Bad breath Health Dictionary

See RESPIRATION.... breathing

Breathlessness, or dyspnoea, may be due to any condition which renders the blood de?cient in oxygen, and which therefore produces excessive involuntary e?orts to gain more air. Exercise is a natural cause, and acute anxiety may provoke breathlessness in otherwise healthy people. Deprivation of oxygen – for example, in a building ?re – will also cause the victim to raise his or her breathing rate. Disorders of the lung may diminish the area available for breathing – for example, ASTHMA, PNEUMONIA, TUBERCULOSIS, EMPHYSEMA, BRONCHITIS, collections of ?uid in the pleural cavities, and pressure caused by a TUMOUR or ANEURYSM.

Pleurisy causes short, rapid breathing to avoid the pain of deep inspiration.

Narrowing of the air passages may produce sudden and alarming attacks of di?cult breathing, especially among children – for example, in CROUP, asthma and DIPHTHERIA.

Most cardiac disorders (see HEART, DISEASES OF) cause breathlessness, especially when the person undergoes any special exertion.

Anaemia is a frequent cause.

Obesity is often associated with shortness of breath. Mountain climbing may cause breathlessness

because, as altitude increases, the amount of oxygen in the air falls (see ALTITUDE SICKNESS). (See also LUNGS and RESPIRATION.)... breathlessness

The transmitted sounds of breathing, heard when a stethoscope is applied to the chest. Normal breath sounds are described as vesicular. Abnormal sounds may be heard when there is increased ?uid in the lungs or ?brosis (crepitation or crackles), when there is bronchospasm (rhonchi or wheezes), or when the lung is airless (consolidated – bronchial breathing). Breath sounds are absent in people with pleural e?usion, pneumothorax, or after pneumonectomy.... breath sounds

A peculiar quality of the respiratory sounds heard on AUSCULTATION over a cavity in the lung.... cavernous breathing

The reverse of the normal movements of breathing (see RESPIRATION). The chest wall moves in instead of out when breathing in (inspiration), and out instead of in when breathing out (expiration). The spaces between the ribs are indrawn on inspiration – a symptom seen in children with respiratory distress, say, as a result of ASTHMA or lung infections. Patients with CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD) often suffer from paradoxical breathing; and trauma to the rib cage, with fractured sternum and ribs, also cause the condition. Treatment is of the underlying cause.... paradoxical breathing

Normal breath sounds heard in the lung by means of a stethoscope. These are soft regular sounds which become altered by disease; the changed characteristics may help the physician to diagnose a disease in the lung.... vesicular breathing

Periods during which a toddler holds his or her breath, usually as an expression of pain, frustration, or anger.

The child usually becomes red or even blue in the face after a few seconds, and may faint.

Breathing quickly resumes as a natural reflex, ending the attack.

Attacks cause no damage and are usually outgrown.... breath-holding attacks

Breath-holding attacks are not uncommon in infants and toddlers. They are characterised by the child suddenly stopping breathing in the midst of a bout of crying evoked by pain, some emotional upset, or loss of temper. The breath may be held so long that the child goes blue in the face. The attack is never fatal and the condition disappears spontaneously after the age of 3–5 years, but once a child has acquired the habit it may recur quite often.

It is important for a paediatrician to determine that such events are not epileptic (see EPILEPSY). Generally they require no treatment other than reassurance, as recovery is spontaneous and rapid – although a small number of severely affected children have been helped by a PACEMAKER. Parents should avoid dramatising the attacks.... breath-holding

A type of breathing which gets very faint for a short time, then gradually deepens until full inspirations are taken for a few seconds, and then gradually dies away to another quiet period, again increasing in depth after a few seconds and so on in cycles. It is seen in some serious neurological disorders, such as brain tumours and stroke, and also in the case of persons with advanced disease of the heart or kidneys. When well marked it is a sign that death is impending, though milder degrees of it do not carry such a serious implication in elderly patients.... cheyne-stokes breathing

Accelerated inspiration, followed by slow expiration is usually not serious. May accompany fevers and certain nervous disorders for which no specific treatment is necessary. Where condition is chronic the causal factor should be investigated. Any underlying condition should be treated. For transient irregularity:–

Teas: Balm, Motherwort, Mistletoe, Lime flowers. Tablets/capsules. Lobelia, Hawthorn, Motherwort, Valerian. ... breathing irregularities

see breath sounds.... amphoric breath sounds

the slow deep respiration associated with acidosis. [A. Kussmaul (1822–1902), German physician]

kV symbol for *kilovolt.... kussmaul breathing

a pattern of breathing seen in complete (or almost complete) airway obstruction. As the patient attempts to breathe, the diaphragm descends, causing the abdomen to lift and the chest to sink. The reverse happens as the diaphragm relaxes. It is almost always associated with use of the *accessory muscles of respiration and drawing in (recession) of the *intercostal muscles of the chest wall.... see-saw breathing

(SDB) abnormal patterns of respiration seen during sleep. *Obstructive sleep apnoea is the most common SDB; other types include central *sleep apnoea, such as *Cheyne–Stokes respiration.... sleep disordered breathing

Techniques for learning to control the rate and depth of breathing. They aim to teach people to inhale through the nose, while expanding the chest, and then to exhale fully through the mouth, while contracting the abdominal muscles. They are used after chest surgery and for people with chronic obstructive pulmonary disease (see pulmonary disease, chronic obstructive). Breathing exercises can also help people with anxiety disorders and may help to relieve symptoms in some people with asthma.

In yoga, deep rhythmic breathing is used to achieve a state of relaxation. During childbirth, breathing exercises relax the mother and also help to control contractions and reduce pain. (See also physiotherapy.)... breathing exercises
