Glasses That See Blood



Tired of the nurse stabbing you because s/he can't find a vein? These new glasses by 2AI Labs may help. They have color filters designed to spot blood. The developers anticipate that medical professionals will use them in three ways:

– (i) a vein-finder, or oxygenation-isolator, that amplifies perception of oxygenation modulations under the skin (and eliminates perception of variations in the concentration of hemoglobin),
– (ii) a trauma-detector, or hemoglobin-concentration-isolator, that amplifies perception of hemoglobin concentrations under the skin (and eliminates perception of variations in oxygenation), and
– (iii) a general clinical enhancer, or oxygenation-amplifier, that combines the best features of the first two; it eliminates neither signal (i.e., it retains perception of both variation in Hemoglobin oxygenation and concentration), and only amplifies perception of oxygenation.

Problems having blood drawn? It's NOT always the phlebotomist's fault.

1. If the nurse can't get it ask for a phlebotomist. Nurses have lots of responsibilities while blood is pretty much all we do & if we're not good we're unemployed.

2. DRINK WATER! DRINK WATER! DRINK WATER! When they tell you to fast that DOES NOT mean no water. Water has nothing in it that will affect bloodwork & the more fluids in your body the better. Start doubling up the day before & continue until after the blood is drawn.

3. Don't squeeze your hand when they stick the needle in. This goes against convention but I've been doing this for 20 years & have not had anyone squeeze for at least 15 years. Squeezing increases the chances of the muscle "rolling" over the muscle. It also can result in a high potassium level as that's natural chemical reaction in a muscle contraction.

There you have it! Unless it is an emergency (life threatening) situation these tips should help anyone have lab tests drawn easier. If I saw some1 trying to use glasses I'd get up & leave.

Ugh, I remember in 1998 major surgery, I had to get 13 shots to find a good vein. I woke up and that IV needle was above my crotch! GAH!
