stroke volume variability

Abbreviation: SVV
The change in the amount of blood ejected from the left ventricle into the aorta with each heartbeat. Stroke volume variability measurements may be used to assess the autonomic responsiveness or preload of critically ill patients during positive pressure ventilation. If SVV is > 15% during a positive pressure breath the patient is volume depleted.

Intrathoracic pressure has been known to increase in patients with raised intra-abdominal pressure and the Trendelenburg position (10) Accordingly, the usefulness of PPV and SVV, which are affected by changes in intrathoracic pressure, in predicting fluid responsiveness during laparoscopic surgery under these conditions may be questioned.
In one report, static SVV was abnormal in only 11 percent of subjects [27], while in another study, SVV was abnormal in nearly all subjects (96%) [26].
