About

Code Blue Monitor turns an iPad into a patient monitor and defibrillator for emergency response training, with an iPhone as the instructor's remote. Change the rhythm and vital signs from your hand, and the monitor in front of the learners changes — so they notice the deterioration themselves instead of being told. Made by the instructors of NCLS, a resuscitation course for nurses in Japan, and used in every course we run. WHAT IT DOES - 35 ECG rhythms: sinus, atrial, ventricular, arrest rhythms, every AV block, ST changes, hyperkalemia, paced rhythm - Heart rate measured from the R–R interval, so Wenckebach and bigeminy behave like the real thing - Defibrillator with energy dial, charge, shock, synchronised cardioversion and transcutaneous pacing with capture - Vital signs — HR, NIBP, SpO₂, respiratory rate, EtCO₂, temperature, arterial line — controlled with sliders - Nothing shows until the sensor is attached or the measurement is taken - Hide any value individually for physical assessment practice - 12-lead ECG reconstructed from the current rhythm, with selectable infarct location - 23 blood gas cases, 4 chest X-rays, 3 echo clips, and a patient chart - Breath sounds (6) and heart sounds (6) that follow the ECG — irregular in AF, silent when there is no pulse - Pupil examination with a working light reflex - Chest compression fraction and an event log for debriefing - Ambient sounds: siren, in-hospital emergency call, Code Blue announcement TWO DEVICES, NO NETWORK The iPad (monitor) and iPhone (remote) connect directly to each other. No Wi-Fi router, no internet, no account. Enter the same 4-digit room code on both and you are ready. Everything also works on a single device. FREE VERSION Four rhythms (sinus rhythm, VF, pulseless VT, asystole), defibrillation with up to two shocks per scenario, vital sign control, the iPhone remote and the learner view. Enough to run a BLS session. FULL VERSION A single in-app purchase unlocks everything. No subscription, no per-device licence, free updates. WHO IT IS FOR Nursing schools and universities, hospital education departments, ACLS / BLS instructors, rapid response training, OSCE stations, simulation centres. Works with any manikin you already have. This app is a simulator for education and training only. It is not a medical device and must not be used for patient monitoring, diagnosis or treatment. All waveforms and values are simulated. More: codeblue.co.jp/monitor/en/ Sold as "NCLS Monitor" in Japan.

What's New in Code Blue Monitor

1.91

September 9, 2026

■ New ・28 patient-chart cases (shared with our SIM-Chart simulated EHR). Advance the phase and learners receive the records and results up to that point. ・Add your own images to the imaging list — your hospital's X-rays or self-made results, with findings. ・Alarm limits can now be set. Tap a value tile to open the settings. Respiratory-rate alarm added. ・Scenario presets now also set a matching blood gas (26 cases). ・A pulse on/off toggle on the bottom bar of the remote. Palpating when there is no pulse now shows a notice. ■ Improvements ・EtCO₂ can be set during cardiac arrest; if left alone it drops to 6 mmHg. ・The arterial pressure during CPR can now be set by the instructor; if left alone it shows 62/16 mmHg. ・S1 and S2 heart sounds are easier to tell apart. ■ Fixes ・Fixed the top buttons being hidden behind the status bar when using an iPhone as the monitor in portrait. ・Fixed some leads appearing nearly flat on the 12-lead during VF and torsades. ・Fixed the 12-lead automated interpretation not showing findings for the shark-fin ST elevation rhythm.
