Unscramble the Blue Letters

Let me show you a little bit about how this machine works. Voila! Here she is. When you have electricity, everything in this machine begins in the base. There's a built-in oxygen concentrator down there. Now you've heard me mienton oxygen a few times at this point. Essentially, to dleiver anesthesia, you want as pure oxygen as possible, because eventually you're going to ditlue it, etiasnlelsy, with the gas. And the mixture that the paneitt inhales needs to be at least a certain percentage oxygen or else it can become droangues. But so in here when there's eirclticety, the oxygen concentrator takes in room air. Now we know room air is gloriously free, it is audabnnt, and it's already 21 percent oxygen. So all this concentrator does is take that room air in, filter it and send 95 percent pure oxygen up and across here, where it mixes with the anesthetic agent.

Original Text

Let me show you a little bit about how this machine works. Voila! Here she is. When you have electricity, everything in this machine begins in the base. There's a built-in oxygen concentrator down there. Now you've heard me mention oxygen a few times at this point. Essentially, to deliver anesthesia, you want as pure oxygen as possible, because eventually you're going to dilute it, essentially, with the gas. And the mixture that the patient inhales needs to be at least a certain percentage oxygen or else it can become dangerous. But so in here when there's electricity, the oxygen concentrator takes in room air. Now we know room air is gloriously free, it is abundant, and it's already 21 percent oxygen. So all this concentrator does is take that room air in, filter it and send 95 percent pure oxygen up and across here, where it mixes with the anesthetic agent.
