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.
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
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
