After the completion of this module you will be able to:

Many of the drugs used in critical care areas effect physiologic functions: heart rate, cardiac output, blood pressure, respirations, and renal function. In general these drugs have a rapid onset and a short duration. Some of these drugs are administered on a sliding scale to elicit a physiologic response. In other words, the healthcare provider must change the flow rate of the drug from time to time depending on how the patient is responding. This rate adjustment is known as titration. The healthcare provider must constantly monitor the patient's vital signs in order to titrate the dose (rate of administration) of a drug correctly.

Patients who are critically ill typically receive drugs that are dosed in:
- mg/hr
- mcg/hr
- mg/kg/min
- mg/kg/hr

SAFETY ALERT: Incorrect dosing can cause catastrophic problems including death. To safeguard against incorrect dosing healthcare providers should:

Healthcare providers take these precautions when these IV infusions are initiated and when titration changes are necessary.
