Here's an interesting simple technology that might come handy to anesthesiologists and others who tend to do lots of central lines. Making sure that you are not in a carotid (or subclavian or femoral arteries, etc) is not always as simple as many think. Sure, you can do a blood color comparison. You can also connect a vertical column, and see how far the blood will rise. But why to do these maneuvers, if you can have something at the end of a finder needle that does not add steps to your procedure? Meet Mirador Biomedical of Seattle, Washington that has just received FDA's 510(k) clearance for its Compass Vascular Access pressure measurement device, as well as a similarly designed Compass Lumbar Puncture pressure monitor.
