In this article, we’re gonna talk about how a cpap machine really works in the CHF patients. What’s really going on? Because there are some misconceptions out there. Now, to help illustrate this, I’m gonna use a syringe as an example here.
First, we have to talk about how people breathe. And let’s identify some of the parts of the syringe as they apply to our anatomy for this illustration. So the hole up here at the Top of the syringe is the hole in the middle of your face that your airway. This would be your lungs right here, and the plunger portion would be your diaphragm. Now, when people breathe, take care in and out of the body, it’s mostly through contractor of the diaphragm. The diaphragm drops down. Like a vacuum, you suck under negative pressure. We breathe in under negative pressure.
Now, let’s think about this for a moment. When that plunger falls down, which way the sides of the syringe up here want to go up in the chest? Which way do they want to move? They want to move inward, right? But pull the surrender down tight, this wants to move inward. That’s exactly what happens in the human body. When that happens, it compresses the low pressure, vena cava. Every time you inhale, you’re compressing that vena cava and you’re helping supplies some pre load, some blood return to the heart. It’s exactly what happens. In fact we call that the respiratory pump. So every time the diaphragm drops down, it squeezes in a little bit compresses the vena cava and helps to return blood to the heart. Cool.
Now let’s say, for example, instead of the diaphragm working, we just blasted air into the top of this hole and we push the diaphragm down. Which way would the sides go then? They would go outward,not compressing on the vena cava. So for just blasting into somebody sides wanna go out, we’re not compressing the vena cava, so we lose that amount of pre load. We’ve lost our respiratory pump.
But when would we ever just blast daring to somebody ridiculous like that? Doesn’t make any sense that would never happen. What positive pressure ventilation reduces the respiratory pump, reduces pre load and drops your blood pressure. It’s exactly what happens every time you’re bagging somebody. I wish there was a way we could help return some of that negative pressure and utilize the respiratory pump. This is the rescue pod. That’s exactly what this device does. It helps to return some of that negative pressure. So we can utilize the respiratory pump helps to compress the vena cava,helps to improve pre load.
Ok,Let’s think about another scenario. Let’s say that when the diaphragm drops down and creates that negative pressure, at the same time, we put air into the patient under positive pressure to negate that to equal that pressure, so that the sides aren’t coming in. It’s not compressing the vena cava and we’re reducing pre load to the heart. That’s what cpap does. That’s exactly the mechanism we’re looking for in c pap to negate that negative pressure. Take the pressure off the vena cava, wipe out the respiratory pump, and reduce pre load to the heart during chf so the heart can play catch up a little bit.
Now, when it comes to compliance with cpap machines, it’s not usually the inspiratory phases bug in the patient. It’s the exhalation when they’re exhaling. Think about it, c pap machine, continuous positive airway pressure. Let’s say we put it at 10 centimeters of water pressure, right? So when the patient in hails, they’re negating that pressure. They get all that pressure coming in. Feels great. The problem is they can’t exhale against it. So I have a tip in the field for patient compliance. If your patient is able to do this, because what’s more beneficial the inspiratory phase, or when they’re exhaling, the inspiratory phase, we’re trying to wipe out that pump. Right? Here’s what you do. If the patients able give them the mass, give them control the mass, have them hold the mask on the face, and you get a good seal during the inspiratory phase. But if they’re having trouble exhaling around that pressure, have them cracked the mask a little bit? So they’re allowed to exhale. That’s what it is. They just can’t exhale very uncomfortable. It’s hard to breathe against 10 centimeters of water pressure. Try that. And then as they get used to it, you’ll get better compliance.
Now, how do you know what’s working? The respiratory rate starts to come down, sets improve, entitle improves. If you have title on at the same time which you should, so the patient gets better. Another technique, I always follow your local protocol, but maybe start the c pap at a lower level and gradually rise it up. So we can get compliance as opposed to strapping this thing on this patient’s head and and watching him wrestle with. I wish there was a way that we could have a lot of pressure on the way in, but less pressure on the way out. So the patchy can exhale and feel more comfortable. We do that’s called bipap machine and we use that in the hospital by level ventilation. So they get more pressure on the way in to wipe out that pump, reduce pre load to the heart. When the patient exhale, the machine automatically lessens the pressure.
So it’s easier for the patient to exhale and you get better patient compliance. This has been just a quick review of how cpap really works. Buy the top rated cpap or bipap machine for CHF, sleep apnea at RESJOY.
