Asthma is a condition in which your airways narrow and swell and may produce extra mucus. This can make breathing difficult and trigger coughing, a whistling sound (wheezing) when you breathe out and shortness of breath.

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. Symptoms include breathing difficulty, cough, mucus (sputum) production and wheezing. It's typically caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. People with COPD are at increased risk of developing heart disease, lung cancer and a variety of other conditions.

Allergic rhinitis, causes cold-like symptoms. These may include a runny nose, itchy eyes, congestion, sneezing and sinus pressure. But unlike a cold, Allergic Rhinitis isn't caused by a virus. Hay fever is caused by an allergic response to a harmless outdoor or indoor substance the body identifies as harmful (allergen).

Asthma inhalers are very safe for adults and children to use

Bronchoscopy is a procedure that lets doctors look at your lungs and air passages. It's usually performed by a doctor who specializes in lung disorders (a pulmonologist). During bronchoscopy, a thin tube (bronchoscope) is passed through your nose or mouth, down your throat and into your lungs.

Pleuroscopy is a medical procedure in which an incision is made between the ribs to insert a scope (called a pleuroscope) into the pleural cavity. This is the fluid-filled space between two membranes (pleura) that surround the lungs. Pleuroscopy is a minimally invasive procedure performed under anesthesia to either diagnose a lung disease like lung cancer or tuberculosis , or treat the abnormal accumulation of fluid in the pleural space (pleural effusion).

Pulmonary function tests (PFTs) are noninvasive tests that show how well the lungs are working. The tests measure lung volume, capacity, rates of flow, and gas exchange. This information can help your healthcare provider diagnose and decide the treatment of certain lung disorders

Endobronchial Ultrasound (EBUS) What Is EBUS Bronchoscopy? EBUS (endobronchial ultrasound) bronchoscopy is a procedure used to diagnose different types of lung disorders, including inflammation, infections or cancer. Performed by a pulmonologist, EBUS bronchoscopy uses a flexible tube that goes through your mouth and into your windpipe and lungs.
