Respiratory variation in peripheral arterial blood flow peak velocity to predict fluid responsiveness in mechanically ventilated patients: A systematic review and meta-analysis

tailieu.vn

The fundamental cause of respiratory variation in per- ipheral arterial blood flow peak velocity was the respira- tory variation of stroke volume. From the results of the study, the △ Vpeak of carotid artery had more value than brachial artery in predicting fluid responsiveness. The reason may be that carotid artery had the advantage of anatomical location (closer to the heart). Thus, the blood flow of carotid artery is more sensitive to the change of stroke volume than brachial artery.
