sounds. Fine crackles sound like wood burning in a fireplace or cellophane being crumpled. Fine crackles usually start at the base of the lungs where there is fluid in the lungs. As the fluid fills the lungs more, fine crackles can be heard closer and closer to the top of the lungs. ...
Rales in the lungs (moist crackle sounds from the excess fluid that can be heard with a stethoscope) A gallop heart rhythm (three heart sounds instead of the normal two due to muscle weakness) Distended neck veins (The distended neck veins reflect the accumulation of blood in the veins that...
The lungsnormally inflate by increasing the size of the chest cavity, resulting in a negative (vacuum) pressure in the pleural space (the area within the chest cavity but outside the lungs). If air enters the pleural space either by a hole in the lung or the chest wall, the pressure in...
lobstersrub an antenna against the head, beetles rub a leg against the body, andcricketsandkatydidsrub one wing over another. There are other techniques for frequency multiplication. Terrestrial vertebrates use muscles to force air into and out of theirlungswhile breathing. If thin membranes are ...
The traditional method of describing speech sounds is in terms of the movements of the vocal organs that produce them. The main structures that are important in the production of speech are the lungs and therespiratory system, together with the vocal organs shown inFigure 1. The airstream from...
The air will bubble through the water, becoming moist, and deliver this moisture to the surface of the interior of the larynx, trachea, and lungs in an effective and non-irritating manner. (Editors note: Try this next time you are on an airplane. It is a great antidote to dry cabin ...
The airflow needed to produce sound comes from the lungs, and is passed through the mouth and or nose, with the glottis, tongue, and teeth being used to alter the airflow to create different sounds. Place of Articulation and Voicing In articulatory phonetics, linguists look at the place of...
The lungs normally inflate by increasing the size of the chest cavity, resulting in a negative (vacuum) pressure in the pleural space (the area within the chest cavity but outside the lungs). If air enters the pleural space either by a hole in the lung or the chest wall, the pressure ...
A-lines are artifactual repetitions of the pulmonary-pleural line displayed at regular intervals deeper to the pleura as bright, horizontal lines. They are mainly visible in normal, aerated lungs. In contrast, B-lines (also called ultrasound lung rockets) are visible in interstitial-alveolar edema...
A few hours after my son Jack was born he started breathing awkwardly. Within minutes he was taken to the NICU (neonatal intensive care unit). Quite simply, his lungs did not work properly and the doctors started a series of treatments. The doctors never figured out why. Nothing had gone...
