Healthy livestock breathing patterns Features: Coordinated movement of chest and abdomen ups and downs, high intensity

It is a pathological breathing pattern (except for dogs) characterized by: obvious undulations of the chest wall and slight abdominal wall movements, indicating disease in the abdominal wall and abdominal organs.

It is a pathological breathing pattern characterized by: the ups and downs of the abdominal wall are particularly obvious, while the movement of the chest wall is slight, indicating disease in the lungs, pleura and chest wall of the chest.

Characteristics: Exhalation is extremely laborious and the exhalation time is prolonged. It shows: poor airflow, narrowed bronchi, and reduced lung elasticity. Seen in: chronic alveolar emphysema, bronchiolitis, pleuropneumonia, etc.

Characteristics: Multiple short and intermittent breathing movements when inhaling or exhaling. Seen in: Pulmonary disease and painful thoracoabdominal disease

Characteristics: Breathing gradually deepens and speeds up. After reaching the peak, it gradually becomes shallower and slower, and then the breathing is interrupted. After that, the above method is repeated, showing a wave-like rhythm. Commonly seen in: chest inflammation, uremia, heart failure.

Characteristics: Several consecutive deep breaths of approximately equal depth and apnea occur alternately, that is, indirect deep breaths. Example: The condition is severe and the respiratory center is extremely exhausted, which is more serious than Cheyne-Style breathing.

Characteristics: Breathing is not interrupted, deep and slow breathing occurs, breathing is significantly prolonged, the number of breathing is reduced by 3-4 times/min, and there are obvious breath sounds during breathing.

Features: Significantly prolonged inspiratory phase Example: Upper airway stenosis Commonly seen in: nasal stenosis, laryngeal edema, pharyngitis, porcine infectious atrophic rhinitis, chicken infectious laryngotracheitis

Characteristics: Exhalation is laborious and expiration time is significantly prolonged. It shows that the elasticity of lung tissue is weakened and the bronchioles are narrowed, making it difficult to remove air from the alveoli. Common in: acute bronchiolitis, chronic emphysema, pleuropneumonia

type

Cause

A soft blowing sound, which can be heard during the inhalation and early exhalation phases and is clearest at the end of the inhalation. Auscultation location: most obvious in the middle 1/3 of the lung area

It is formed by the vortex produced when the air flows through the glottis fissure.

Increased universality

Limitation enhancement

Not enough air entering the alveoli

Reduction or loss of lung tissue function

Breath sound conduction disorder

It shows: there are small inflammatory symptoms in the lungs, the small bronchi are narrowed, and the air cannot enter the lungs uniformly.
