So all in all, although math can be a pain sometimes, it does serve a purpose in most circumstances. If math wasn't involved in healthcare I'm afraid to see what our healthcare system would look like.

What do all these different medications do?

# data[].attributes.body
Different medications have different purposes. However they also have side affects. You know, that long list of things that could go bad if you take this medication that's said really fast at the end of commercials for different medications. For example there are: Benzos, Beta Blockers, Dopamine, and Cholinergics, just to name a few. The link bellow has a list of drugs and all of their uses.

Just like how we have to convert Ounces to Pounds or Inches to Feet; doctors, nurses, and paramedics have to do math and conversions for administering medications.
Formulas - How doctors and nurses have to convert the orders to give the proper amount of medication.
Translating - Doctors and nurses have to translate the volume, time, drop rate, and flow rate to make sure the patient is getting the proper amount of medication.

The first successful usage of IV saline was performed by Dr. Thomas Latta of Leith, in Edinburgh, year 1832.

How Doctors Convert Down to Milligrams to Prescribe Medication to Their Patient.

# data[].attributes.body
Doctors regularly write prescriptions to their patients. Doctors must indicate the specific medication and dosage. They must calculate between the patients age and body mass to figure what dosage is the correct amount for that patient. As you can see, if doctors only know the weight in pounds they must convert that measurement into kilograms, then find the right about of milligrams for the prescription.

Why Doctors and Nurses Have to Know What they Are Doing.

When instructed by the doctor, nurses routinely use addition, fractions, ratios, and algebraic equations, each workday to deliver the correct amount of medication. They must also monitor any changes that may affect the patient and report that information back to the doctor.

Doc orders NS1000cc over 3 hours (15gtts/cc)
How many cc/min will the patient receive?
How many gtts/min will the patient receive?

# data[].attributes.body
NS1000cc over 2 hrs (15gtts/cc)

First you must convert 2 hours into minutes = 120 minutes. So it becomes 1000cc divided by 120 which gives us 8.33 cc/min. We then take 8.33 and multiply it by 15gtts since that's our given drop rate. Which gives us 124.95. We then round that and get 125 gtts/min.

Simple right?

Volume (cc) divided by Time (hr/min) Multiplied by Drop Rate (gtts/cc)
Equals Flow Rate (gtts/min).

Determining how much medicine to give a patient can be very confusing to someone that's never done it before. Throwing you into it right away is mean, so I wont do that. What I will do is show you how to calculate the flow rate for administering normal saline. Or "fluids" as I'm sure many of you have heard them referred as, if you've ever watched a medical show. But before I do, I'll give you some background on medical terminology.

# data[].attributes.body
Depending on why you're in the hospital, you'll be given different medications that will hopefully help you. But how do the doctors know how much to give?

Good question, the needle is not our focus, other than there's different sizes. It's what the catheter provides that pertains to math. And that's medication.

# data[].attributes.body
Syringes are used for a single dose and are thrown away (in a specified container). IV catheters are used as ports into your body that the doctors, (or paramedics, if you're picked up by an ambulance,) can administer for any needed medications you might need without having to poke you multiple times. They are inserted directly into a vein in either your arm, hand, or even your leg, and neck, if needed. There's a clear sheath over the needle, that's the part that actually stays inside when the needle is pulled out. Then the doctor or medic will connect what is called a "lock" to the "port" (the pink, blue, green, and yellow, cap you see in the picture above) which allows the fluids to enter your body.

# data[].attributes.body
Yes, yes I know, everyone hates needles.

Behold! The IV (intravenous catheter).

Well...sometimes, that is a syringe that is used for a one time dose.

If you're in the hospital, chances are you are sick or hurt, and you will need medicine to help you feel better. But how are those medications given?

What Are Some of The Ways Math is Used in Healthcare? 

# data[].attributes.body
If you think about it, healthcare providers use math in pretty much everything they do. Whether it's counting the number of patients they treat, how much of a medication they have in stock, beds available, or the number of newborns in one day. These are all just examples of how it's used, but we want to talk to you about one in particular.

# data[].attributes.body
In the healthcare setting, math is used every minute of every day. Along with science, skill, biology, physiology, etc. Needless to say there's more to healthcare than just medicine and surgery.
