What are the major physiological effects of acidosis and alkalosis?
The principal physiological effect of acidosis is depression of the central nervous system through depression of synaptic transmission. If the systemic arterial blood H falls below 7, depression of the nervous system is so severe that the individual becomes disoriented, then becomes comatose, and may die. A major physiological effect of alkalosis is overexcitability in both the central nervous system and peripheral nerves. Neurons conduct impulses repetitively, even when not stimulated; the results are nervousness, muscle spasms a, and even convulsions and death.
Why do young children have a faster pulse rate than adults?
The short answer:The elevated heart rate is required to support the baby's rapid growth.Some DetailFetal development is dependent upon adequate exchange of gases and nutrients within the placenta. FHR (fetal heart rate) is generally about twice as high as the typical adult resting heart rate in order to support the high nutrient and gas exchange levels as well as the disposal of metabolic waste required for proper fetal development. Typical FHR in a fetus of 20 weeks averages about 155 beats per minute, with the normal range falling between 120 and 180. By term that rate has decreased, averaging 140 within a typical range of 120 to 160. By contrast, a healthy adult typically has a resting heart rate of about 80.Unusually low FHR can cause fetal acidemia, fetal acidosis and other fetal acid-base physiological problems. These, in turn often result in impaired fetal metabolism and impaired development.Throughout a person's life, typical heart rate can be seen to closely parallel rate of growth, steadily declining with the decline of growth in the mid-teens:Fetal - 20 weeks - 120-180Fetal - term - 120-160Infancy - 120-16012-35 months - 80-1103-5 years - 70-1106-12 years - 65-11013-18 years - 60-9019-61 years - 60-100**Cardio-vascular diseases account for the increased heart rates of older individuals.
Does rebreathing result in acidosis or alkalosis?
Acidosis
What would cause metabolic alkalosis to slide into metabolic acidosis?
respiratory alkalosis would cause metabolic acidosis
A student hyperventilates and is disoriented just before an exam Is this student likely to be experiencing acidosis or alkalosis?
alkalosis.
Is alkalosis the blood condition in which the blood pH is higher than normal?
Yes. Acidosis is when the blood pH is lower than normal. Alkalosis usually results from hyperventilation, whereas acidosis results from asphyxiation.
Does a baby with diarrhea sunken fontanelles dehydration bacterium induced colitis with antibiotics prescribed have acidosis or alkalosis when their pH is checked?
They would have alkalosis
What is the most common cause of acid base imbalance?
The most common cause of acid-base imbalance is respiratory alkalosis or acidosis, often due to hyperventilation or respiratory failure. Metabolic acidosis or alkalosis can also occur from conditions such as renal failure, diabetes, or dehydration.
What are the lab values you would see in someone with metabolic acidosis and alkalosis?
inbalance in ABG's
Does alcohol cause acidosis or alkalosis?
Alcohol can cause metabolic acidosis due to its influence on metabolism and disruption of the acid-base balance in the body. However, chronic alcohol use can also lead to conditions such as alcoholic ketoacidosis, which is a specific type of metabolic acidosis associated with excessive alcohol consumption.
What is the pH of blood and why?
Normally 7.4 which is neutral. Lower would be an Acidosis Higher would be an alkalosis
What is the most common cause of acid-base imbalance?
The most common cause of acid-base imbalance is respiratory acidosis or alkalosis, which occurs due to abnormal levels of carbon dioxide in the blood resulting from lung conditions such as COPD or asthma. Other common causes include metabolic acidosis or alkalosis, which result from kidney dysfunction or electrolyte imbalances.
How does the bloodstream maintain pH?
The carbonic acid and bicarbonate in the bloodstream minimize (or buffer) any trend to acidosis or alkalosis
In metabolic alkalosis does the PO2 decreases?
The PO2 does decrease in metabolic acidosis, Similarly, there is a decrease in the pH and HCO3 levels. Metabolic acidosis is a condition where the body is producing too much acid.
