There are multiple types of normal and abnormal respiration. They include apnea, eupnea, orthopnea, dyspnea, hyperpnea, hyperventilation, hypoventilation, tachypnea, Kussmaul respiration, Cheyne-Stokes respiration, sighing respiration, Biot respiration, apneustic breathing, central neurogenic hyperventilation, and central neurogenic hypoventilation. Each pattern is clinically important and useful in evaluating patients.   Evaluating respiratory patterns assists the clinician in understandingthe patient's current physiologic status. Abnormal breathing patterns suggest the possibility of underlying injury or metabolic derangements. Early recognition of abnormal respiratory patterns can aid the clinician in early intervention to prevent further deterioration of the patient's condition. Breathing is controlled centrally in the brainstem. It receives input from central and peripheral chemoreceptors as well as voluntary control from the cerebrum. The brainstem also receives input from the chemoreceptors and adjusts the rate and tidal volume based on pH and PaCO2. The regular cycle of breathing originates in the medulla. The medullary respiratory center has several widely dispersed groups of neurons that are referred to the dorsal and ventral respiratory groups. There does not appear to be separate inspiratory and expiratory centers. Bilateral dorsal respiratory groups (DRG) control the rhythm of breathing by producing inspiratory impulses. Neurons from this center send impulses to the motor neurons of the diaphragm and the external intercostal muscles. These nerves also extend to the ventral respiratory groups (VRG). Input from the airways, lungs, joint proprioceptors and peripheral chemoreceptors via the vagus and glossopharyngeal nerves modify the breathing pattern. Continue reading >>

Understanding The Presentation Of Diabetic Ketoacidosis
Hypoglycemia, diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar nonketotic syndrome (HHNS) must be considered while forming a differential diagnosis when assessing and managing a patient with an altered mental status. This is especially true if the patient has a history of diabetes mellitus (DM). However, be aware that the onset of DKA or HHNS may be the first sign of DM in a patient with no known history. Thus, it is imperative to obtain a blood glucose reading on any patient with an altered mental status, especially if the patient appears to be dehydrated, regardless of a positive or negative history of DM. In addition to the blood glucose reading, the history — particularly onset — and physical assessment findings will contribute to the formulation of a differential diagnosis and the appropriate emergency management of the patient. Pathophysiology of DKA The patient experiencing DKA presents significantly different from one who is hypoglycemic. This is due to the variation in the pathology of the condition. Like hypoglycemia, by understanding the basic pathophysiology of DKA, there is no need to memorize signs and symptoms in order to recognize and differentiate between hypoglycemia and DKA. Unlike hypoglycemia, where the insulin level is in excess and the blood glucose level is extremely low, DKA is associated with a relative or absolute insulin deficiency and a severely elevated blood glucose level, typically greater than 300 mg/dL. Due to the lack of insulin, tissue such as muscle, fat and the liver are unable to take up glucose. Even though the blood has an extremely elevated amount of circulating glucose, the cells are basically starving. Because the blood brain barrier does not require insulin for glucose to diffuse across, the brain cells are rece Continue reading >>
Kussmaul Breathing - An Overview | Sciencedirect Topics
Nicholas J. White, in Manson's Tropical Infectious Diseases (Twenty-third Edition) , 2014 Hyperventilation or Kussmaul's breathing (sometimes termed respiratory distress) is a poor prognostic sign in malaria. In the tachypnoea associated with high fever, breathing is shallow compared with the ominous laboured hyperventilation associated with metabolic acidosis, pulmonary oedema or bronchopneumonia. Acute pulmonary oedema (acute respiratory distress syndrome) may develop at any time in severe falciparum malaria. It is particularly common in pregnant women, but rare in children. In some cases malaria ARDS may be difficult to distinguish clinically from pneumonia. The heart sounds are normal. The central venous pressure and pulmonary artery occlusion pressures are usually normal, the cardiac index is high and systemic vascular resistance is low. This points to an increase in capillary permeability (unless the patient has been overhydrated). The chest radiograph shows increased interstitial shadowing and a normal heart size. Julian L. Seifter, in Goldman's Cecil Medicine (Twenty Fourth Edition) , 2012 Symptoms include nausea, vomiting, anorexia, polydipsia, and polyuria. Patients often exhibit Kussmaul respirations and volume depletion. Neurologic symptoms include fatigue and lethargy with depression of the sensorium. CSF exhibits a change in acid-base status with treatment of diabetic ketoacidosis. Even without bicarbonate administration, CSF pH falls as a result of the ventilatory response to the correction of acidosis and the sudden rise in Pco2. However, no correlation between decreased CSF pH and depression of sensorium has been established. Ketoacidosis is also seen in cases of starvation, in which it is generally mild and not associated with hyperglycemia. Ketoacids Continue reading >>
Cheyne Stokes Breathing And Other Abnormal Respiration
Cheyne Stokes breathing is a type of abnormal breathing. It’s characterized by a gradual increase in breathing, and then a decrease. This pattern is followed by a period of apnea where breathing temporarily stops. The cycle then repeats itself. Normal breathing, the process of moving air in and out of the lungs 12 to 20 times per minute, is something most people seldom think about. However, abnormal breathing like Cheyne Stokes is serious and may be frightening. When does it most likely occur? According to research, Cheyne Strokes breathing can happen while you’re awake, but is more common during sleep. It may happen more during non-rapid eye movement (NREM) sleep than rapid eye movement (REM) sleep. When Cheyne Stokes occurs during sleep, it’s considered a form of central sleep apnea with an extended period of fast breathing (hyperventilation). Central sleep apnea causes you to stop breathing briefly and increases the levels of carbon dioxide in your body. Cheyne Stokes is usually related to heart failure or stroke. It may also be caused by: brain tumors traumatic brain injuries high altitude sickness encephalitis increased intercranial pressure chronic pulmonary edema People who are dying often experience Cheyne Stokes breathing. This is a natural effect of the body’s attempt to compensate for changing carbon dioxide levels. While it may be distressing to those who witness it, there’s no evidence Cheyne Stokes is stressful for the person experiencing it. Both Kussmaul breathing and Cheyne Stokes breathing are characterized by fast breathing and too much carbon dioxide in the body, but that’s where their similarities end. Kussmaul breathing doesn’t alternate between fast and slow breathing or cause breathing to stop like Cheyne Stokes does. Instead, it’ Continue reading >>

[ketoacidotic Diabetic Metabolic Dysregulation: Pathophysiology, Clinical Aspects, Diagnosis And Therapy].
Abstract When glucose utilisation is impaired due to decreased insulin effect, ketones are produced by the liver from free fatty acids to supply an alternate source of energy. This adaptation may be associated with severe metabolic acidosis and tends to occur in patients with type I (insulin-dependent) diabetes mellitus. In addition, hypovolemia is an almost invariable finding with marked hypoglycemia and is primarily induced by the associated glucosuria. Ketoacidosis stimulates both the central and peripheral chemoreceptors controlling respiration, resulting in alveolar hyperventilation (Kussmaul's respiration). With the ensuing fall in pCO2 the patient tries to raise the extracellular pH. A fruity odor of acetone on the patient's breath sometimes suggests that ketoacidosis is present. The classical triad of symptoms associated with hyperglycemia are polyuria, polydipsia, and weight loss. Circulatory insufficiency with hypotension is not uncommon due to the marked fluid loss and acidemia. In more severely affected patients, neurologic abnormalities may be seen, including lethargy, seizures or coma. Some patients also have marked vomiting and abdominal pain. The history and physical examination may provide important clues to the presence of uncontrolled diabetes mellitus. Once suspected, the diagnosis can be easily confirmed by measuring the plasma glucose concentration. Glucosuria and ketonuria can be semiquantitatively detected with reagent sticks. Blood gas analysis and anion gap give objective information as to the severity of the metabolic acidosis. Therapy must be directed toward each of the metabolic disturbances: hyperosmolality, ketoacidosis, hypovolemia and potassium, and phosphate depletion. The mainstays of therapy are the administration of low-dose insulin Continue reading >>

What Is Kussmaul Breathing?
Kussmaul breathing is a deep, labored breathing pattern that indicates that the body or organs have become too acidic. The body is constantly doing work to maintain an average temperature and neutral blood acidity. To make sure this balance happens; the kidneys and cells rely on bases or buffers, chemical compounds that bind with hydrogen ions. Disruptions to these compounds cause Kussmaul breathing, which is typically associated with conditions that cause metabolic disturbances, such as kidney failure and diabetes. Contents of this article: Kussmaul breathing is a type of hyperventilation that is the lung's emergency response to acidosis. Kussmaul breathing causes a labored, deeper breathing rate. It is most commonly associated with conditions that cause metabolic acidosis, particularly diabetes. Because Kussmaul breathing is a sign of severe metabolic acidosis, which is a life-threatening condition, hospitalization is usually necessary. What is Kussmaul breathing? When the body produces or ingests too much acid; or the kidneys or lungs are failing, blood acid levels increase. If the blood becomes too acidic, acidosis occurs, and the body takes action to restore the imbalance. By using deeper, longer breaths, the lungs can expel more acidic carbon dioxide (C02) than normal. The condition takes its name from Adolph Kussmaul, the German physician who first described the breathing pattern in 1874. Symptoms As a type of hyperventilation, some people describe Kussmaul breathing as panicked breathing, where someone appears to be gasping for breath. The deep, powerful breathing associated with Kussmaul breathing often causes inhalation and exhalation to become more evident and loud. Some compare the sound to exaggerated sighing. Symptoms of acidosis Before the deep and labore Continue reading >>
What Is Kussmaul Breathing?
People with diabetes mellitus, especially type 1 diabetes and rarely in type 2 diabetes, tend to burn fatty acids which brings changes in the breathing patterns. Apart from diabetes, other forms of metabolic acidosis also result in Kussmaul breathing . The breathing is usually involuntary, in an effort by the body to get rid of unnecessary acids. Read on to find out more about Kussmaul breathing . In type 1 diabetics, when the body runs out of insulin or is not provided with enough insulin (especially during the times of excessive physical activity), it starts to burn fatty acids to produce energy. Burning fatty acids produces ketones as waste products which are released into the blood stream increasing the acidity of the blood (diabetic ketoacidosis). If the kidneys fail to discharge this excess acids through urine or if there is too many of acid units than the kidneys can process, the only way the body can reduce acidity is through respiration. In the beginning the breathing pattern is usually rapid, short, and shallow, and as the acidosis progresses it becomes slow, deep, and long to exhale the acids. This is similar to hyperventilation with characteristics of air hunger and results in a decrease in partial pressure of carbon dioxide and bicarbonate levels in the blood. The reason behind this abnormal breathing pattern is differentiated by the presence of high blood sugar levels from other forms of ketoacidosis. The presence of high blood sugar levels indicates diabetic ketoacidosis. In less severe cases of metabolic acidosis or diabetic ketoacidosis, the breathing usually comes back to normal when the blood’s composition becomes normal. Severe cases of acidosis along with this type of breathing can lead to coma. If you find yourself or someone you know suffering f Continue reading >>

What is Kussmaul Breathing? Kussmaul Breathing is the term given to a condition in which the patient builds up an extremely deep and difficult breathing pattern. This is seen mostly in individuals who are diabetic and have severe forms of metabolic acidosis, particularly diabetic ketoacidosis with kidney dysfunction. Kussmaul Breathing can likewise be clarified as a type of hyperventilation which is a condition in which an individual breathes in such a deep pattern, to the point that the level of carbon dioxide reduces in the blood, which is seen for the most part in metabolic acidosis where the breathing turns out to be more quick and shallow and as the condition exacerbates the breathing gets to be distinctly shallow and profound and it looks as though the individual is virtually gasping for breath. This kind of breathing in which the individual is essentially gasping for air is what is named as Kussmaul Breathing. Kussmaul’s Respiration There are diverse medical conditions that can influence the basic/acidic balance in your body, which means your body can turn out to be more basic or acidic. At the point when a man is acidotic, that is to say they are experiencing a pathological process (known as acidosis) that prompts to acidemia, an abnormal low pH of the blood, they may experience Kussmaul’s respiration. Kussmaul’s respiration, as German doctor Adolph Kussmaul himself portrayed, is in fact profound, slow, and labored breathing, which we now know is because of serious acidemia coming from metabolic acidosis. Nonetheless, these days, it is now and again used to portray shallow and rapid breathing examples in instances of less severe acidemia too. Reasons for this breathing pattern happening All things considered, what do you take in? Oxygen, isn’t that so? W Continue reading >>
Diabetic Ketoacidosis And Hyperglycaemic Hyperosmolar State
The hallmark of diabetes is a raised plasma glucose resulting from an absolute or relative lack of insulin action. Untreated, this can lead to two distinct yet overlapping life-threatening emergencies. Near-complete lack of insulin will result in diabetic ketoacidosis, which is therefore more characteristic of type 1 diabetes, whereas partial insulin deficiency will suppress hepatic ketogenesis but not hepatic glucose output, resulting in hyperglycaemia and dehydration, and culminating in the hyperglycaemic hyperosmolar state. Hyperglycaemia is characteristic of diabetic ketoacidosis, particularly in the previously undiagnosed, but it is the acidosis and the associated electrolyte disorders that make this a life-threatening condition. Hyperglycaemia is the dominant feature of the hyperglycaemic hyperosmolar state, causing severe polyuria and fluid loss and leading to cellular dehydration. Progression from uncontrolled diabetes to a metabolic emergency may result from unrecognised diabetes, sometimes aggravated by glucose containing drinks, or metabolic stress due to infection or intercurrent illness and associated with increased levels of counter-regulatory hormones. Since diabetic ketoacidosis and the hyperglycaemic hyperosmolar state have a similar underlying pathophysiology the principles of treatment are similar (but not identical), and the conditions may be considered two extremes of a spectrum of disease, with individual patients often showing aspects of both. Pathogenesis of DKA and HHS Insulin is a powerful anabolic hormone which helps nutrients to enter the cells, where these nutrients can be used either as fuel or as building blocks for cell growth and expansion. The complementary action of insulin is to antagonise the breakdown of fuel stores. Thus, the relea Continue reading >>
Kussmaul Breathing, Cheyne-stokes Respiration & Biot's Respiration Terms
Technical Terms for Respiration There are several weird-sounding terms related to respiration that seem harder to understand than they really are. Actually, their definitions may vary just a bit depending on setting: academic or practical. These are Kussmaul's respiration, Cheyne-Stokes respiration, and Biot's (or Bee-oh's) respiration. It all sounds kind of technical and a bit out there, but, by the end of this lesson, you'll be a pro at explaining what these are. Kussmaul's Respiration There are different medical conditions that can affect the acid/base balance in your body, meaning your body can become more acidic or basic. When a person is acidotic, that is to say they are undergoing a pathological process (known as acidosis) that leads to acidemia, an abnormally low pH of the blood, they may experience Kussmaul's respiration. Kussmaul's respiration, as German physician Adolph Kussmaul himself described, is technically deep, slow, and labored breathing, which we now know is in response to severe acidemia stemming from metabolic acidosis. However, nowadays, it is sometimes used to describe rapid and shallow breathing patterns in cases of less severe acidemia as well. Why does this type of breathing pattern occur? Well, what do you breathe in? Oxygen, right? What do you breathe out? Carbon dioxide. Carbon dioxide is acidic. It lowers the pH of the blood. By breathing rapidly and/or deeply, the body tries to blow off excess CO2 to increase pH back to normal, like an old train engine tries to blow off steam to cool itself off. Such respiration can be seen in patients with diabetic ketoacidosis or renal (that is to say, kidney) failure among other problems. Cheyne-Stokes Respiration The next form of respiration I want to get to is a bit more difficult to understand, but Continue reading >>

Kussmaul Breathing: Pathophysiology, Causes And Treatment
Kussmaul breathing: Pathophysiology, Causes and Treatment by Dr. Cameron Troup MD in Respiratory Diseases Definition: it is a very dangerous symptom that accompanies the conditions associated with the alteration of the organs and the acidification of the organism. Kussmauls breathing is described as slightly faster breathing with extenuating deep breaths.It is a reflexive reaction of the organism and is usually present in unconscious patients. Kussmauls breathing is the name given to a condition in which the patient develops an extremely deep and laborious breathing pattern. This is mainly observed in people who are diabetic and have severe forms of metabolic acidosis, especially diabetic ketoacidosis with renal dysfunction. Kussmauls breathing can also be explained as a form of hyperventilation . That is, it is a condition in which an individual inhales in a pattern so deep that the level of carbon dioxide decreases in the blood, which is seen especially in metabolic acidosis where breathing becomes extremely rapid and shallow and as the condition worsens the breathing becomes shallow and deep. It seems as if the individual is practically panting to breathe. This type of breathing pattern was first described by Adolph Kussmaul, a German physician in 1874. He realized that his patients with diabetic ketoacidosis had a breathing pattern that was first labeled as having air hunger. In Kussmauls type of breathing, the patient breathes a lot, that is, it is a hyperventilation along with tachypnea.So were going to find that the amplitude of the breaths along with the rate will increase.There are usually no pauses between breaths. This is not specific for diabetic ketoacidosis.It can also appear in other types of severe metabolic acidosis, for example, alcoholic ketoacidosis Continue reading >>
