What is C O P D treatment. Investigation and treatment

What other than make cram like sure we talk about them to see me today.

Otherwise known as C. O. P. D.

Try these diseases have abbreviations in medicine this one is chronic obstructive pulmonary disease so what is C. O.P. D it's a common preventable and treatable lung disease and to draw some terms.

But you'll see in patients with emphysema or C O P D is shortness of breath. And you'll also see off.

And if it's what you missed well. So, these are very nonspecific symptoms but they're very typical of what you see you’re PT.

So how important of a disease. Is this a couple of statistics no it's the third. Most common cause of death in the U. S. Trial be significant so there's a.

Number two and is a number one above it and that's a heart disease and cancer.

And sometimes these are depending on how your survey will flip spot trials also number four and number five the key here is that this is the only cause of death in the United States out of these five that actually gone up for about two thousand seven two thousand and ten all the others have gone down while.

In frequency except for this one so this is a pretty significant disease that we've gotta be concerned about.

In addition to all of this it's also the seconds leading because of disability well.

Okay so the bottom line here is that this is a very important disease to know about and in case.

You're wondering how much this costs the US healthcare system in United States every year the answer is about fifty is with a billion.

Okay fifty billion with a B. a lot of money so as I mentioned C. O. P. D.

Or emphysema is a disease that affects the lungs. And specifically if you were to take a look at your lines of course know that your lungs have two sides.

The major airway call the trachea and it branches off into the right and left main stem Broncos and from there it just goes down to smaller and smaller branches without getting into too much trial well if we were to take these very small bronchi oles or respiratory bronchi oles they would eventually ends in triremes like cluster called in Aeolus. And this is actually increases the surface area.

So this is what a normal respiratory bronchial would look trial and. If you were to take the all these ally in the entire lawn and spread it out it would be about the size of a tennis court trial pretty big. Bronchi oles of course allow the air.

That you breathe then to go down and because gas exchange.

No C.O.P.D affects Daren areas it affects this bronchus the small brush hill and it also affects the Aeolus in a bad way trial.

What happens is because the elastic fibres are destroyed we'll get to that later is that that airway becomes free collapsible and essentially it becomes very small and that's where the obstructions UP comes from.

Furthermore you also get a get destruction of the of the L. the Ola. And you lose a lot of surface area. So, instead of having a nice time.

For it you end up with maybe a badminton court or even a table tennis court here that you're that you're working with so this service becomes much smaller.

In all these changes happen throughout the long but mostly in the upper right along. And as a result of that it's hard to get the air out there's an obstruction. And so that's the key point there is dial. Air cannot get out of the lot that's why it's called chronic obstructive pulmonary disease.

Because these Ala you'll like all our old destroyed and become areas of large balloons if you will. The long actually Reese’s insights and as a result of that you get these patients with large lawns. But there are full. Airing and they can't get the air out and that's basically C. O. P. D.

So the way that we diagnosed C.O. P. D is based on this.

So we sitting down in front of us parameter and that's basically machine you breathe into it and how much you breathe out. And we ask them to basically. Breathe out after taking a deep breath then. That is as much air as they possibly can and we put.

So this is represents how much air they can blow out given enough time to blow it out so we given ten seconds to blow it out enough time that they need to blow everything they possibly can out.

And we call that by the way the forced Vital Capacity.

Otherwise known as the F. B. C. so that's how much air they can blow it completely well.

We said that C.O.P. D isn't obstructive lung disease and so what we're really looking for is how fast right.

In that area because if there's an obstruction that's good it in he'd their ability get that error out as fast as they possibly can and so the next thing that we do is we have them do the same in over but we measure how much comes out.

One seconds, So there's kind of a time and proportion to this.

How much can you blow out given an infinite amount of time and how much can blow out.

In just one second. So there's a little bit of a velocity factor involved there and so what we do is call that by the way the force. Exit the Tory. In one second this is otherwise known as the F. T. V. One Trial. Okay so then we do a very simple calculation we measure. And we see.

We take this number. Force expert twenty volume. And we. Had him by the force vital capacity number and come up with a fraction. This is known as the F. E. V. one divided by the F. B. C. Rattle. Okay and The definition that's come up in the literature is at that point seven Zero.Eight seven zero is the cut off yes. The one provided by the F. E. C ratio is less than point seven zero that means that you could get less than seventy percent of the air the you can normally get out get an incident at a time out in the first set. That means you've got obstructive lung disease.

More than points that out that means you don't have a tropical disease.

Hello The question here is. Can out. At least set the balanced in per second and if the answer is yes you don't have a truck the one dies.

No and it's less than point seven then you have obstructive lung disease. And of course the lower this number is.

The F. T. V one worship C. O.P. D is going to be. Okay so let's. C. O.P. D one Common. It costs a lot Number two It's the third Leading cause of death and it's only one of the five that are asked repeating in frequency. Number three Causes difficulty with breathing out right on the main number for you to do this is the cross sectional surface area causes drops in oxygen.

You diagnose it by spy ROM the tree. And then finally over to six the diagnosis is the F. T. V. one line and thought of by the F. T. C. is less than seven.
