Understanding Respiratory Diagnostic Tests: Bronchoscopy, PFTs, Spirometry, and Chest X-rays
Sputum is a mixture of mucus, dead cells, and other materials that are coughed up from the lungs. It can be used to diagnose and monitor respiratory conditions such as bronchitis, pneumonia, and asthma.
Q20. What is the purpose of a bronchoscopy ?
Ans: The purpose of a bronchoscopy is to examine the inside of the airways and diagnose or treat conditions such as bronchitis, pneumonia, tumors, and other respiratory problems. During the procedure, a flexible tube with a camera and light on the end is inserted through the nose or mouth and into the airways to visualize the inside of the lungs and airways.
Q21. What is the difference between a bronchoscopy and an endoscopy ?
Ans: A bronchoscopy is a procedure that examines only the airways, while an endoscopy examines the entire gastrointestinal tract, including the esophagus, stomach, and duodenum.
Q22. What is the purpose of a pulmonary function test (PFT) ?
Ans: The purpose of a pulmonary function test (PFT) is to assess lung function and diagnose respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other lung diseases. PFTs measure the volume and flow of air that can be exhaled from the lungs, as well as the oxygen and carbon dioxide levels in the blood.
Q23. What is the difference between a spirometer and a peak flow meter ?
Ans: A spirometer measures the total amount of air that can be exhaled from the lungs, while a peak flow meter measures the maximum speed at which air can be exhaled. Spirometry is used to diagnose conditions such as asthma and COPD, while peak flow meters are used to monitor symptoms and adjust medication in patients with asthma.
Q24. What is the purpose of a chest X-ray ?
Ans: The purpose of a chest X-ray is to diagnose and monitor respiratory conditions such as pneumonia, bronchitis, and other lung diseases. Chest X-rays can also be used to detect fluid or mass in the lungs, and to evaluate the size and shape of the heart and lungs.
Q25. What is the difference between a chest X-ray and a CT scan ?
Ans: A chest X-ray uses radiation to produce a two-dimensional image of the lungs and bones in the chest, while a CT scan uses a combination of radiation and computer technology to produce detailed three-dimensional images of the lungs, bones, and other organs in the body. CT scans are more sensitive than chest X-rays for detecting small tumors and other abnormalities in the lungs.
