acidosis,respiratory?


do you know how acidosis and the acids in the blood depress heart function?
----------

When a person's breathing becomes impaired due to certain conditions like drug overdose, severe asthma, or emphysema the body holds in too much carbon dioxiode(CO2) that you normally exhale as part of the breathing process. Too much carbon dioxide causes the blood pH level to become too acidic (normal blood pH is 7.35-7.45) and causes a state of respiratory acidosis.
How does this depress heart function? The heart is dependent on the lungs to supply oxygen to the heart for it to function normally. When theres not enough oxygen to the heart it can go into cardiac arrest pretty quickly. Thats why immediate action is needed whenever a person's breathing is compromised. Which is why Cardiopulmonary arrest is common under conditions of severe respiratory acidosis.  (+ info)

How would you expect this to affect blood ph and respiratory rate and is this a state of acidosis or alkalosis?


Patient ingested E Coli and was diagnosed with food poisoning and has had chronic diarrhea for the past 24 hours. The patient has a medical history of Chron's Disease. The diarrhea has been going on nonstop for 24 hours. How would you expect this to affect the blood ph and respiratory rate? Is the patient suffering from a state of acidosis or alkalosis and would you expect this to be related to metabolic or respiratory disorder and why?
----------

To answer this, you need more information. Renal function and pulmonary function will influence the end result. Also the activity of the Crohn's needs to be established, and whether an enteroenteric fistula is present.

However: Assuming he has non-secretory diarrhea (ie not bicarbonate wasting as in a villous adenoma of the colon), then the primary event will be a metabolic alkalosis due to volume contraction. If his kidney function is normal, he will attempt to retain sodium (along with bicarbonate) and lose potassium in the urine. Due to some fairly complex actions in the proximal and distal tubule, he will effectively retain bicarbonate, leading to the alkalosis.

If he has normal pulmonary function, he will probably not have a respiratory compensation (it would have to be hypoventilation, which is hard to do unless other things are going on (such as sedatives, altered level of conciousness etc).

As time goes by, and if the diarrhea persists, in the absence of volume replacement, he will ultimately develop pre-renal azotemia, which will affect the metabolic component (he will develop a metabolic acidosis that is distinct from the metabolic alkalosis he already has).

If he goes on to develop hypeovolemic shock, other things come into play - etc etc etc.

Its not always straighforward. I hope this helps.  (+ info)

What is the significance of a normal –high bicarbonate in respiratory acidosis?


normal high means it is still within normal range, but on the high side
----------

This means that the body is compensating for the acidosis.
Respiratory acidosis is caused when carbon dioxide is not removed from the blood due to hypoventilation, (slow breathing) or obstructions in the exchange of gases. Such conditions are caused by emphysema, asthma, bronchitis, pneumonia and pulmonary edema. Carbon dioxide increases in the blood since it cannot effectively diffuse out of the lungs.
The body has its own methods to correct abnormalities in pH.
These are referred to as "compensation" methods. In a case of respiratory acidosis, the kidneys attempt to compensate for the low pH.
The compensation is to increase excretion of H+ ion and therefore increase the retention or reabsorption of HCO3- (bicarbonate) into the blood. An increase in HCO3- ions in the blood causes the buffer equation to shift left, thus H+ ions decrease and pH increases.

Hope that answers your question. You can have compensated and uncompensated respiratory acidosis :)  (+ info)

What are the symptoms and treatment of mild or moderate respiratory acidosis?


please help me
----------

The first symptoms of respiratory acidosis may be headache and drowsiness. Drowsiness may progress to stupor and coma. Stupor and coma can develop within moments if breathing stops or is severely impaired, or over hours if breathing is less dramatically impaired.

The treatment of respiratory acidosis aims at improving the function of the lungs. Drugs that open the airways (bronchodilators, such as albuterol) may help people who have lung diseases such as asthma and emphysema. People who have severely impaired breathing or lung function, for whatever reason, may need mechanical ventilation to aid breathing.

If the patient has a depressed respiratory system from overdose, narcotic administration, or neural origins, medication can be given to treat some overdoses (morphine/fentanyl ... you would give naloxone, and ativan you would give Ramazicon). Neural origins may require mechanical ventilation to aid in breathing.  (+ info)

What is the clinical significance of normal-high bicarbonate in respiratory acidosis?


does it have to do with chronic or acute respiratory acidosis???
----------

You should only have a high bicarbonate in chronic respiratory acidosis, since your kidney regulate the bicarbonate in your body. With acute respiratory acidosis you will have a low pH, a high CO2 and a normal bicarb 22-26.  (+ info)

How does the renal system compensate for respiratory acidosis?


Respiratory acidosis is a metabolic state often seen in COPD'ers. Patients with COPD are unable to properly secrete CO2 from their blood, and in exchange, they become acidotic due to the build up of hydrogen ions. Patients with renal failure are also prone to acidosis due to the damage in their kidneys.

The kidneys are the body's main source of bicarb (HCO3) which helps to compensate (counteract) the effects of CO2. When a decrease in pH is detected, the kidneys begin to retain bicarb to compensate for the excess hydrogen ions in the blood. Unfortunately, compensation is a slow process and can often take several days.

The pH level of the blood is maintained between 7.35 and 7.45. Levels below 7.35 are considered acidotic.

CO2 (the body's "acid") ranges from 35 to 45. Levels above 45 are considered acidotic.

HCO3 (the body's "base") ranges from 22-26. Too little base results in an acidotic state. Therefore, levels below 22 are considered acidotic.

I hope this helped!  (+ info)

What is the problem with respiratory acidosis? How does the acidity cause the symptoms?


Respiratory acidosis is a condition that occurs when the lungs cannot remove all of the carbon dioxide the body produces. This disrupts the body's acid-base balance causing body fluids, especially the blood, to become too acidic.

Normal blood pH is maintained between 7.35 and 7.45 by the regulatory systems. The lungs regulate the amount of carbon dioxide in the blood and the kidneys regulate the bicarbonate. When the pH decreases to below 7.35 an acidosis condition is present. Acidosis means that the hydrogen ions are increased and that pH and bicarbonate ions are decreased. A greater number of hydrogen ions are present in the blood than can be absorbed by the buffer systems.

Symptoms and signs depend on the rate and degree of Pco2 increase. CO2 rapidly diffuses across the blood-brain barrier. Symptoms and signs are a result of high CNS CO2 concentrations (low CNS pH) and any accompanying hypoxemia.  (+ info)

Due to respiratory and metabolic acidosis?


How does the respiratory system works to re-establish the homeostasis (bring the blood pH to its normal range). Also how do the kidneys do this aswell?
----------

Hydrogen is a byproduct of cellular metabolism. It is transported in the blood by binding with HCO3 (bicarbonate) as H2CO3 (carbonic acid). This splits into H2O and CO2 by the help of carbonic anhydrase. The CO2 is eliminated by the lungs. You can equate the amount of CO2 exhaled as the amount of acid exhaled. If you breathe faster and deeper, you exhale more CO2 (acid) from the blood and your pH rises. If you quit breathing, you retain CO2 (acid) and your pH falls (acidosis). Kidneys reabsorb and regenerate HCO3 but it takes >24 hrs to do so effectively. The respiratory system is much faster. You can either have a metabolic disturbance such as lactic acidosis in which the resipratory system will increase in rate and depth to blow off CO2 to attempt to bring pH in a normal range. If the lungs are the problem, such as COPD, and CO2 isn't eliminated and pH falls. The kidneys, over time, will regenerate and reabsorb more HCO3 to a level which brings the pH into a relatively normal range.  (+ info)

Can inhaling carbon dioxide lead to respiratory acidosis?

Why is NaCl given for respiratory acidosis or any other acid-base imbalances?


It's usually only given when cardiac function is not impaired because of it AND when kidney function is adequate. Essentially, it allows the kidneys to take care of the problem by excreting either HCl or NH4Cl. Thus, the Cl is more important than the Na. Also, NaCl is often given whenever the patient needs fluids. By giving the Cl needed to help get rid of excess acids AND by giving fluids, it both helps any dehydration and give the kidneys plenty of fluids to filter out the excess acids.  (+ info)
