00:0-1	get a welcome to Tech Math channel . We're going
00:02	to be having a look at this video is how
00:04	to work out dosages that it to be given over
00:08	a period of different times . Okay , So where
00:11	these dosages Uh , you know , so so you
00:14	were asked to give a person 1000 mill of a
00:17	medication per day . But this was happening over four
00:21	different periods , how much you would be giving and
00:23	how often you would be giving it . Or other
00:26	types of questions might ask . You say you wanted
00:28	to give you 2000 micrograms of a mitigation a day
00:34	, but it's occur every six hours . So how
00:36	much would be giving them each dose ? And also
00:39	how often these would be occurring . So I'll show
00:42	you how we work these out . So say ,
00:45	um , so there's a couple of different ways these
00:47	can be presented , but they're fairly simple to work
00:49	out once . You know how . So the example
00:52	I just said is say you were asked to give
00:54	a patient 1000 mil of a medication and this was
01:01	per day . Okay ? This is 1000 mil per
01:04	day and this was to happen for times . Okay
01:12	, So over four different dosages . Okay , so
01:16	four different times during the day , you were to
01:19	dish out this 1000 mil . So how first off
01:24	you might question , how much would you be giving
01:27	them each does so to do this , What we
01:29	do is we have a look at how much they
01:31	need And over how many doses there to have .
01:35	And we divide this sort of 1000 divided by four
01:42	means that there to have 250 mil each dose .
01:53	How often are they to have this medication ? Well
01:56	, we can then answer that because we can say
01:58	, well In a day there are 24 hours .
02:03	So we divide 24 up four times . This means
02:08	that 24 divided by four . This means it's six
02:11	. So it's there to have this medication every six
02:17	hours . Okay , that's the type of question you
02:21	were doing these . They're fairly simple and you just
02:23	have to think logically about them when you get them
02:26	. Okay . It's a fairly simple divide type question
02:30	. So I'll give you another example of this .
02:35	So say you were asked um to give a patient
02:44	350 milligrams and this was to happen , this is
02:51	per day again and this was to happen Over two
02:57	different doses . So two times . So to work
03:02	out how much I'd get , each dose is fairly
03:05	simple . We'd go 350 divided by two is equal
03:13	to They'd get 175 mg each dose . How often
03:22	Again we would get the 24 hours in a day
03:27	and we were divided This into two or 2 into
03:30	this . So it means that they get it every
03:34	12 hours . So do you see how that works
03:37	? It's a fairly simple calculation . Again , just
03:40	think about it logically when you do this . Now
03:44	, the other type of question that you might get
03:46	with these is as follows As you might get given
03:51	this type of information you might get given that the
03:54	patient needs 3000 only go micrograms and this is what
04:02	they're supposed to get per day and this is to
04:08	happen every six hours . Yeah , this type of
04:16	calculation is slightly different . First off , you've been
04:19	told that second piece of information so you don't need
04:21	to work that out . You don't need to work
04:23	that , it's every six hours , but you do
04:25	need to reverse . You need you need you need
04:29	to do something to work out your how much dosage
04:32	each time . And this is very , very careful
04:33	when you be very careful when you do this .
04:35	It's not just a simple matter of now , I'm
04:37	just going six into 3000 . If you do this
04:40	, you get the wrong answer . In fact every
04:43	six hours means we could work out how many dosages
04:46	they're actually going to get . So Here we go
04:49	, 24 divided by six . It will mean that
04:53	they're going to get four doses . You see that
05:01	24 divided by six means of getting four doses .
05:04	So now we're going to use this bit of information
05:07	to work out this next part . So How much
05:11	do they get each dose of getting four doses ?
05:13	3000 divided by four . And this means that they
05:19	are getting how much It's going to be 750 micrograms
05:32	each dose . So do you see how we work
05:36	that out first ? We have to work out how
05:39	many doses they were going to actually get and it's
05:42	a slight variance on it's a little trick just to
05:45	be wary of when you do these . So I'll
05:47	give you one more example of this to say the
05:52	patient was to have um 720 mark programs per day
06:05	and this was to happen every eight hours . Okay
06:15	, so what do we do we have to first
06:17	work out how many doses they're actually going to get
06:20	? Okay ? We want , how many doses are
06:22	going to get then we can work out how much
06:24	each dose will actually be . So How many doses
06:27	are going to get ? It's happening every eight hours
06:29	. So 24 divided by eight means that they're going
06:32	to get three doses of this or three different times
06:39	, we're giving them the medication . So how much
06:43	are they getting each dose ? They're going to get
06:45	720 divided by three , 720 divided by three .
06:52	They're going to get 240 Michael grabs each dose ,
07:04	so hopefully you're okay with working things out . Ah
07:08	They're not too bad , but you have to be
07:10	fairly systematic about how you do them and think fairly
07:13	logically . Okay , that's probably the first thing that
07:16	you will be wanting to know is put your information
07:18	out in this particular order , then you want to
07:21	know how many doses you're getting okay . If that's
07:25	not already given , you can then work out how
07:28	much they're getting each dose and if it's not already
07:31	given how often this dosage is happening and that would
07:35	be how you would do this . Okay . Anyway
07:38	, hopefully that video is of some help see you
07:41	next time . Bye .
