Frequently negative IVC pressure is indicative of IVC collapse. Follow steps described above and continue to observe IVC pressure.
Add replacement volume
Add replacement volume
If reservoir volume has stabilised and drainage is effective, add more volume (no more than 300ml) to replace volume contained within liver. We recommend adding additional colloid unless you have reason to believe the haemoglobin is low.
