Pulmonary function tests (PFTs) are lung tests. They show how well your lungs work. They’re noninvasive, which means that the doctor doesn’t cut you or put any tools inside your body.

The diagnosis of pulmonary TB is definitively established by isolation of M. tuberculosis from a bodily secretion or fluid (eg, culture of sputum, bronchoalveolar lavage, or pleural fluid) or tissue (eg, pleural biopsy or lung biopsy) [ 5 ].

I27.22 is a billable ICD-10 code used to specify a medical diagnosis of pulmonary hypertension due to left heart disease. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

Pulmonary means ‘lungs’ and stenosis means ‘narrowing’, therefore pulmonary stenosis describes a condition where the pulmonary valve is very narrow. When this condition is present the muscle of the right ventricle must work harder to pump the blood through the narrow valve.

COPD (chronic obstructive pulmonary disease) is a group of lung diseases that make it hard to breathe and get worse over time. Normally, the airways and air sacs in your lungs are elastic or stretchy. When you breathe in, the airways bring air to the air sacs. The air sacs fill up with air, like a small balloon.

The pulmonary valve is one of four valves that control blood flow in the heart. It's between the lower right heart chamber (right ventricle) and the artery that delivers blood to the lungs (pulmonary artery). A diseased or damaged pulmonary valve can interrupt blood flow from the heart to the lungs.

Flash pulmonary edema (FPE) is rapid onset acute pulmonary edema. It is most often precipitated by acute myocardial infarction or mitral regurgitation , but can be also caused by aortic regurgitation , heart failure , or almost any cause leading to elevated left ventricular filling pressures .
