Visle is a clinical emergency simulator for doctors, interns and medical students. You manage a patient in real time: take the history, examine, order investigations, choose drugs and type the doses yourself. The patient’s physiology responds to every decision. Afterwards, a detailed debrief shows where your management matched current guidelines and where it did not.
Our mission
To help the medical community practise the decisions that matter most, safely, before they face them on a real patient. We want every clinician to be able to test their own methodology and knowledge against a patient who reacts, and to see honestly where they stand. India first, then the world.
Why Visle exists
Most of us learn emergency management from textbooks, ward rounds and a few frightening nights in casualty. Textbooks do not push back. Real patients cannot wait while we learn. There has been no safe place to make a mistake, watch its consequence unfold, understand why, and try again.
Visle is that place. A missed history detail, a nitrate given at the wrong time, a morphine dose that is too generous or a delay in reperfusion all play out on the monitor, exactly as they would at the bedside.
How it works
- A patient who responds in real time. Heart rate, blood pressure, SpO₂, respiration, the ECG and the patient’s own words change minute by minute.
- Free dosing. Type any dose. Underdoses, overdoses and contraindicated drugs behave the way they would in a real patient.
- Traps you only find by doing it properly. Some details surface only if you take a complete history, just as in real life.
- Learning mode and Exam mode. Get feedback after every drug, or work blind and see everything in the debrief.
- A guideline-based debrief. A protocol checklist, every drug you gave with a verdict and the reason, a timeline of the vitals and a model management plan.
Who it is for
- MBBS students preparing for clinical postings and exams
- Interns and residents who want to rehearse emergencies before their next casualty duty
- Emergency, ICU and medicine teams running practice sessions
- Nurses and paramedics working in acute care
- Medical colleges and educators who want structured, repeatable assessment
Our clinical standards
Every case is written against current major guidelines, such as the ACC/AHA and ESC guidance for STEMI, and adapted to the realities of Indian emergency departments. Doses, timings and decision points are referenced, and cases are reviewed when guidelines change. If you find an error, we want to know. Each case shows its reference basis, content version and review status under “Case information and references”. Read our Clinical content policy to see how cases are written and corrected.
What is coming next
Case 01, an anterior STEMI, is live. Next in the library are the emergencies clinicians meet every week in Indian hospitals: organophosphate poisoning, neurotoxic snake bite, diabetic ketoacidosis, anaphylaxis, acute severe asthma, septic shock and eclampsia.
