The correct conversion factor for solving the problem “
Concept Introduction:
Measurement is the measure of quantity, capacity, dimensions or extent of something. Mass, length, pressure, temperature, volume, time and concentration are some common type of measurements. English system and metric system are two types of measurement systems that are in use in the United States. Measurement wise both English system and metric system are precise. There are instance where measurements from one system has to be changed to their equivalent in other system. This is called the conversion factor. These conversion factors always appear as pairs.

Which of the following best summarizes the recommendations on how to address this concern? A. Never administer supplemental oxygen to patients with COPD as the risk of them stopping breathing is too great B. Treat acute hypoxemia with oxygen, but wean the oxygen as soon as possible C.

- The solubility of CO2 in blood is about 0.062 mL dL-1 mmHg-1. Arterial blood has a Pa_CO2 = 40 mm Hg and venous blood has PV_CO2 = 46 mm Hg, and cardiac output is 5 L min-1. A. Calculate the content of dissolved CO2 (in mL dL-1) in arterial and venous blood and how much CO2 is removed from the tissues and delivered to the lungs per minute. (Hint: CO2 content = solubility of CO2 * PCO2) (Hint: Rate of CO2 transport = cardiac output * (arterial CO2 content – venous CO2 content) B. If the volume diffusion rate of CO2 = 200 mL min-1 in the lung, what fraction of the total CO2 removal is accomplished through carrying dissolved CO2? C.
