evaluate how well the lungs are performing. These tests may be performed to help diagnose disease, monitor disease progression or therapeutic intervention over time, 评估残疾, or as a variable in research studies.
为参观做准备
The tests are ordered by your physician and may take anywhere from 10 to 90 minutes to perform. All results are interpreted by a board-certified pulmonologist. The referring physician should receive the results within approximately three business days of the testing.
之前测试:
- Don't use a pulmonary bronchodilator at least four hours before test time.
- If you will need to exercise, please bring sturdy walking shoes and wear comfortable clothing.
- If a metabolic test is ordered, eat only a light meal prior to the study.
Please be prepared to tell the exercise specialist the following:
- Medications you are currently taking, including inhalers, pills, or nebulizer treatments
- 药物过敏
- 健康问题
- Smoking history, including how many years you have smoked and how many packs per day
- 最近的疾病
- Any symptoms, such as shortness of breath, chest pain, dizziness, and nausea

- Spirometry (including bronchodilator responsiveness testing)
- 肺活量缓慢
- 最大自主通气
- Carbon Monoxide Diffusion Capacity
- 体积描记法/肺容量
- 单次呼吸气体稀释
- Maximal Inspiratory and Expiratory Pressure (MIP and MEP)
- Bronchial Challenge Testing (Methacholine and Exercise)
- Cardiopulmonary Exercise Testing
- 动脉血气分析
- 脉搏血氧测量
- 右至左分流
- 六分钟步行测试
肺量测定适应症
- Detect the presence of disease
- 肺部症状史
- 物理指标
- 化验结果异常
- Needed to make the diagnosis of COPD
- Quantify the extent of known disease on lung function and the progression of pulmonary disease.
Identifies people with a rapid decline in lung function - Measure the effects of occupational or environmental exposure
- Determine the benefits or side effects of therapy
- Assess risk for surgical procedures
- Evaluate disability or impairment
Indications for Pre- and Post- Bronchodilator Tests
- Assess bronchodilator responsiveness
- Evaluation of alternative drug regimens in patients with known hyper-reactive airways.
- Disability determinations when FEV1 is less than the lower limit of normal.
- Preoperative evaluation when airway obstruction is present.
肺量测定适应症
- 相对禁忌症:
- Known or suspected adverse reactions to a specific bronchodilator
- Unstable cardiovascular status that might be aggravated by beta adrenergic stimulation
Indications for Single Breath Carbon Monoxide Diffusing Capacity (DLCO)
- Evaluation of diseases which involve lung parenchyma.
- 肺气肿的评估.
- Differentiating between chronic bronchitis, emphysema, and asthma.
- Evaluation of pulmonary involvement in systemic diseases.
- Evaluation of the pulmonary effects of chemotherapy agents or other drugs known to have pulmonary toxicity.
- Impairment/disability evaluation.
肺容量适应症
- Establish or confirm a diagnosis of "restrictive ventilatory defect."
- Aid in the interpretation of other lung function tests.
- Quantify the amount of nonventilated lung before lung volume reduction surgery.
Indications for Inspiratory and Expiratory Pressures (MIP and MEP)
- Assess and quantify the degree of respiratory muscle weakness in neuromuscular disease.
- MEP may help in determining the potential for effective cough and the ability to move secretions.
- Evaluate probability of successful weaning from a ventilator.
- 相对禁忌症:
- Angina, recent MI, uncontrolled systemic hypertension.
- 最近的气胸.
- Lung biopsy within the previous week.
Indications for Methacholine Challenge Testing

- 相对禁忌症:
- FEV1 percent predicted <60%.
- 怀孕.
- 哺乳期妇女.
- Cholinesterase inhibitor medication.
Indications for Cardiopulmonary Exercise Testing with Gas Exchange Measurement
- Evaluation of unexplained dyspnea.
- Determine exercise capacity and impairment.
- Differentiate between cardiac and pulmonary causes of dyspnea.
- 康复评价.
- 术前评价.
- Impairment/disability evaluation.
Indications for 动脉血气分析
- Evaluation of ventilation, acid base balance, and oxygenation.
- Quantification of a patient's response to oxygen therapy.
- 疾病过程监测.
Indications for Six-Minute Walk Test
- Assess SpO2 at rest and with exertion in patients suspected of hypoxemia.
- Evaluate the symptom of dyspnea.
- Assess the degree of impairment.
- Evaluate therapeutic intervention.
Indications for Pulmonary 右至左分流 Testing
- Determine unexplained hypoxemia.
- Determine the extent of pulmonary A-V malformation involvement in known disease or suspected disease, e.g.遗传性出血性毛细血管扩张症,.
