This chapter covers all the steps recommended for safe phlebotomy and reiterates the accepted principles for blood drawing and blood collection (31). The chapter includes background information (Section 2.1), practical guidance (Section 2.2) and illustrations (Section 2.3) relevant to best practices in phlebotomy.
To calculate the gtt/min, multiply the infusion rate (mL/hr) by the IV drop factor (gtt/min) found on the IV tubing, then divide by the infusion time in minutes. For example, a fluid that is to be infused at a rate of 75 mL/hr via 15 gtt tubing would infuse at a rate of 19 gtt/min [ (75 × 15)/60 = 18.75 gtt/min].
25 Ιουλ 2023 · Peripheral intravenous (IV) lines, catheters or cannulas are indwelling single-lumen plastic conduits that allow fluids, medications and other therapies such as blood products to be introduced directly into a peripheral vein.
27 Απρ 2023 · Healthcare providers use peripheral IV lines to draw blood and give treatments, including: IV fluids. Medications, such as antibiotics. Blood transfusions. Liquid nutrition (total parental nutrition). The most common peripheral IV sites include the back of your hand, inner elbow and foot. In infants, the scalp is the easiest placement.
Intravenous (IV) therapy is an important part of clinical care. It can be used to restore fluids, administer blood products or medications, or serve as an alternate route for nutrition when the gastrointestinal tract is not functioning adequately.
30 Οκτ 2023 · Peripheral intravenous (IV) catheters allow for the safe infusion of medications, hydration fluids, blood products, and nutritional supplements. First-time success rate for peripheral IV placement ranges from 65 to 86 percent [1].
The flow of fluids through an IV catheter can be described by Poiseuille’s Law. It states that the flow (Q ) of fluid is related to several factors: the viscosity (n) of the fluid, the pressure gradient across the tubing (P), and the length (L) and the inner diameter(r) of the tubing.
