Waveform capnography

video stub

A new tool for life support, waveform capnography allows you to assess the effectiveness of compressions and stability of the victim. This is effective for the perfusing patient and during cardiac arrest.

King Airway usage

video stub

Introduction to and proper usage of King Airway for advanced airway creation. Blocks air from escaping to esophagus or mouth and guides into lungs.

video stub

Drills straight to the core of IO administration, shows the most common placement and how get medication access.

Arrhythmia Interpretation / Monitor Tech

Normal sinus rhythm

video stub
  • Heart Rate = 60-100 beats per minute
  • Regular Rhythm – slight irregularities are normal
  • P waves precede each and every QRS complex
  • The PR interval is between 0.10 and 0.20 seconds
  • The QRS complex is within normal limits 0.08 - 0.12 seconds
  • There is a QRS complex following each and every P wave

Asystole

video stub

Asystole – is the absence of electrical and mechanical activity in the heart. P waves may be present but there are either no QRS complexes or less than 15 QRS complexes per minute. This rhythm usually is an indication of death. This is the rhythm that is routinely referred to "flat line."

PSVT

video stub

Is used to describe any rhythm that originates above the ventricles that is fast. The result is a fast narrow complex tachycardia. SVT is used when the rhythm is going so fast that it is impossible to distinguish P waves or PR intervals or even regularity of the strip.

Atrial fibrillation

video stub

Any rhythm that is grossly irregular and you cannot find P waves an accurate guess would be atrial fibrillation. A good way to tell the difference between atrial flutter and atrial fibrillation is that if you were asked to count the atrial rate it would be possible in atrial flutter because there are discernible flutter waves. It would not be possible to count an atrial rate in atrial fibrillation.

2nd Degree AV Block Mobitz I

video stub

Second degree AV block Mobitz I (Wenckebach). The only difference in this ECG strip and that of sinus rhythm is that the PR interval is longer. This is because it is taking longer for the impulse to travel from the SA node to the ventricles to cause depolarization. This AV block is usually benign although in patient’s with heart disease it can signal that more advanced AV blocks may be just around the corner.

2nd degree AV block Mobitz II

video stub

Second degree AV block: Mobitz type II. The key to this heart block is to remember that when the P wave is conducted all of the PR intervals are the same (vs. type I in which they lengthen). This is an advanced heart block and the patient will always receive a permanent pacemaker prior to discharge if Mobitz II or third degree heart block is documented.

Sinus bradycardia

video stub

You will note that the only difference between normal sinus rhythm and sinus bradycardia is the heart rate. When you first learn how to interpret rhythms pay attention to the name (not the abbreviation) and it will give you a hint as to what it looks like. Rhythms are named first by the pacemaker site, then by the ectopic focus (if there is one) and then by the heart rate. For example, sinus bradycardia originates in the sinus node and the heart rate is less than 60 (bradycardia).

Sinus tachycardia

video stub

Sinus tachycardia originates in the sinus node and is faster than 100 beats per minute. Sinus tachycardia is always compensating for something. For example, if a patient is bleeding, the first thing the body will do is to increase the heart rate so that the blood that is left is pumped around faster.

Atrial flutter

video stub

Atrial flutter occurs when the atrium fires at such a fast rate that P waves become indiscernible. They instead blend together to become "flutter or F waves". In atrial flutter, the atria do not contract putting the patient at high risk to develop blood clots originating in the appendage of the atria.

Third degree heart block

video stub

Third degree heart block ("complete block") can be asymptomatic; however always requires the implantation of a permanent pacemaker because it represents complete failure of the AV node leaving only one very non efficient pacemaker left (the ventricles).

Torsades de pointes

video stub

This is a polymorphic VT that has the distinct characteristic of QRS complex coming into and out of the isoelectric line. This can quickly degrade into VF leading to sudden death without intervention or revert to normal sinus rhythm.

Ventricular fibrillation

video stub

Ventricular fibrillation always represents a life threat. Hundreds or thousands of focuses are firing at the same time causing chaotic motion of the ventricle. If you were to look into the chest of a patient in ventricular fibrillation the heart would look as if you had Jello placed in a bowl and then bumped the bowl.

Ventricular tachycardia

video stub

Because the rhythm is not efficient, and fast it rarely without symptoms. In fact, ventricular tachycardia can be a rhythm of cardiac arrest without pulses.
