If you have asthma, the inside walls of the airways in your lungs can become inflamed and swollen. In addition, membranes in your airway linings may secrete excess mucus. The result is an asthma attack. During an asthma attack, your narrowed airways make it harder to breathe, and you may cough and wheeze.
Lung cancer surgery can involve removing a portion of the lung or the entire lung. An operation to remove the lung cancer and a small portion of healthy tissue is called a wedge resection. Removing a larger area of the lung is called segmental resection. Surgery to remove one of the lung's five lobes is called lobectomy. Removing an entire lung is called pneumonectomy.
Jamil Taji, M.D., a Mayo Clinic Health System pulmonologist, discusses lung cancer:
Most pneumonia occurs when a breakdown in your body's natural defenses allows germs to invade and multiply within your lungs. To destroy the attacking organisms, white blood cells rapidly accumulate. Along with bacteria and fungi, they fill the air sacs within your lungs (alveoli). Breathing may be labored. A classic sign of bacterial pneumonia is a cough that produces thick, blood-tinged or yellowish-greenish sputum with pus.
sleep and sleep apnea
To eliminate snoring and prevent sleep apnea, your doctor may recommend a device called a continuous positive airway pressure (CPAP) machine. A CPAP machine delivers just enough air pressure to a mask to keep your upper airway passages open, preventing snoring and sleep apnea.
