31. In a healthy patient, his or her cardiovascular system always increases blood flow in response to increased oxygen demand . 32. Thus the hypertrophic heart, which has a greater oxygen demand , may have a compromised supply of oxygen and nutrients. 33. Tachycardia in the presence of AMI can reduce coronary blood flow and increase myocardial oxygen demand , aggravating the situation. 34. Therefore, it think that the increased oxygen demand will be redly met by the volume of water in movement. 35. It is not useful in ischemic heart disease because it increases heart rate and thus increases myocardial oxygen demand . 36. This is measured by the levels of biochemical oxygen demand ( BOD ) and chemical oxygen demand ( COD ). 37. Resuspending nutrient solids like these can introduce oxygen demand into the water column, and result in oxygen deficient dead zones. 38. This is measured by the levels of biochemical oxygen demand ( BOD ) and chemical oxygen demand ( COD ). 39. ACE inhibitors relax blood vessels, and decrease blood volume, which lowers blood pressure and decreases oxygen demand from the heart. 40. Foam separation has also been found to decrease the chemical oxygen demand when used as secondary treatment technique for wastewater.
