Guides

Guides for practice, recording and review.

Ten practical guides on the mechanics of mock codes and resuscitation rehearsal: the intervals worth tracking, the pauses worth counting, the roles worth assigning and the timeline worth reviewing afterwards with your team. Written for the people holding the clipboard during a practice session.

Before you read any of this

These guides are educational material about process, recording and rehearsal. They are not clinical guidance, not a protocol and not a substitute for training. They contain no doses, no joule settings and no treatment recommendations. Resuscitation practice is defined by your institution's protocol and by current AHA or ERC guidelines. MedCode is a practice and training tool. It does not interpret rhythms, recommend medications, perform clinical calculations or tell anyone what to do next. It is not a medical device.

MedCode is a practice and training tool. It is not a medical device, not clinical decision support, and not a substitute for your institution's required documentation or protocol. Any use during a real event is the individual clinician's own professional judgement.

Timing and review.

The things a stopwatch cannot tell you after a mock code: how long compressions actually lasted, how consistent the pacing was, and whether dose intervals stayed on target.

CPR quality

Reviewing Compression Fraction After a Mock Code

How compression fraction is calculated, where the pauses hide in a timeline, and how to use the session record to identify habits worth changing.

Timing

Tracking a Repeating Dose Interval in a Code

Why repeating intervals are easy to lose track of, how a dedicated timer helps keep them consistent, and what to look for in the session timeline afterwards.

Read the guide

CPR quality

Using a Metronome to Practise Compression Pacing

The target rate, how compression speed drifts without a cue, and how to use an audible beat during skills practice to build consistent pacing.

The record

What to capture and why.

Memory compresses and reorders a twenty-minute session. Everything you want to review in the debrief has to be captured while the mock code is running, or it is gone.

Documentation

Recording a Code: What Belongs in the Timeline

The categories a code timeline needs to capture, why timestamps drift when reconstructed from memory, and how to log entries as they happen during practice or training.

Read the guide

Reference

How to Log Medications During a Code

The medications that show up in a code timeline, their reference concentrations, and how to use adjustable steppers to record the amount given.

Read the guide

Rhythms

Logging Rhythm Changes and Shocks in a Code

VF and pulseless VT versus PEA and asystole, why rhythm at each check matters for the record, and how to log rhythm changes and shocks as they happen.

Read the guide

The team

Training and debrief.

Most mock code chaos is a role-assignment problem, not a knowledge problem. Eight people arrive and four of them do compressions. Setting roles before you start makes the practice session worth repeating.

Team

Assigning Roles for a Mock Code or Practice Session

Team leader, compressor, airway, access, meds, recorder and timekeeper — what each role does and where to assign them before a practice session starts.

Read the guide

Training

Running a Mock Code: A Practical Guide

How to set up an in-situ mock code, what to capture while it runs, and how to use the timestamped record to make the debrief specific and useful.

Read the guide

Debrief

Reviewing a Mock Code With a Session Timeline

Hot debriefs versus cold, a structure that fits in five minutes, and how a timestamped timeline makes the review specific rather than general.

Read the guide

Tools

Choosing what to use.

A phone stopwatch, a paper sheet, a simulation platform log or a purpose-built practice timer. Each is right for some training settings and wrong for others.

Comparison

Choosing a Code Blue Timer App: What Matters

Stopwatches, generic interval timers and purpose-built code timers compared — and what matters when choosing a tool for practice, training or personal use.

The single guide that frames every other one: what a code timeline has to capture, and why the reconstruction problem is the root of most training and review challenges.
