- 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 calculationCalculate the enthalpy of vaporization at the normal boiling point (760 mmHg) of the liquid(water, boiling point of 100 celsius).Exposure 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.
- Calculate the pH of a blood plasma sample with a total CO2 concentration of 26.9 mM and bicarbonate concentration of 25.6 mM. Recall from page 67 that the relevant pK2 of carbonic acid is 6.1The equation describing the linear relationship between hemoglobin concentration and absorbance at 520 nm is y=0.0523x+0.011. If the absorbance value is 0.6, calculate the % hemoglobin in whole blood.What effect does hyperventilation have on blood pH and why? What simple measure can be used to correct the pH imbalance and how does it work? What effect would hyperventilation have on hemoglobin O2 saturation in a normal healthy individual? What effect would a PaO2 of 60 mmHg have on hemoglobin O2 saturation and why? (explain in terms of the O2-Hb dissociation curve)
- Determine and report the pressure of collected hydrogen gas in atmospheres. Report this result to one more digit than allowed by applying the rules of significant figures. (1 atm = 760 mm Hg, an exact conversion factor.) Determine the moles of hydrogen collected by substituting the appropriate quantities into the ideal gas equation and solving. Report this result to one more digit than allowed by applying the rules of significant figures. Notes: the gas temperature is the same as the listed temperature; R = 0.082057 L-atm/mol-K. Be mindful of units. Determine the experimental atomic mass of Cu. Round this result to the correct number of significant figures.
