WHICH IS YOURS

Which training is yours?

Recognising the deteriorating patient

Ward teams and new graduates read the chart, enter the room and pick up early warning signs on the monitor before calling the rapid response or MET team. Advanced life support too, with a BLS manikin.

See the lesson example →

Resuscitation courses — BLS, ACLS, ALS, ILS, PALS

Rhythm checks, defibrillation, synchronised cardioversion, voice-guided AED. A BLS refresher runs on the free version alone.

See the lesson example →

Nursing schools and physical assessment labs

Hide the values and let students reason from auscultation, pupils and vitals. Works with a standardised patient, one iPad per group.

ISSUE

From being told
to noticing.

In a low-fidelity simulation, the instructor has to announce the patient’s condition out loud. In real practice, nobody tells you that something is wrong.

Training until now

  • The instructor reads out the vitals
    “The blood pressure is now 80/40.”
  • Learners only react to what they are told. The noticing step is skipped
  • Showing a monitor means a high-fidelity simulator — expensive and a lot of setup

Training with Code Blue Monitor

  • Learners gather information from the monitor themselves
  • They notice the change and decide what to do
  • Your own iPad, iPhone and BLS manikin, in the room you already use

In practice, people stumble before the response — at the noticing. This turns that step into something learners can practise.

With Code Blue Monitor, the sequence is the same as in practice.

When the instructor makes a change on the remote, the monitor in front of the learner actually changes.

STEP 01Look

Turn to the monitor and read the display.

STEP 02Notice

Sense that something is different and react.

STEP 03Assess

Go to the patient and gather more information.

STEP 04Decide

Work out what is happening and what is needed.

STEP 05Act

Call for help, report, and begin treatment.

AT A GLANCE

An ECG simulator, a defibrillator trainer and a patient monitor simulator, in one iPad app. A rhythm and defibrillator simulation app for ACLS, ALS / ILS, BLS and nursing simulation training. 35 ECG rhythms, defibrillation, transcutaneous pacing, 12-lead ECG, blood gas, imaging, auscultation and pupil examination, controlled from an iPhone remote. Works with any manikin, no proprietary hardware, no Wi-Fi.

One iPadThe monitor the learners see. It also runs on an iPhone
One iPhoneThe instructor’s remote. The free app is enough — a personal phone works
One-minute setupEnter a four-digit room code. No Wi-Fi, no internet
HOW IT WORKS

Change it in your hand. See it change in front of them.

The instructor never has to slip behind the learners. Advance the scenario from the remote while watching their faces and movements.

INSTRUCTOR — iPhone
iPhone remote: rhythms and vitals controlled from the hand

35 rhythms, sliders for BP, SpO₂, respiratory rate and heart rate, and one-tap scenario presets.

LEARNER — iPad
Monitor showing ventricular fibrillation with the defibrillator charged

Waveforms change, numbers move, alarms sound. Hide the control panel and it sits in front of learners like a real monitor. Learners operate the defibrillator dial, charge and shock themselves.

Setup takes about a minute. Type the 4-digit room code shown on the iPad into the iPhone. No Wi-Fi router, no internet. Every feature also works on a single device.

FEATURES

What each feature lets you
simulate.

AED MODE — NEW

AED with voice prompts

Turn the dial to AED and the device talks learners through it: attach the pads, analysing, shock advised, press the flashing button, start CPR, and a re-analysis every two minutes. Voice prompts in English, Japanese and Spanish. No shock limit, even in the free version.

BLS and ward-staff training, first responder practice before the code team arrives

ECG — 35 RHYTHMS

Electrocardiogram

From sinus rhythm to VF, pulseless VT and asystole, every type of AV block, and ST elevation. Heart rate is measured from the R–R interval, so in Wenckebach or bigeminy the displayed rate differs from the actual pulse.

Builds the habit of checking the waveform and the patient instead of trusting the number

VITALS

Heart rate, BP, SpO₂, respiratory rate

Change them continuously with sliders on the remote. Build a seamless course from gradual deterioration to cardiac arrest.

Judging rapid response criteria, recognising early warning signs

DEFIB / PACING

Defibrillation and transcutaneous pacing

Select energy with the dial, hear the charge tone, deliver the shock. The dial is laid out like a real defibrillator — off, monitor, AED, internal discharge, energy and pacing — so learners practise the same hand movements. Synchronised cardioversion waits for an R wave. Pacing starts at 0 mA and you raise the output until you confirm capture.

Procedure fluency, judging electrical capture, understanding SYNC

CHART

52 patient chart cases — advanced step by step

Fifty-two ward patients, each presented like a real chart with physician and nursing notes, labs, imaging and orders. Filter by the learners’ unit — surgical, medical, neurosurgical, cardiology, obstetrics, dialysis and more. A case starts at a stable point; each time the instructor presses Next, vitals and rhythm change over several seconds to follow the chart, and blood gas, imaging and breath sounds follow the timeline. Press Arrest to move the patient into cardiac arrest at any point, then ROSC to restore circulation. Every case includes an instructor debriefing guide: pathophysiology, expected actions, SBAR example and discussion questions.

If the team responds in time, the patient holds on; if not, they arrest. The outcome follows what the learners do

AUSCULTATION

Breath and heart sounds

Six breath sounds (wheeze, stridor, coarse crackles and more) and six heart sounds (S3, valvular murmurs, pericardial rub and more). Heart sounds are timed to the ECG on screen and fall silent when there is no pulse.

Physical assessment practice, respiratory and circulatory evaluation

AED mode: the dial set to AED, charging, with the shock button ready

WHERE IT FITS

Between a basic monitor app and a hardware simulation system.

Basic monitor apps show vitals and a few rhythms. Tablet-based hardware systems add branded device screens and kits, usually with quote-based or subscription pricing. Code Blue Monitor sits in between: the depth of a teaching system on the iPad and iPhone you already own.

EXAMPLES

How it runs in next month’s session.

Look at the flow rather than the feature list. All four run on one iPad, one iPhone and a BLS manikin (or a standardised patient). You can practise advanced life support end to end without a high-fidelity simulator.

NEW GRADUATE NURSES — 30 MIN

Read the chart, enter the room, report

① Learners read the chart on the iPad for 5 minutes (e.g. post-op day 1, COPD) → ② They enter the room; the monitor shows SpO₂ 90%, respiratory rate 28 → ③ Coarse crackles on auscultation; they raise the oxygen → ④ The instructor presses Next to deteriorate — or lets SpO₂ recover if the response is good. If the team is too slow, press Arrest → ⑤ SBAR report to the physician role → ⑥ Open the chart’s Debrief tab to review the pathophysiology and expected actions

Features used: chart case (post-operative respiratory failure), sensor-based display, breath sounds, vital sliders, debriefing guide

BLS REFRESHER — 20 MIN (FREE VERSION)

Unresponsive → AED → ROSC

① Put the iPad next to the manikin; the instructor sets VF from the iPhone → ② Learners check response and breathing, call for help, start CPR → ③ Turn the dial to AED and follow the voice prompts: pads, analysis, shock → ④ During the 2-minute CPR cycle the instructor restores sinus rhythm → ⑤ Re-analysis says “no shock advised”; pulse check → ⑥ Debrief from the event log: time to CPR, time to first shock

Features used: VF, voice-guided AED, waveform changes during CPR, event log (all in the free version)

ADVANCED LIFE SUPPORT (ACLS / ALS) — 40 MIN

With a BLS manikin: from defibrillation to drugs and post-ROSC care

① Monitor attached; learners read the rhythm (VF) → ② CPR and a 150 J shock, rhythm check every 2 minutes → ③ Adrenaline after the third shock, then amiodarone (drug times logged) → ④ The instructor changes VF to pulseless VT and then PEA and asks for the differential → ⑤ ROSC: sinus tachycardia, BP 88/52, SpO₂ 92%. Open the 12-lead and read the inferior infarct → ⑥ Post-ROSC care (oxygen, blood pressure, temperature) reported with SBAR

Features used: VF, pulseless VT, PEA, unlimited shocks, synchronised cardioversion, 12-lead ECG, event log — no high-fidelity simulator needed; a BLS manikin is enough

PHYSICAL ASSESSMENT — 30 MIN

Reason from auscultation, pupils and vitals

① Learners are told only “the patient is short of breath”; the monitor values are hidden → ② They attach the SpO₂ probe: 91%; measure the BP: 150/95 → ③ Wheeze (or coarse crackles) on auscultation; an S3 on the heart sounds → ④ Pupils normal, fully alert → ⑤ The group debates heart failure versus asthma and opens the blood gas and chest X-ray to check → ⑥ The instructor reveals the values; the case’s debriefing guide ties the pathophysiology together

Features used: hidden values, sensor-based display, breath and heart sounds, pupils, blood gas, imaging, chart case — a standardised patient (a learner) works instead of a manikin

Also: in-house emergency response training (on the ward, including short night-shift sessions) · new graduate programmes (reading, reporting, calling for help) · rapid response education · nursing schools and universities (several iPads, one per student group) · OSCEs (hidden values)

These four lesson plans, with pricing, licensing, how to buy through Apple Business Manager and the requirements, are in the evaluation pack (PDF, 7 pages) — ready to forward to your manager or procurement.

IN PRACTICE

Your usual training room,
plus a monitor.

Keep the BLS manikin and bed you already have. Adding a monitor turns it into a scene where learners notice the abnormality themselves.

ORIGIN

Born in the classroom,
not in a software company.

Created by the instructors themselves, out of need, while running NCLS (Nursing Cardiac Life Support), an emergency response course for nurses in Japan.

1,500+ participants

NCLS is a one-day course for nurses where monitor interpretation, BVM ventilation, reporting and drug preparation are learned through simulation.

As of 1 September 2026. Course participants, not app installations
NP-designed

Designed under the supervision of our founder, a nurse practitioner and former certified emergency nurse, from both a clinical and a teaching perspective.

In daily use

Used in every NCLS course simulation. Features were added as they were needed in training, and anything unnecessary was removed.

From App Store reviews

★★★★★　In a different league from typical simulators
We use it for ACLS and in-house training. We used to use an app from overseas, but the monitor sounds were off and we couldn’t fine-tune anything. This app is very versatile and reaches exactly the places other tools miss. You can tell the developer is a practising educator. Highly recommended if you want realistic, true-to-the-ward simulation.

ささき.jp (October 2026)

★★★★★　Feature-rich and practical
We used it for emergency response simulation. Because the remote changes the patient’s condition in real time, we could develop the scenario around the learners’ decisions and actions — a genuinely practical session. With so many features it took a little time to get used to at first, but after a few sessions it felt natural.

@s.1212 (October 2026)

★★★★★　Works for any training or study session
You can reproduce the vital signs of a deteriorating patient freely, so it works for all kinds of training. It feels designed for emergency response courses — very flexible and easy to set up many different conditions.

かずおじぃ (October 2026)

★★★★★　Just what I’d been hoping for
A simulator that gets right to the things you always wished you had!

ニケ12 (October 2026)

Reviews posted on the Japanese App Store, translated from Japanese (some shortened).

From instructors who use it

It covers breath and heart sounds as well as ACLS-style training, so it works for physical assessment sessions too. Setting up a high-fidelity simulator is a lot of work; with an iPad, a BLS manikin or a simulated patient you can recreate a clinical scene.

NCLS instructor (nurse)

We used it on an NCLS course. Since it can show breath sounds and pupils as well, it looks useful for physical assessment training too.

FAQ

Before you buy.

Do I need the hospital Wi-Fi? What if the devices will not connect?

No. The devices connect directly to each other, so no Wi-Fi router or internet is used. Keep Wi-Fi and Bluetooth switched on on both the iPad and the iPhone, and allow the app to use the local network. If they will not connect, quit the app on both devices, open it again and re-enter the same room code. See the user guide for details.

What is the difference between the in-app purchase and Code Blue Monitor Pro? Which should I buy?

The features are the same; only the way you buy differs. For your own iPad or iPhone, download the free app and unlock the full version inside it. For deploying to several devices in an institution, choose Pro, which can be bought in volume through Apple School Manager or Apple Business Manager (the free app's in-app purchase cannot be bought in volume). If you have already unlocked the full version on a device, you do not need to buy Pro for it as well.

Can hospitals and schools buy it? Is institutional use possible?

Yes. The institutional edition, Code Blue Monitor Pro, supports volume purchasing through Apple School Manager and Apple Business Manager. The free app's in-app purchase cannot be bought in volume, so choose Pro for managed devices. For larger deployments or invoicing, please contact us. For evaluation, we can also issue a code for one month of every feature, free.

Can I run training with the free version alone?

Yes. It is meant for ward-level study sessions and BLS refreshers. Sinus rhythm, VF, pulseless VT and asystole, up to three shocks per scenario, the iPhone remote, vital-sign control and one chart case (post-operative respiratory failure) are all free, so with a BLS manikin and an iPad you can run the whole sequence of noticing on the monitor, starting CPR and defibrillating, without setting up a high-fidelity simulator. When your training needs pacing, synchronised cardioversion, auscultation, 12-lead ECG or test results, consider the full version.

Is it a one-time purchase? Are updates paid?

No annual fees with the one-time purchase. A monthly plan is also available. Future updates are included at no extra cost.

When would I use the monthly plan? Can I cancel?

It is for people who run simulation training only a few times a year. You get every feature of the full version, one month at a time. It renews automatically until you cancel, and you can cancel at any time in Settings on your iPhone or iPad; you are not charged after that. The app also reminds you. If you teach regularly, the one-time purchase costs less.

Can I use it for ACLS, ALS / ILS or other courses, not just NCLS?

Yes. Rhythm checks, defibrillation, synchronised cardioversion and transcutaneous pacing are all available. It works just as well for physical assessment practice (auscultation, pupils), new graduate training, or any setting where you want to show a monitor.

Can it measure compression depth or rate?

No. If you need to measure skills, consider a high-fidelity simulator with sensors. Code Blue Monitor focuses on the monitor display and changing vital signs.

Won’t learners see the answer?

The rhythm name is not shown on the monitor, and the pacing capture threshold is normally hidden. Each value can be hidden individually, so you can set it up without giving anything away.

How is it different from a high-fidelity simulator?

It is not a replacement. It fills the gap between “not worth setting up the big equipment” and “narration alone is not enough”. It cannot measure compression depth or ventilation.

Descriptions of verbal simulation and high-fidelity simulators show general tendencies and vary by product and setup. Please check each product’s specifications before purchasing.

Does it follow AHA, ERC or Resuscitation Council guidelines?

Code Blue Monitor is a simulator, not a course. Rhythms, energy settings and the AED flow are built for the ACLS/ALS-style scenarios used in AHA, ERC, Resuscitation Council UK and ANZCOR courses, but the app is not endorsed by any of these organisations. Follow the current algorithm of the course you teach.

Is there an Android version?

Not yet. Code Blue Monitor runs on iPad and iPhone (iPadOS / iOS 15 or later).

Can we try every feature before buying?

Yes. The free app includes core features and one full chart case. For every feature, start the monthly plan and cancel when you are done, or ask us for an evaluation code that unlocks every feature for one month — useful before budgeting or procurement.
