We have one of those lights but it doesn’t help me at all! Lol if you have to turn out the lights to use it I’m blinded when they come back on lol! I start by seeing the veins so I’m lost on African American or dark skinned people and those whose veins run deep. We have a dedicated picc team so that’s what we do..call them for piccs. For ivs we try twice then ask for help. Sometimes our icu nurses come and try if not too busy. Sorry no better help :(.
