Sure. Sure. You are right. Blood management has become a focus for many hospitals as they're recognizing that it's not only one of the top 5 expenses of hospital for buying and providing blood to patients but also blood transfusion has, at least, there's been a correlation to suggest that blood transfusion can reduce -- well, increase mortality and increase morbidity. And therefore, there's a lot of attention of what to do to minimize blood transfusion. Having that study showing that it's all over the place, not only at different institutions, but even in a given hospital that -- and the tendency is to give more than is needed, but of course, sometimes giving it later than it's needed. So having a device that's a continuous way of measuring hemoglobin, that's an indicator of when you need blood transfusion, and 2 randomized controlled trials now showing that, in fact, it does reduce blood transfusion by 90% from the Mass General study in orthopedic patients, which are less bloody of procedures, and by 50%, in the neuro patients from Cairo University study, which is a high blood loss situation, we feel that we have something great to offer for patient care and for reducing cost. So to go back to your question of are we seeing momentum build? The answer is, yes. For example, just this last quarter, UCLA became one of the new better care customers where they're taking advantage of our guarantee, the blood transfusion related cost reduction guarantee, and 2 other hospitals have already begun that guarantee. They're about 7 to 9 weeks into it, and -- but as you know, we don't recognize the revenue from those sales until the guarantee period is over so that we don't get into a situation where, God forbid, we have to back something out. So we're confident that we're on the right track. We're confident that hemoglobin -- noninvasive hemoglobin is a lifesaver and a cost reducer. And I think, the feedback I'm getting from the sales leadership that momentum is building.
