Impulse oscillometry (IOS), also known as respiratory oscillometry, forced oscillatory technique (FOT), or just oscillometry, is a non-invasive lung function test that measures the mechanical properties of the respiratory system, particularly the upper and intrathoracic airways, lung tissue and chest wall, usually during the patient's tidal breathing (the way someone breathes when they are ...
Total lung capacity: the volume in the lungs at maximal inflation, the sum of VC and RV. TV Tidal volume: that volume of air moved into or out of the lungs in 1 breath (TV indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.)
Lymphocytic interstitial pneumonia (LIP) is a syndrome secondary to autoimmune and other lymphoproliferative disorders. Symptoms include fever, cough, and shortness of breath. Lymphocytic interstitial pneumonia applies to disorders associated with both monoclonal or polyclonal gammopathy. [1]
White lung syndrome, or white lung pneumonia, is getting attention after an outbreak in Ohio. Experts explain symptoms, causes, treatment, and prevention.
In this Feb. 9, 2018, file photo, a radiology technician looks at a chest X-ray of a child suffering from flu symptoms. As we enter the time of year when more illnesses start to circulate ...
Rapid breathing helps the patient compensate for the decrease in blood pH by increasing the amount of exhaled carbon dioxide, which helps prevent further acid accumulation in the blood. [11] Cheyne–Stokes respiration is a breathing pattern consisting of alternating periods of rapid and slow breathing, which may result from a brain stem injury ...
Pulmonary Function Testing (PFT) allows for the evaluation and assessment of airways, lung function, as well as specific benchmarks to diagnose an array of respiratory tract infections. [10] Methods such as gas dilution techniques and plethysmography help determine the functional residual capacity and total lung capacity. [ 10 ]
Crackles are the clicking, rattling, or crackling noises that may be made by one or both lungs of a human with a respiratory disease during inhalation, and occasionally during exhalation. They are usually heard only with a stethoscope ("on auscultation"). Pulmonary crackles are abnormal breath sounds that were formerly referred to as rales. [2]
