The purpose of a pleural rub is to hear things on the inside of one's body. For example a machine that can hear the sounds inside a person's lungs when they are breathing to see if things sound normal or if there is a noisy rattling in the lungs, which would cause concern for one's health.
pleural rub
That sound is called a pleural friction rub and is typically heard as a grating or rubbing noise during respiration. It is often a sign of inflammation of the pleura, which can be due to conditions such as pneumonia or pleurisy.
A pericardial friction rub is heard best at the lower sternal border and may change with patient position. It is associated with pericarditis. A pleural friction rub, on the other hand, is heard best at the anterior axillary line and changes with breathing. It is associated with pleuritis.
The grating sound produced by friction of the pleural surfaces rubbing against each other is known as pleural friction rub. It is commonly heard in conditions like pleurisy and can be described as a creaking or grating sound that is typically heard during both inspiration and expiration. Pleural friction rub can indicate inflammation of the pleura and is generally associated with pain on breathing.
Pleural effusion is excess fluid that accumulates between the two pleural layers, the fluid-filled space that surrounds the lungs. Excessive amounts of such fluid can impair breathing by limiting the expansion of the lungs during ventilation.
It prevents a pleural friction rub. Its like a lubricant for the lungs to move up and down without any friction.
If the pleural membrane secretes too much fluid, it can build up in the pleural space, causing a condition called pleural effusion, which can put pressure on the lungs and limit their expansion. If the pleural membrane doesn't produce enough fluid, it can lead to a condition called dry pleurisy, causing the pleural layers to rub against each other and result in pain and inflammation.
what is pleural thickening
1.hot water on your head (dont splash it just rub it) 2.rub your head as fast as you can.
pleural membrane
Pleural cavity is the potential space. There is no gap between the outer and the inner pleura. There is very little fluid in the pleural cavity. You have negative pressure in the pleural cavity.
