important this because proper body function can happen and we remain healthy. If your blood pH were to drop below 7.35 you would develop a condition called acidosis. Then depending on the cause of this acidosis whether it be the kidneys or the lungs would determine the kind of acidosis. If it is the kidneys causing the acidosis we would call it a metabolic acidosis, where is if it were the lungs it would be called a respiratory acidosis. Know if your blood pH for some reason would be above 7.35 you would be considered alkalosis. The cause of this would also be either the kidneys which this condition is called metabolic alkalosis and if it were the lungs it would called a respiratory alkalosis.
Metabolic acidosis occurs when your blood pH drops below 7.35 therefor making your blood acidic. When this condition is present your CO2 levels could be normal but your kidneys are not production…
given to rehydrate her. An arterial blood gas (ABG) was drawn. The results of the ABG showed an acid-base disturbance.
The patient’s acid-base disturbance was acute metabolic alkalosis. This is the most common disturbance in hospitalized patients (Thomas, 2016a). This was based on her arterial blood gas (ABG) results as well as the patient’s clinical presentation. Her pH was 7.5 (normal range 7.35- 7.45) which indicated…
The most likely cause of Connie’s respiratory alkalosis revealed in her VBG results is that when a patient is hyperventilating i.e. asthma exacerbation which causes an increase in respiratory rate, which results in the blowing off of more carbon dioxide (Larkin & Zimmanck, 2015). This is revealed in Connie’s low reading of 38mmHg for her PvC02, and as CO2 decreases so does the H+ ions in the blood which results in the alkalosis (Larkin & Zimmanck, 2015).
The nurse should encourage Connie to…
balance of the body is mainly regulated by respiratory and renal system together with the body ‘buffer system. For the body to function normally, the hydrogen ion (H+) needs to be concentrated within a narrow range, represented as pH, which determines the acidity and alkalinity of a solution. Changes in the bicarbonate (HCO3) concentration causes metabolic acidosis or metabolic alkalosis while changes in the rate of alveolar ventilation and carbon dioxide concentration decides respiratory…
demonstrated how renal system responses and reacts when subjects consuming different types of fluids. Respective fluid volumes are based on each subject’s body mass. Based on each subject’s body mass, after converted from pounds to kilograms, every subjects has different volume and fluids for ingestion. For the control subject, she ingested no fluid throughout entire lab which represented the conditions of normal fluid. For the hypotonic subjects, she ingested 854mL of water within 10 minutes…
Normal pH within the blood can range between 7.35 and 7.45 arterial and venous is 7.32 thru 7.42. Normal HCO3 for arterial is 22 thru 26 mEq/liter and venous is 19 to 25 mEq/liter with PCO2 normal for arterial 35 thru 45 mm Hg and venous 38 thru 52 mm Hg. Normal PO2 is 80 to 100mm Hg for arterial and venous is 28 thru 48 mm Hg. Acidosis can affect the central nervous system within the body and left untreated can lead to death. Alkalosis affects the central nervous system which can cause muscle…
through mechanisms in the brain, kidneys, lungs, and buffering system.
Concept Key Terms:
• Acid: any substance that has a pH less than 7.0
• Acidosis: the condition of having too much acid build up in body fluids, below 7.35
• Alkalosis: the condition of having too much alkaline build up in body fluids, above 7.45
• Anion: a negatively charge particle or ion
• Base: any substance that has a pH greater than 7.0
• Bicarbonate (HCO3): a weak base used as a buffer
• Buffer: a chemical substance…
The elevation in bicarbonate ions is due to an addition in alkali to the body which it cannot be excreted by the kidney. Metabolic alkalosis is always associated with renal impairment of some kind due to the kidneys vast capacity in excreting excess alkali. Loss of acid from the body as occurs in vomiting include metabolic alkalosis is equivalent to adding alkali to the body. (Angus MD, 2006). Excessive loss of acid from the blood, low carbon dioxide levels, and high bicarbonate levels in the…
concentration in blood. Hence its effect can be practically neglected compared to bicarbonate buffer system(pKa=6.1). The normal bicarbonate level in blood is 22-26 meq/L. The effective pH of the buffered solution can be calculated by the Henderson-Hasselbalch equation as:
pH = pKa + log10 ( [HCO3] / 0.03 x pCO2)
The general equation for the action of bicarbonate buffer is:
CO2 + H2O <==C.A.==> H2CO3 <====> H+ + HCO3-
the pH level always within the “normal” range for the human body?
6. Did the PCO2 level change during the course of normal breathing? If so, how?
No, the level stayed steadily at 40mm.
Activity 2a: Hyperventilation – Run 1
1. At 20 seconds, pH = 7.45
2. At 40 seconds, pH = 7.53
3. At 60 seconds, pH = 7.67
4. Maximum pH =7.68
5. Did the pH level of the blood change at all during this run? If so, how?
Yes, the pH level of the blood…
