The use of IV drugs comes with the risk of undesirable effects when certain drugs come in contact with each other. Drugs that produce an undesirable effect are considered to be incompatible. Drug incompatibility occurs when one drug is not of suitable composition to be mixed with another drug, resulting in chemical alteration or destruction of one or both drugs. Incompatibility reactions occur inside a fluid container or IV line. Some drug incompatibilities result in precipitation, which is the formation of solids from a liquid solution that can be visibly seen as crystals, haziness, or turbidity. Others cannot be seen, but have chemical...

BLS Childbirth

It is very rare for a pregnant woman to call for emergency services to assist with childbirth unless there are unusual circumstances, such as going into labor in an unusual place, or not having the ability to get to the hospital in time. For this reason, the unfamiliarity, as well as the possibility of complications of delivering a baby, can be stressful for the EMS provider. Remember, however, childbirth is a natural process and usually only requires facilitation of what is already happening. Often times, delivery in the field occurs in uncontrolled environments, so it is important to have a good understanding of the delivery process...

Scene Safety

Every EMS call begins with scene safety. In fact, it starts long before you ever respond to your first call. It starts with your training. Any EMS provider who has ever taken an EMS course or certification exam knows the term “BSI, Scene Safe”. If that little phrase is not verbalized before performing the patient assessment, it’s an automatic fail. That is because scene safety is the very first priority when responding to any emergency and it's extremely vital in your role as an EMS provider. Although EMS providers have an obligation to treat sick or injured patients in a timely manner, they are of no use if they become a patient as well,...

Mean Arterial Pressure

What is blood pressure?

As the heart contracts, blood is forced out of the left ventricle and into the aorta and distributing arteries. The force created by the heart's contraction generates pressure as blood pushes against the walls of the vessels. This is known as blood pressure and consists of two readings: the maximum (systolic) and minimum (diastolic) pressures. The maximum pressure occurs as the heart contracts, and the minimum pressure occurs as the heart fills back up with more blood. The normal blood pressure for an adult is 120/80 mmHg. 

What is Mean Arterial Pressure (MAP)?

MAP is the measurement that...

About Sepsis

Sepsis is a serious medical condition that is caused by a systemic immune response to an infection in the blood stream. If not rapidly treated, the infection can lead to septic shock. Septic shock is a form of shock that falls under the category of ‘distributive shock’ as it leads to a decrease in overall blood pressure due to widespread vasodilation throughout the entire body. The decrease in blood pressure leads to decrease in oxygenation of tissues that results from the inflammatory response. Lack of oxygenation to the tissues will lead to cell damage and eventually organ failure as they are deprived of the nutrients they need for...

Ventricular Fibrillation ECG

In this ECG video, we review the characteristics of ventricular fibrillation or Vfib.

Beck's Triad

This video reviews the three components of Beck's Triad: low blood pressure, distended neck veins, and muffled heart tones. These components should lead you to suspect cardiac tamponade.

SAMPLE History

This EMTprep video reviews how to take and record a SAMPLE medical history.


This video provides a brief overview of what is happening on the cellular level when someone is experiencing anaphylaxis. We also go over what to look for when you respond to someone who is experiencing this life-threatening disorder.
