VTBI stands for Volume To Be Infused, and it refers to the amount of fluid or medication that an infusion pump is programmed to deliver to a patient over a set period of time. The VTBI is set by a healthcare provider based on the patient's medical condition, weight, and the specific medication or fluid being administered.
For example, suppose a patient requires a dose of antibiotics that should be delivered over 1 hour. In that case, the healthcare provider may program the infusion pump with a VTBI of 100 mL, meaning that the pump will provide 100 mL of the antibiotic over 1 hour. The infusion pump will automatically stop once the VTBI has been reached, to ensure that the patient receives the correct dose of medication.
The VTBI is a crucial feature of infusion pumps, as it helps to ensure accurate dosing and reduce the risk of over or under-dosing. It is one of several programming parameters that can be set on an infusion pump, including infusion rate, bolus doses, and pause times, depending on the needs of the patient and the medical application.
