10.3 (52)
2026-09-22
Same version as the previous 10.2 (48), but the pulse waveform has been adjusted to bring it closer to reality, spontaneous ectopic beats have been introduced, the heartbeat sound for ectopic beats has been adjusted, and the colors of Cockpit mode have been changed to improve readability.
HEMODYNAMICS
The model ties heart rate, stroke volume, cardiac output and resistances to the filling pressures and to the baroreflex.
Cardiac output and index, systemic and pulmonary resistances, wedge and pulmonary pressures, stroke volume, blood volume and ventricular work, with values colour-coded in every mode, except in the random case, where the colour-coding is switched off.
RECOVERY AND DEATH CRITERIA
They are now written down and in plain sight, in the panel and in the instructions, so you know what you are playing for.
To stabilise, eleven conditions must hold at once for five seconds: cause controlled, no arrhythmia, MAP 65-120, heart rate 50-115, cardiac index above 2.2, DO2 of 500, lactate below 3 and falling, wedge pressure under 18, CVP under 12, urine output above 35 mL/h and SpO2 above 92 percent. In sepsis, also the right antibiotic, source control and infection below 20 percent.
You lose with systolic blood pressure under 50 or over 220, heart rate under 35 or over 220, wedge pressure over 30, or CVP at zero with output collapsed. Ventricular fibrillation has its own 30-second countdown.
PATIENT VARIABILITY
Contractility, vascular tone, blood volume, reflex gain and sensitivity to each drug vary from patient to patient, chosen with the on-screen button. Turn it off from the "Patient" button if you prefer reproducible runs.
PULSE WAVEFORM AND SOUND
The pulse waveform has been adjusted to bring it closer to clinical reality, synchronised with the ECG trace on the same clock. Spontaneous ectopic beats have also been added in every game mode, with their own heartbeat sound for these cases - duller, with the two auscultation beats out of sync, the way a real extrasystole actually sounds on exam.
Sound volume button from 0 to 100 next to the clock, and an independent mute button in the trends panel that overrides it. Voices and alerts in all five languages.
MORE ARRHYTHMIAS, AND TIME TO TREAT THEM
A button to adjust how often arrhythmias appear in pathological modes, selectable from 0 to 30 percent or AUTO mode.
Dopamine above 20 mcg/kg/min triggers ectopic beats ten seconds after starting, which degenerate into ventricular tachycardia if you do not lower the dose.

New cockpit mode. A second interface styled like a flight deck: six analogue needle instruments, a multi-function display with switchable pages, a warning light panel, and infusion levers with continuous dosing instead of fixed doses.
The classic interface is still there. After updating, the game starts as it always did. Cockpit mode is optional and is switched on from the pill at the bottom left, or from the selector in the cockpit itself. Your choice is remembered.
Tests you have to order. Blood gas, lactate, blood count, echocardiogram and Swan-Ganz catheter. Each takes its time to come back, and the catheter unlocks the wedge pressure, cardiac output and resistance readings, which stay dark without it.
Lactate with inertia. It rises fast when things go wrong and falls slowly when they are put right, so normalising the numbers is not enough.
Ventricular fibrillation is now visible on the electrocardiogram trace, with an on-screen warning.
Outcome panel at the end of the game, with the round score and the cumulative total.
Internal adjustments to how the patient behaves and to the antibiotic options, so they respond more coherently.
Five languages: Spanish, English, German, Chinese and Japanese.

Japanese language support has been added for both voice and text. This version is the same as the previous one. No other changes have been made.

2025-12-03
The logic of diagnostic and therapeutic modes has been updated to make it more consistent with real physiology.
A distinction has been added between the right and left circulations:
• The right side is now separated from the left side to increase realism. Pressures are now calculated in a backward direction, from the left ventricle toward the right side, which reflects how congestion usually develops in heart failure.
• New variable: PVR (Pulmonary Vascular Resistance). Similar to SVR in the systemic circuit, a simplified PVR has been introduced.
• PCP (Pulmonary Capillary Pressure or Wedge) is now calculated based on blood volume and left ventricular function.
• PAP (Pulmonary Arterial Pressure) has been updated. PAP is now the sum of the pressure ahead (PCP) plus the resistance of the lungs.
• PVC (Central Venous Pressure) calculation has been revised. PVC now depends on total blood volume and how easily blood can enter the pulmonary artery through PAP.
These changes allow the simulator to show high PCP with normal PVC, enabling the diagnosis of pure left sided failure. This requires specific vasodilator and diuretic therapy instead of treating it as global volume overload. It also allows untreated left sided failure to evolve into right sided failure, as PVC starts to rise minutes later.

A new version of SimShock has been implemented with significant technical and physiological updates:
* Simultaneous Therapies: The simulation engine has been refactored to allow for simultaneous therapy administration. It is now possible to combine the effects of multiple drugs (e.g., Saline, Dopamine, Noradrenaline, Dobutamine, Nitroglycerin) at the same time, resulting in a more complex and realistic hemodynamic simulation.
* Physiological Tuning (Furosemide): A hemodynamic response adjustment has been implemented. Specifically, the logic for Furosemide (Seguril) has been modified from a continuous infusion to a 30-second bolus, and its potency has been adjusted. This prevents an abrupt drop in volemia and stabilizes the heart rate response, resulting in more physiological behavior.
* Quick Reset Function: A hidden reset function has been added. Tapping the heart icon on the main screen will reset the simulation to its initial state.

New Modes in SimShock
This update adds two game modes designed to make training more intense:
• Free Mode
Play without limits by selecting the initial condition: Heart Failure, Hemorrhage, Septic Shock, or Random (starts the game with any of the previous ones).
Each game is scored based on the chosen difficulty and the time used:
–10 points if the patient dies
+1 to +10 points if you cure the patient depending on the time invested
All scores are added together to obtain an accumulated total
• Exam Mode
Designed to compete against yourself. It consists of 10 randomly generated games played continuously.
In this mode, end screens for cure or death are disabled: when one game finishes, the next starts immediately with a beep.
The ICU button is inactive and you rely only on your decisions.
To end the exam early, press the Exam button again or the Reset button to return to Free Mode.

Interface Correction on the Monitor: A design issue on the vital signs monitor has been resolved. The "Therapeutic Modes" buttons were partially hidden at the bottom of the screen on some devices. They have been repositioned to ensure full visibility and accessibility.
Improved Transfusion Simulation: A functional error where the patient's blood volume did not update during a transfusion has been corrected. Now, the volume increases realistically in real-time, improving the simulation's accuracy.
Enhanced Visual Feedback: The graphical representation of the blood transfusion has been improved. The bag's tubing is now visually shown filled with blood (red color) when the transfusion is active, providing a clear indication of the process.
Increased Visual Clarity: The definition and contrast of the colors and text on the main control panel have been enhanced. This change increases readability and facilitates faster and safer interaction.
Complete Fix of the Pause Function: The "Pause" function has been improved. Previously, when pausing the simulation, some animations and processes continued to run. Now, pressing pause completely stops all in-game activity, ensuring a total and consistent interruption.

2025-07-25
This update introduces significant improvements to the hemodynamic simulation engine of SimShockPad, as well as new visual features for a more immersive and educational experience. The key changes are as follows:
Deep Overhaul of the Hemodynamic Simulation Engine:
Realistic Fluid Response: The response to fluid infusion (saline solution) has been completely redesigned. Now, the Central Venous Pressure (CVP) responds dynamically and gradually. This prevents unrealistic behaviors (such as sudden drops or spikes) and ensures that the CVP rises naturally as the patient's volume is restored, resolving previous instabilities.
Implementation of Myocardial Depression: To increase realism and clinical challenge, a new "cardiac fatigue" (myocardial depression) mechanic has been added following prolonged shock. This creates complex scenarios where fluid administration alone is not sufficient, requiring the use of inotropic drugs (such as Dobutamine) to restore heart function.
Improved Pathology Models: The Heart Failure model has been refined to more accurately simulate the decrease in cardiac contractility, making it more faithful to real pathophysiology.
Visual and Interface Enhancements:
Defibrillator Paddle Animation: When applying an electrical shock, an animation of the defibrillator paddles on the patient is now displayed. This provides clear and immediate visual feedback for this critical action, enhancing user immersion.
version 3.7
2025-07-23
Hello! In this update, we've improved the app to make it even easier for you to use.
- Automatic Language Detection: The app now detects your device's language and adjusts automatically (Spanish, English, or Mandarin Chinese).
- If your device is set to a language other than Spanish, English, or Chinese, the app will default to English to ensure you can continue to use it without issues.
We hope you enjoy this improvement!
