what causs metabolic alkalosis?

pregnancy is a state of respiratory alkalosis?can anybody explain?

only scientific answers

Don't know anything about "respiratory alkolosis" But Alkalosis is a blood disease. So I would ask a physician before becoming pregnant. And a woman would probably have to be monitored closely throughout pregnancy.  (+ info)

By what mechanism does hyperventilation cause carpo pedal spasm ?

How does the respiratory alkalosis cause the phenomenon ?
i am interested in the role of calcium in it .

Here's your answer.

Respiratory alkalosis is a condition where the amount of carbon dioxide found in the blood drops to a level below normal range. This condition produces a shift in the body's pH balance and causes the body's system to become more alkaline (basic). This condition is brought on by rapid, deep breathing called hyperventilation.


Respiratory alkalosis is an alkali imbalance in the body caused by a lower-than-normal level of carbon dioxide in the blood. In the lungs, oxygen from inhaled air is exchanged for carbon dioxide from the blood. This process takes place between the alveoli (tiny air pockets in the lungs) and the blood vessels that connect to them. When a person hyperventilates, this exchange of oxygen for carbon dioxide is speeded up, and the person exhales too much carbon dioxide. This lowered level of carbon dioxide causes the pH of the blood to increase, leading to alkalosis.

Causes and symptoms

The primary cause of respiratory alkalosis is hyperventilation. This rapid, deep breathing can be caused by conditions related to the lungs like pneumonia, lung disease, or asthma. More commonly, hyperventilation is associated with anxiety, fever, drug overdose, carbon monoxide poisoning, or serious infections. Tumors or swelling in the brain or nervous system can also cause this type of respiration. Other stresses to the body, including pregnancy, liver failure, high elevations, or metabolic acidosis can also trigger hyperventilation leading to respiratory alkalosis.

Hyperventilation, the primary cause of respiratory alkalosis, is also the primary symptom. This symptom is accompanied by dizziness, light headedness, agitation, and tingling or numbing around the mouth and in the fingers and hands. Muscle twitching, spasms, and weakness may be noted. Seizures, irregular heart beats, and tetany (muscle spasms so severe that the muscle locks in a rigid position) can result from severe respiratory alkalosis.

Here's an amended answer. Maybe next time you should state that you wanted to know about the role of Calcium.

In addition, the alkalosis may disrupt calcium ion balance, and cause the symptoms of hypocalcaemia (such as tetany) with no fall in total serum calcium levels.

Tetany is a medical sign, the involuntary contraction of muscles, caused by diseases and other conditions that increase the action potential frequency. The muscle cramps caused by the disease tetanus are due to a blocking of the inhibition to the neurons that supply muscles and are not classified as tetany.

When the membrane potential is upset, for instance by low levels of ions (such as calcium) in the blood (hypocalcaemia), neurons will depolarize too easily. In the case of hypocalcaemia, calcium ions are drawn away from their association with the voltage-gated sodium channels thus sensitising them. The upset to membrane potential is therefore caused by an influx of sodium to the cell, not directly by the hypocalcaemia. As a result, too many action potentials are sent to muscles causing spasm.


The usual cause of tetany is lack of calcium, but excess of phosphate (high phosphate-to-calcium ratio) can also trigger the spasms. Milk-and-alkali tetany is an example of this imbalance.

Underfunction of the parathyroid gland can lead to tetany.

Low levels of carbon dioxide causes tetany by altering the albumin binding of calcium such that the ionised (physiologically influencing) fraction of calcium is reduced; the most common reason for low carbon dioxide levels is hyperventilation.  (+ info)

Can you hyperventilate w/asthma & not know it? Alkalosis?

I've been having symptoms similar to about 50 million disorders (fatigue, blurred vision, neuropathy, mental fuzziness) but all the basic diagnostic tests have come up normal. (BP & glucose & blood tests or electrolytes/blood cells).

I'm wondering if the cause of my problem is not breathing correctly. My asthma is not bad but I also feel that I subconsciously hold my breath or I inhale shallow and exhale deeply. I feel like I breathe wrong! Could this have long term, even metabolic effects? Could my diet--which is high on protein proportionately b/c I quit driniking--change my blood Ph or something. Could all this be linked? I'm going to the doctor tomorrow but I need to have some suggestions b/c she's a busy woman :) Sorry for the vague question. Any thoughts.

With regards to the causes and prevention of cardio- resiratory arrest?

Metabolic abnormalities, particularly alkalosis, are always present pre-cardiac arrest .Is this True or False

Generally speaking, alkalosis can result (if not treated correctly) in cardiac arrest....

It is more often than not the result of vomiting or diuretics...

Hope that helps..  (+ info)

When hyperventilation causes a patient to exhale large amts of CO2, the blood pH rises in a condition called?

A) Metabolic acidosis
B) Metabolic alkalosis
C) Respiratory acidosis
D) Respiratory alkalosis
E) Pulmonary distress

  (+ info)

Does anybody have a good website or information,related to arterial blood gases, interactive?

I am fairly good with the ranges, where I am slightly hung up is in respiratory alkalois or acidosis and metabolic alkalosis or acidosis and if they are compensated or uncompensated

Blood gases can be really confusing, can't they?!

I found these websites. Each is pitched a different way -- more or less academic. Try them out; i hope this helps.


this one is a video presentation:

this one costs money:

This one is a compilation of other sites, and seems pretty comprehensive:

i sure hope this helps!  (+ info)

A baby is admitted to the hospital with a history of projectile vomiting after each feeding. On examination?

it is found that the sphincter controlling food passage from the stomach to the duodenum is thickened and does not open readily. Bcause of the baby's loss of gastric juice, his blood probally indicates _______.

A) alkalosis
B) dysphagia
C) ketosis
D) acidosis

A) alkalosis

The baby is throwing up the gastric juices which are acid and therefore the body has too much base.(alkalosis) If the baby had diarrhea it would result in acidosis.  (+ info)

A patient is breathing slowly and blood pH analysis indicates an abnormally high value. What is the diagnosis?

a) respiratory acidosis
b) metabolic acidosis
c) metabolic alkalosis
d) respiratory alkalosis

  (+ info)

If a person is on ventilator and has a potassium level of 3.3 why is he at risk for Respiratory acidosis?

instead of Respiratory alkalosis?

its probably got something to do with K+ leaving the cell and taking in more H+  (+ info)
