Final answer:
The 3 H's in cardiopulmonary bypass (CPB) refer to Hypothermia, Hemodilution, and Hemolysis. CPB is a procedure used during cardiac surgeries, and these complications can occur during the process.
Step-by-step explanation:
The 3 H's are complications that can occur during cardiopulmonary bypass (CPB), which is a procedure used during certain types of cardiac surgeries. The 3 H's refer to Hypothermia, Hemodilution, and Hemolysis.
Hypothermia: CPB involves lowering the patient's body temperature to protect the organs during the surgery. However, hypothermia can lead to various complications such as arrhythmias and impaired blood clotting.
Hemodilution: During CPB, the patient's blood is diluted with a solution to prevent blood clotting. However, excessive hemodilution can result in anemia and decreased oxygen-carrying capacity of the blood.
Hemolysis: CPB can cause mechanical trauma to red blood cells, leading to their destruction and release of free hemoglobin into the bloodstream. This can result in anemia and potential kidney damage.
