Mr. Malone is going into a shock because of blood loss, so paramedics infuse a saline solution. Why would this help?
fredd [130]
Saline solutions have the same or close to the same amount of salt as our blood does, so we get the amount of salt needed for our bodies. During blood loss, you lose the salt you need, so they're basically adding it back in with the saline solution, making your electrolyte balance go back to normal level. It also gives us the right amount of water to keep us hydrated.
