Code blues activate fear, uncertainty, and cognitive overload

New nurses often freeze because they don’t know where to focus

The goal is not perfection — it’s having a plan

Most people believe codes are sudden

Research shows most patients show early signs of deterioration hours before arrest

A code is often the final stage of a slow decline, not a surprise event

A patient who “just doesn’t look right”

Rapid breathing that keeps trending upward

Subtle agitation, restlessness, or picking at sheets

A patient expressing a sense of impending doom

These signs are often dismissed — but they are critical red flags

Experienced nurses prepare the room assuming a code could happen

This mindset shift alone improves outcomes

Prevention is the most powerful code blue skill

Turn suction on and set it up before it’s needed

Take the bag-valve mask out of the packaging ahead of time

Make sure oxygen is ready and flowing

Ensure the bag includes a PEEP valve for ICU patients when needed

Locate the CPR lever on the bed at the start of the shift

Use a step stool if needed to deliver effective compressions

Minimize interruptions to compressions

Move quickly but deliberately

Flow matters more than frantic activity

Shock when indicated, then immediately resume compressions

Don’t stop to stare at the monitor

Rotate compressors frequently to maintain quality

Check the femoral pulse during compressions to avoid wasted pauses

Write medication times and events on a visible surface

Use a single container to collect empty medication packaging

This creates an instant audit trail and simplifies documentation

Use pressurized saline to flush medications rapidly

Reduce clutter and wasted time fumbling with syringes

Speed and organization matter more than perfection

ICU arrests are usually secondary to another failure

Think through respiratory, volume, electrical, and metabolic causes

Draw labs early to identify hypoxia, acidosis, or high potassium

Use bedside ultrasound when available to identify reversible causes

“Do you want us to do everything?” is a misleading question

Clear, honest language helps families understand what CPR truly is

Early conversations reduce moral distress and futile codes

“The patient is already dead. You cannot make them more dead.”

This removes fear of making mistakes

Panic fades when process replaces emotion

Take sixty seconds after every code

Identify what worked and what didn’t

Immediate reflection builds confidence faster than charting alone

Code blue confidence comes from preparation, not experience alone

You don’t need to know everything — you need a framework

These hacks turn chaos into control
