Alright, so let's take a look at the bag valve mask a bit closer. Professional rescuers are encouraged to use the bag valve mask whenever possible but one important aspect of this is that it takes practice. It's not that it's rocket science at all, but it just takes practice to be able to get your fingers placed correctly and to get your own technique down with some of the hints I'm going to show you to be able to seal the mask to the face of the patient. Another mistake that's commonly made is we think
we're going to crush the mask down onto the face of the patient. When in reality, we're sealing it, but bringing the face of the patient up into the mask. Not mask down on patient's face. Face up into mask. That combined with sealing with the CE method allows us usually to get a pretty good seal. Some of the reasons you might not get a good seal
is deformity to the face, traumatic injury to the face, or a lot of facial hair. If that happens, you're going to do the best you can, but it's probably going to be an intubation patient at that point to be able to control the airway. But for this case, we're talking about basic life support with a bag valve mask. Notice, I've taken the reservoir bag off. There is no oxygen hooked up to this bag. If there were oxygen hooked up to this,
we would be at high flow oxygen delivery with bag expanded. The way you do that is cover the outlet while it's on high flow, the bag would expand and fill with air, and you're ready to start ventilating to capture as much of that percentage of oxygen as possible. But we're just going to do room air, which is perfectly acceptable as well. In fact, some statistics and studies are showing that it might be just great to do it with room air.
Remember, too, the bag valve mask is helping this person who might possibly be in cardiac arrest because we're not giving them any percentage of our carbon dioxide thereby contributing to their hypercarbia and the CO2 buildup in their body. So there is a benefit of that. The other benefit is we're not putting our face anywhere near the person's face. Therefore, protecting ourselves from infection as well.
So, when we put this on the patient's face, we're going to make sure that the narrow, pearshape of this mask is going on the bridge of the nose. Then, the wider or broader part of the mask is going to cover below the lips and above the chin. Then, coming in at the stem with our fingers, our C, our thumb and first finger, we're sealing in this case the left side of the mask
RGB104 Retro Gaming on CRTs and PVMs MY LIFE IN GAMING
If you've been playing games for any amount of time, then you most certainly have memories of playing games on your childhood CRT. Yet for all their history, in so short a time, CRTs have fallen into disuse. Large and bulky in comparison to the sleek and thin screens of today, most people think of CRTs as useless unwanted
spacewasters that you couldn't pay someone to take away. Throughout the RGB Master Class series, we've talked a lot about how our RGB journey began with researching tutorial scalers for playing retro consoles in high quality on modern HDTVs. But that's not the solution that everyone is looking for.
To get the best picture, sometimes you've gotta go backwards. Wait, so why would I want to deal with one of those big old TVsé Welcome to RGB 104. Let's take a look at gaming the old fashioned way. (Theme Music)
(static) (fanfare music) Cathode ray tubes drove television technology for over half a century. Giant glass bulbs in big bulky boxes. While nearly everyone has moved onto flat panel HDTVs at this point, CRTs are still coveted by retro gamers.
In fact, many would argue that CRTs are the absolute best way, some would go so far as to say the only way, to play retro tutorial games the way the developers intended. Whether you agree or disagree is up to you. Home console games designed for standard definition CRTs in North America
primarily use resolutions of 240p or 480i. That's progressive and interlaced, respectively. Just in case you don't know, the short explanation is that progressive resolutions display a full frame at once, while interlaced resolutions rapidly alternate lines of horizontal resolution as a way of showing more detailé
