| 41. | The most common causes of hypoxemia are ventilation-perfusion mismatch, hypoventilation, and shunts.
|
| 42. | It may be that increased perfusion to the brain and other organs also have indirect benefits.
|
| 43. | In effect, the two arteries do not function as collateral perfusion to the watershed area.
|
| 44. | Arterial hypoxemia in these patients has been attributed to ventilation-perfusion inequality and intrapulmonary shunting.
|
| 45. | For example, rubidium chloride is used in isotopic labeling to evaluate perfusion of heart muscle.
|
| 46. | Using radioactive microspheres is an older method of measuring perfusion than the more recent imaging techniques.
|
| 47. | Greater discussion on the effect of blood perfusion on heat transfer is given in Section 2.
|
| 48. | For perfusion experiments, an electrically powered roller pump was first used by Fleisch in 1935.
|
| 49. | However, this may actually be advantageous for applications such as tumor perfusion and angiogenesis imaging.
|
| 50. | The remaining channels are opened and constant perfusion and superfusion are adjusted using separate syringe pumps.
