One-Compartment Model: IV Infusion01:09

One-Compartment Model: IV Infusion

272
Intravenous (IV) infusion is often utilized when continuous and controlled drug delivery is necessary, such as during surgery or in the treatment of chronic diseases. This method offers numerous advantages, including immediate drug action, precise control over dosage, and bypassing the first-pass metabolism.
The one-compartment model for IV infusion uses mathematical equations to describe the rate of change in drug quantity in the body. At steady-state or infusion equilibrium, the drug input...

Two-Compartment Open Model: IV Infusion

320
A two-compartment model is a vital tool in pharmacokinetics, providing an essential understanding of drug behavior, especially for those administered via zero-order intravenous infusion. This model outlines two compartments: the central compartment, where elimination occurs, and the peripheral compartment.
The model illustrates the decrease in plasma drug concentration from the central compartment with a specific equation. It shows that under steady-state conditions, the drug's input rate...

One-Compartment Open Model for IV Bolus Administration: Estimation of Clearance

134
Clearance is a key pharmacokinetic parameter that quantifies the volume of body fluid from which a drug is entirely removed within a specific time frame. It is crucial in assessing how a drug is eliminated from the body and has critical clinical applications.
In the one-compartment open model for intravenous (IV) bolus administration, clearance is estimated by dividing the elimination rate by the plasma drug concentration. This equation leverages the elimination rate constant and the apparent...

One-Compartment Open Model for IV Bolus Administration: General Considerations

305
The one-compartment model is a pharmacokinetic tool that models the body as a single, uniform compartment, facilitating the understanding of drug distribution and elimination. This model is particularly beneficial for intravenous (IV) bolus administration, where the drug rapidly circulates throughout the body.
The drug's presence in the body is defined by an equation representing the difference between the rates of drug entry and exit. Key parameters—elimination rate constant,...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

288
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Two-Compartment Open Model: IV Bolus Administration

679
The two-compartment model for intravenous (IV) bolus administration illustrates drug distribution in the body, subdividing it into central and peripheral compartments. This model operates on the concept of two-compartment kinetics. The drug's plasma concentration shows a bi-exponential decline following IV bolus administration, signaling the presence of two disposition processes: distribution and elimination.
The disparity between drug input and the sum of drug transfer rates between...

Area of Science:

  • Nursing Informatics
  • Patient Safety
  • Medical Device Technology

Background:

  • Intravenous (IV) smart pumps are critical for safe medication administration.
  • Manufacturer-specified setup protocols aim to optimize IV smart pump functionality and patient safety.
  • Understanding real-world adherence to these protocols is essential for identifying areas of improvement.

Purpose of the Study:

  • To assess adherence to manufacturer-required setup procedures for the Baxter Spectrum IQ IV smart pump.
  • To evaluate IV smart pump system setup practices at the point of care in an acute care setting.

Main Methods:

  • An observational, noninterventional study was conducted in a 285-bed acute care hospital.
  • A single observer documented adherence to Baxter Spectrum IQ setup requirements during 200 medication administrations.
  • Data collection focused on IV smart pump position, primary infusion bag position, and secondary medication infusion bag position.

Main Results:

  • Overall adherence was low: 6.5% for IV smart pump position and 6.5% for primary infusion bag position.
  • Adherence for secondary medication infusion bag position was higher at 69.5%.
  • Significant deviations from required setup were observed in critical care and medical-surgical units.

Conclusions:

  • Adherence to required IV smart pump setup, especially for head-height dependent components, is challenging in clinical practice.
  • Low adherence rates highlight potential risks to patient safety during medication administration.
  • Human factors-engineered technology solutions are needed to enhance the reliability of IV smart pump setup and improve patient safety.
