(G) Describe the general design of the membrane oxygenators used in these procedures. What important characteristics of the alveoli does this design mimic? How efficient is the transfer of oxygen into the blood?
1. (G) Other than those mentioned in the text, list two important properties for the materials used in the pumps and two important properties for materials used in the membrane oxygenator. Explain. Would metals or polymeric materials (plastics) be more appropriate for these two applications?
2. (G) What are three safety concerns for the heart–lung bypass device that have not been previously discussed?
