As another way to estimate this, here’s a data sheet for some microbubbles: https://pdf.benchchem.com/1673/Application_Notes_and_Protoco... So 1-5e8 bubbles per mL, and let’s suppose you inject 5mL. (I have no idea what the human dose is, but that’s what’s in this particular kit.) You apparently have 5e9 or so RBCs per mL of blood: https://en.wikipedia.org/wiki/Complete_blood_count You have about 5L of blood, so that’s three orders of magnitude more volume than the contrast, and RBCs are 10x-50x as concentrated as the microbubbles in the syringe, so about 4 orders of magnitude concentration difference. It’s basically changing this from a 0D problem to a 1D problem. |
