The pump

Your heart is a pump. Every beat sends blood to your brain and body, carrying the oxygen they need.

Cardiac arrest

In cardiac arrest the heart stops pumping. Blood stops, and the brain gets no oxygen. Damage can start in four minutes.

You are the pump

Now you are the pump. The heart sits between breastbone and spine. Each push squeezes blood out; each rise lets it refill.

Depth

Adult compressions go two to two point four inches deep. That’s the green band.

Watch

Watch a tired rescuer. After a minute and a half to two minutes, depth starts to slip. Too shallow, and less blood moves.

Push hard

Push hard. Every compression lands in the band. With a partner, switch compressors about every two minutes. That is about when tired hands start to slip.

Push fast

Push fast: one hundred to one twenty compressions a minute. Keep pauses short. When you stop, the pressure you built drops almost at once.

Thirty and two

Thirty compressions, then two breaths. That is the adult cycle, alone or with a partner, until an advanced airway is in.

Check

One rescuer, adult patient. What is the compression-to-breath ratio?

  1. 15 : 2
  2. 30 : 2
  3. 5 : 1

Answer: 30 : 2. 30 : 2 for any adult without an advanced airway, one rescuer or two. Once an advanced airway is in, compressions go nonstop with one breath every 6 seconds.

Recoil

Let the chest come all the way back up every time. Leaning on it keeps the heart from refilling fully.

Questions

How does the practice exam work?

It adapts: harder when you’re right, easier when you’re not. At the end you see your readiness in each of the five domains.

Does this replace my EMT course?

No. To sit for the NREMT you need a state-approved EMT course with in-person skills and clinical training.

Is this affiliated with the National Registry?

No. ClassMetric is independent prep, and its questions are original.

When does it open, and what will it cost?

Lesson 1 is free now. The full class opens at $34, paid once.
