While going through the values of Vigilance/EDV it was found that the values in the database are suspiciously high. I have noted down a few of the case ids with the initial EDV values.
| Case id | Vigilance/EDV |
| 12 | 323 |
| 251 | 228 |
| 349 | 212 |
| 397 | 228 |
| 553 | 198 |
| 5693 | 290 |
| 5698 | 246 |
| 5837 | 177 |
| 6227 | 149 |
| 6297 | 295 |
I assume EDV is end-diastolic volume. Please note that EDV is normally <150ml.

Our dataset comes from real surgical patients, so it is subject to real world noise. When you see outliers in your data, you need to look at the relationship between the values before and after to determine whether they are real or noise, and you will probably need the help of an anesthetist. If you suspect it is noise, you will need to use various preprocessing methods to remove it.
