How do you improve venous access?
To improve venous access, consider using warming techniques to dilate the veins, ensure proper positioning of the patient's limb, use a tourniquet if needed, select appropriate size of catheter/needle, and utilize ultrasound guidance for difficult access. Additionally, staying hydrated and encouraging physical activity can help maintain healthy veins for future access.
