Consider the cigarette smoke contain an average of 450 ppm carbon monoxide. If the average oxygen content in the air in the lungs is 19%, what percentage of the saturation level would the COHb concentration ultimately reach?
Please provide the calculation
Diabetic ketoacidosis is characterized by an increased level of ketone bodies, which causes metabolic acidosis. A patient in diabetic ketoacidosis will have an altered rate of ventilation. Will the patient be hyperventilating or hypoventilating? How will a change in the rate and depth of ventilation compensate for an acidosis that is metabolic in nature?
A patient accidentally swallows 4 pills of Ipecac, a known emetic. He then suffers the consequence, with one effect being hypochloremia. His blood gas results show an increased pCO2, increased pH, and increased bicarbonate levels as his body tries to correct the condition. Which of the following is the body's response to the condition stated above and as mirrored by the blood pH and gas analysis?
metabolic correction of respiratory alkalosis
metabolic correction of respiratory acidosis
respiratory correction of metabolic alkalosis
respiratory correction of metabolic acidosis

- Individuals with cystic fibrosis produce thick mucus in the lungs, resulting in a higher-than-normal level of CO2 in the blood. What is the problem that results from higher-than-normal levels of COz in the blood? Please relate this to buffers in the blood and construct a clear problem statement.arrow_forwardExposure to air containing 600 ppm CO for 30 minutes results In an actual HbCO blood concentration of 10%. Estimate the percentage of the equilibrium saturation value of HbCO.arrow_forwardWhen travelling high altitude, one of the problem is alkalosis of the blood. Remember the equation for acid balance: CO2 + H2O ⇌ H2CO3 ⇌ HCO3− + H+ If there is a low amount of CO2 outside, then greater CO2 than normal will diffuse out of the lungs. This will cause the blood to become more basic. To counteract the problem, a drug may be taken to both lower the blood pressure and help correct the pH. To do this, it blocks a symporter of HCO3- and Na+ in the proximal tubule of the kidney. Q: How would blocking transport of HCO3- help to lower the pH of the blood?arrow_forward
- When the production of acetyl-CoA exceeds the body’scapacity to oxidize it, acetoacetate, b-hydroxybutyrate, andacetone accumulate. When generated in large amounts, thesesubstances can exceed the blood’s buffering capacity. As theblood pH falls, the ability of red blood cells to carry oxygen isaffected. Subsequently, the brain can be starved for oxygen,and a fatal coma can result. Explain how severe dieting canproduce this condition.arrow_forwardConsider the cigarette smoke contain an average of 450 ppm carbon monoxide.

The "blowing off" of excessive carbon dioxide causes a decrease in blood H+ concentration. How can the carbonic acid buffering system function to correct this imbalance? CO2 + H2O → H2CO3 → H* + HCO3 O H2CO3 dissociates to form more H+ and raise pH. O HCO3- binds with H+ to form H2CO3 and raise pH. O H2CO3 dissociates to form more H+ and lower pH. O HCO3- binds with H+ to form H2CO3 and lower pH. O none of the abovearrow_forward
