Teresa Livermore got excited when her 3year old grandson Den

Teresa Livermore got excited when her 3-year old grandson Dennis ate an unknown amount of aspirin. She rushed him to the hospital for treatment. When they arrived at the emergency room, the child appeared bright and alert, but his grandmother was hyperventilating, and complained of light-headedness, and \"pins and needles\" in her hands and around her lips due to anxiety about her grandson. A quick blood-gas analysis showed Teresa\'s pCO_2 to be 28 mm Hg, and her bicarbonate was 22 mM. How does the pCO_2 value compare with normal? Rationalize why it is different. Calculate Teresa\'s blood pH. Show your work, including the equation you use to calculate this.

Solution

Answer:

Normal dose of Aspirin has been used since ancient times to relieve pain and inflammation. Now a days, aspirin is often recommended for patients who have suffered heart attacks.

Arterial Blood Gas Analysis is used to measure the partial pressures of oxygen (PaO2), which can be indirectly interpreted with partial pressure of CO2 gas, the pCO2 reflects the exchange of this gas through the lungs to the outside air.

pH is a measurement of the acidity of the blood, reflecting the number of hydrogen ions present.

pCO2 (partial pressure of carbon dioxide) reflects the the amount of carbon dioxide gas dissolved in the blood.

pCO2 reflects the exchange of this gas through the lungs to the outside air. As the person is hyperventilating will \"blow off\" more CO2, leading to lower pCO2 levels.

A normal pCO2 is 35-45 mmHg.

Below 35 is alakalotic. Hence her case pCO2 is 28mm Hg means alakalotic.

Normal bicarbonate level is 22-26 mM. Her bicarboanate was 22mM

Hence, Here the disurbances are metabolic/renal alcalotic.
