Rule of 6 | Makes calculation of initial dose/rate easy | Requires individualized concentrations, resulting in increased frequency and complexity of preparation |

| Facilitates volume adjustment for low-weight patients | Often difficult to use when making dose/rate changes |

| Practitioners must remember slightly different formulas for different medications |

Standard concentrations | Fewer concentrations prepared | Requires more complex initial dose calculation |

Reduces number of steps required to prepare drip | Often difficult to use when making dose/rate changes |

| Simplifies medication ordering | Limits choices of volume and rate that can be delivered |

| Reduces costs |

| Improves pharmacy quality control | |

Dosing charts | Minimizes need to perform calculations, reducing risk of calculation errors | Substitutes risk of perceptual tracking errors for risk of calculation errors |

| | Limited range of values unless tables are large |

Smart pumps | Eliminates need for calculations | High initial capital expenditure |

| Alerts for out-of-range entries | Likelihood of selection errors increases with number of different concentrations available in drug library |

| Drug libraries and default settings facilitate selection of correct medication and dose |

| Better information display and feedback |
