One unit of blood is equal to 1 pint of blood.

One unit of blood can also equal 500 ml of blood.

Often, one unit of blood is enough.

Many patients with levels above 70 or 80 g/L may not need a blood transfusion.

One unit of blood is usually as good as two, and it may even be safer.

The blood type that lives the longest is Type O blood.

Chances are higher you'll live longer if you have type O blood.

Experts think your lowered risk of disease in your heart and blood vessels (cardiovascular disease) may be one reason for this.

The blood type that is the smartest is type AB.

People with (AB) blood type are the highest ones in the percentage of their intelligence.

And that scientists and geniuses in this blood group are more than any other holders of other blood groups.

The purest blood type is type O.

Type O blood types are the purest, especially O negatives, the universal donors.

The Type O's have the purest blood, or what Europeans used to call “royal blood”.

Because of their purity, they are the most environmentally intolerant and sensitive.

The rarest blood type is Type AB.

In the U.S., the blood type AB, Rh negative is considered the rarest, while O positive is most common.

Power red is needed more than blood in most places.

Although both blood and power red cells are needed so it's good to give either one that you choose but in some places power red cells are needed more.

In order to give or donate double red cells you must weigh between 130 lbs to 150 lbs.

In general, women and nonbinary individuals must be at least 5′ 5″ tall and weigh at least 150 pounds, and men must be at least 5′ 1″ tall and weigh at least 130 pounds.

When donating or giving double red blood cells you you can give the double red blood cells every 168 days.

A red cell donation is typically transfused within days, so the need for this component is ongoing.

You may donate double red cells about once every 168 days (24 weeks).

During this time, you cannot make other types of blood donations.

You have to wait at least 56 days or 8 weeks between the time of giving blood.

You must wait at least eight weeks (56 days) between donations of whole blood and 16 weeks (112 days) between Power Red donations.

Whole blood donors can donate up to 6 times a year.

Platelet apheresis donors may give every 7 days up to 24 times per year.

While both double red cells and whole blood are needed it's better to donate whole blood.

The order of draw is a process of drawing blood to prevent cross contamination.

The "Order of Draw" is designed to eliminate the possibility of cross contamination that may result in erroneous results.

It is based on CLSI Procedures for Collection of Diagnostic Blood Specimens by Venipuncture; Approved Standard Sixth Edition, October 2007.

The recommended order of draw for plastic collection tubes is: First - blood culture bottle or tube (yellow or yellow-black top) Second - coagulation tube (light blue top).

If just a routine coagulation assay is the only test ordered, then a single light blue top tube may be drawn.

When you have high blood pressure you cannot donate blood while the blood pressure is high because it can affect your health and the blood may flow to fast out of your body as well.

Once your blood pressure has decreased though then you can donate blood.

Acceptable blood pressure rate for blood donation is below 180 systolic (first number) and below 100 diastolic (second number) at the time of donation.

Even though, the donor is on regular medications, one must understand that medications for high blood pressure do not disqualify you from donating blood.

Provided, you don’t have side effects related to your medication.

Also, the person shouldn’t be suffering from other co-morbid diseases associated with hypertension.

People who have fluctuating blood pressure with irregular treatment must stay away from donating.

As a general guide: high blood pressure is considered to be 140/90mmHg or higher (or 150/90mmHg or higher if you're over the age of 80) ideal blood pressure is usually considered to be between 90/60mmHg and 120/80mmHg.

The stroke level for high blood pressure is any blood pressure reading above 180/120 mmHg.

Blood pressure readings above 180/120 mmHg are considered stroke-level, dangerously high and require immediate medical attention.

Aspirin can help lower blood pressure but aspirin does not lower blood pressure immediately.

It takes a few hours after taking the aspirin before it starts to lower your blood pressure and regularly taking aspirin can help keep your blood pressure from getting too high and an aspirin a day can help prevent blood clots and prevent heart disease, heart attacks, strokes etc.

Some ways ways to bring your blood pressure down quickly are to exercise, avoid too much salt, drink some lemon water, eat garlic or take some garlic extract supplements.

Laying down and taking some deep breaths can also help lower your blood pressure.

If your blood pressure is elevated and you want to see an immediate change, lie down and take deep breaths.

This is how you lower your blood pressure within minutes, helping to slow your heart rate and decrease your blood pressure.

When you feel stress, hormones are released that constrict your blood vessels.

Drinking water can also bring your blood pressure down and help maintain your blood pressure.

Keeping well hydrated by drinking six to eight glasses of water daily (even more if working in hot and humid conditions) is beneficial for the blood pressure.
