Whoops!! I hit enter too soon.
Anyway, an example, probably not a good one, because there is no outcome to report.
A woman into ED with PV bleed, slight at the start, but became much heavier, she was 10/40. BP was stable for around an hour, then dropped quickly, tachy, pale, sweaty, and c/o nausea and dizziness. PV bleed increased. Despite positioning, IVF STAT, BP continued to drop, and bleed increased. Result was an emergency I&D to remove retained products. Is this what you are looking for Bronwyn?

Yes this is good Debbie. the signs you saw were related to her haemorrhage and drop in blood volume which caused the BP to drop.


Now we need to think about the homeostatic mechanisms related to maintaining BP.. was the tachycardia a compensatory mechanism? why the faintness & pallor, sweatiness.


which part of the nervous system is activated?

You may need to go to your cardiovascular chapter in the textbook to get more detail about control of BP....


Did they put up IV fluids?
