detects the level of hydrogen in expired air as an indication of intestinal bacterial fermentation of carbohydrates. It is used in the diagnosis of inflammatory bowel disease and carbohydrate malabsorption.
breath sounds
can be heard with a stethoscope on the chest and trachea. The normal sounds are the normally very faint vesicular murmur and the louder, tubular sounding bronchial tones. They are made by the air passing through the tubes of the bronchi. Adventitious (abnormal) sounds are the rale, rhonchus, grunt, friction rub, laryngeal stertor, wheeze and peristaltic sounds. Bronchovesicular sounds are intermediate between the two in character and site of origin. The vesicular sounds and the bronchial tones may be increased to the point of being an abnormality. Abnormal sounds are caused by narrowing of the tubes, collection of exudate in them or inflammation of the pleural surfaces.
breath stacking
in artificial respiration, incomplete expiration can result in residual air adding to the volume of the next inspiration with eventual over inflation of the lungs.
breath volume
may be assessed by observation of degree of chest movement and volume of expired air as felt by the hand. A respirometer is more accurate but is not available nor satisfactory for clinical use with animals unless the subject is trained to use one.

Patient discussion about breath odor

Q. What causes bad breath? I have bad breath for a long time. What causes it?

A. Here are some causes of bad breath:
A Dry mouth- Saliva helps cleanse and moisten your mouth. A dry mouth enables dead cells to accumulate on your tongue, gums and cheeks. These cells then decompose and cause odor. Dry mouth naturally occurs during sleep. It's what causes "morning breath." Dry mouth is even more of a problem if you sleep with your mouth open. Some medications as well as smoking can lead to a chronic dry mouth, as can a problem with your salivary glands.
Some Diseases can also cause bad breath- Chronic lung infections and lung abscesses can produce very foul-smelling breath. Other illnesses, such as some cancers and certain metabolic disorders, can cause a distinctive breath odor. Kidney failure can cause a urine-like odor, and liver failure may cause an odor described as "fishy." People with uncontrolled diabetes often have a fruity breath odor.
