Does 7% Saline cause Blood Pressure to go up?

@healthybon Bon - This topic has come up before. Here is the math:
The recommended daily allowance (RDA) for sodium is 2300 milligrams. A 4ml vial of 7% saline solution contains 280 milligrams of sodium (4ml/neb is the recommended amount. If your vials are larger, you should use 4ml and discard the rest.) So if you nebulize 1 vial per day, you get 280 mg of sodium or 12% of your RDA, 2 vials would be 24%.

Here is the computation: to make 1 liter of 7% saline, add 70 grams of salt to 1 liter of water. So, 1 ml of water contains .07 grams of salt (70/1000) or 70 milligrams. A 4ml vial contains 280 milligrams (4X70).

If you feel the benefits of the saline are important, and blood pressure is a concern, you can work to reduce the amount of sodium in the rest of your diet to compensate.

I'm wondering if digesting salt and having salt absorbed into the body through the lungs would have different absorption rates. Ever since I've started with the nebulizer with 7% saline, my skin tingles, burns and itches. I feel these sensations intensify while I'm on the nebulizer. I've heard that the body can have an auto immune response with too much salt intake which can cause a rash and itching. My medical team doesn't think so, but I'm not imagining my symptoms. I never had a problem with salt intake before.

I'm also nebulizing with the 7% saline. My resting heart rate has gone up, and so has my blood pressure. Of course, I'm not sure it's an effect of the saline. I recently had an EKG that showed no problems, so my doctor doesn't seem to be concerned. But having a resting heart rate of 90 - 100 must not be good.

Inflammation can cause a rise in heart rate. When I am sick my heart rate and blood pressure are more elevated than normal. If you wear a HR tracker you can see this correlation easily. Heart Rate (HR) can go 10 points higher when you are sick.
