Adolf Kussmaul referred to breathing when metabolic acidosis was sufficiently severe for the respiratory rate to be normal or reduced. [2] This definition is also followed by several other sources, [3] [4] including for instance Merriam-Webster, which defines Kussmaul breathing as "abnormally slow deep respiration characteristic of air hunger and occurring especially in acidotic states". [5]
The body normally attempts to compensate for this homeostatically, but if this fails or is overridden, the blood pH will rise, leading to respiratory alkalosis. This increases the affinity of oxygen to hemoglobin and makes it harder for oxygen to be released into body tissues from the blood. The symptoms of respiratory alkalosis include ...
One such mechanism is hyperventilation to lower blood carbon dioxide levels (a form of compensatory respiratory alkalosis). This hyperventilation, in its extreme form, may be observed as Kussmaul respiration. [16] In various situations such as infection, insulin demands rise but are not matched by the failing pancreas.
Central neurogenic hyperventilation (CNH) is an abnormal pattern of breathing characterized by deep and rapid breaths at a rate of at least 25 breaths per minute. Increasing irregularity of this respiratory rate generally is a sign that the patient will enter into coma. CNH is unrelated to other forms of hyperventilation, like Kussmaul's ...
The diagnosis of respiratory alkalosis is done via test that measure the oxygen and carbon dioxide levels (in the blood), chest x-ray and a pulmonary function test of the individual. [ 1 ] The Davenport diagram is named after Horace W Davenport a teacher and physiologist which allows theoreticians and teachers to graphically describe acid base ...
In addition to measuring the patient's respiratory rate, the examiner will observe the patient's breathing pattern: A patient with metabolic acidosis will often demonstrate a rapid breathing pattern, known as Kussmaul breathing. Rapid breathing helps the patient compensate for the decrease in blood pH by increasing the amount of exhaled carbon ...
This is a result of stimulation to chemoreceptors, which increases alveolar ventilation, leading to respiratory compensation, otherwise known as Kussmaul breathing (a specific type of hyperventilation). Should this situation persist, the patient is at risk of exhaustion leading to respiratory failure.
Kussmaul breathing – very deep and labored breathing with normal, rapid or reduced frequency seen in severe diabetic ketoacidosis (DKA). Kussmaul's sign – paradoxical rise in the jugular venous pressure (JVP) on inhalation in constrictive pericarditis or chronic obstructive pulmonary disease (COPD).
