It is measurement on an ordinal scale. Level 1 is less than level 2 which is less than level 3 and so on. But the difference between levels 1 and 2 is not related to the difference between levels 2 and 3, etc.

Low back pain
. I found a great video on how to use the Hi-Dow units at Pain-Less.com
I don't know about others but I had several blood clots that were the size of my entire hand. At one point as I was getting up out of the bathtub, I pushed my arms down on the sides of the tub for leverage and felt like I passed my liver! Talk about shocking! I thought to myself at one point "can one lose this much blood without dying?". The hospital I went to said "Just ride it out until the end. If you faint come back but otherwise you're fine". I have always been one to not want to bother people. I felt like I was annoying the staff at the hospital so I didn't ask the questions or get all the info I needed. Don't do the same! Ask a million questions, take as much time as you need, and don't let hospital staff brush you off. They are supposed to be here to help and educate us so don't be afraid to ask them to do their job. Anyone going through a miscarriage, unfortunately lots of women understand your pain. Reach out and talk to a group of women going through the same thing. Best of luck and don't give up. Lots of women who have one or more miscarriages can go on to have many healthy babies.
DefinitionA reticulocyte count measures the percentage of reticulocytes (slightly immature red blood cells) in the blood.How the test is performedBlood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.The blood sample is sent to a laboratory. A special stain is used to identify the reticulocytes.How to prepare for the testNo special preparation is necessary.How the test will feelWhen the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedThe test is done to determine if red blood cells are being created in the bone marrow at an appropriate rate. The number of reticulocytes in the blood is a sign of how quickly they are being produced and released by the bone marrow.Normal ValuesThe normal range depends on the level of hemoglobin, and the range is higher if there is low hemoglobin due to bleeding or red cell destruction.What abnormal results meanA higher-than-normal percentage of reticulocytes may indicate:BleedingErythroblastosis fetalisHemolytic anemiaKidney diseasewith increased erythropoietinproductionA lower-than-normal percentage of reticulocytes may indicate:Bone marrow failure (for example, from drug toxicity, tumor, or infection)Cirrhosis of the liverFolate deficiencyIron deficiencyKidney disease with decreased erythropoietin productionRadiation therapyVitamin B-12deficiencyAdditional conditions under which the test may be performed:Anemia of chronic diseaseCongenital spherocytic anemiaDrug-induced immune hemolytic anemiaHemolytic anemia due to G6PD deficiencyIdiopathic aplastic anemiaIdiopathic autoimmune hemolytic anemiaImmune hemolytic anemiaPernicious anemiaSecondary aplastic anemiaWhat the risks areThere is very little risk involved with having your blood taken. Veins and arteries vary in size from one patient to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.Other risks associated with having blood drawn are slight but may include:Excessive bleedingFainting or feeling light-headedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)Special considerationsThe reticulocyte count may be increased during pregnancy.ReferencesZuckerman K.

The Pain Scale in the US is a simple self-measurement "from 0 to 10" on which a patient ranks the pain they feel "in this moment".
AVPU scale stands for alert, verbal, pain, unresponsive
This is a fake unit of measurement made popular by an internet rumor. A scale of pain measured in dols (1-10) is used sometimes, but is relative and the validity of it is questionable at best.
I've included a couple of links which should explain better the differences among the four levels of measurement: Nominal, Ordinal, Interval and Ratio. The nominal level can be thought of as the "name" level. I'll give you an example of nominal level of measurement. Perhaps you are collecting data on the types of cars that go through an intersection. You classify the vehicles passing by as trucks, cars and motorcycles and count how many of each pass by. Ordinal is the "order" level, where some natural order of data is possible. The difference between measurements has no physical meaning. An example of ordinal level of measurement. A hospital asks in the emergency room, for patients to describe their pain on a level of 1 to 10, which 10 being the most severe. As given in the first link, it is interesting that there is not complete agreement on this system of classification.
Ask the patient to point to a pain chart to indicate his level if pain on a scale of 1 to 10.
One of the first things to do in case of a sports injury is to determine the pain level. Ask the athlete the level of pain on a scale of one to ten with ten being the worst.
A numeric scale is appropriate because the patient/client can indicate, by pointing or raising fingers, to indicate his/her current pain level. Clients with motor aphasia cannot express themselves verbally or in writing.
Alert Verbal Pain Unresponsive
Del units is a ficticial unit for pain measurement. There's no way to mesure pain in a objective way because there are just too many factors to take into account. The most common way used is a scale in which the patient (or the person of the study) evaluetes from 1-10 its pain.
That's always a tough one, since everyone is different. My pain scale is likely a lot different than yours, and vice-versa. I've lived with high levels of pain for so many years that most of what I feel normally would likely be at least uncomfortable for most people, excruciating for others. The easiest way is to chart it on scale, and I've added some links below to help you out. Figure that on the scale, Zero is no pain, and Ten is you're either climbing the walls in so much pain that you can't function or move, or you're screaming your head off. Of course not everyone reacts the same way to higher levels of pain. The key I use for a 10 is when a I get pain that's strong enough that it leaves me barely functional, e.g., unable to walk normally, move, eat, breathe, etc. Pain tolerance also increases as you experience higher levels of pain for longer periods, so the scale is relative to your own pain tolerance level. As I said, what's excruciating for some people is just an irritant to me or others. What you need to do is to think of the worst pain you've ever experienced, and note that as your "10" for the pain scale. Any other pain you experience, rate it against that. If you've never had any major injuries or pain, you're lucky, but everyone has some level of pain that they've experienced. Again, use your highest level of pain that you've experienced as your personal "10" for the scale, and adjust anything else accordingly. Later down the road you'll likely experience something worse, and that becomes your new standard for the upper pain scale, and everything else should be judged against that.
Speaking of a scale of 1-10, if your arm comes off, the pain will be at a level 10. You will cry because it's the world's worst pain. Then soon, you'd pass away and will never be seen again.
