The simulator models realistic newborn physiology — heart rate, oxygen saturation, temperature, and lung mechanics all respond dynamically to your interventions. There is no script: the baby responds to what you do, and to what you fail to do. MODES Tutor — guided coaching with real-time feedback on common errors like inadequate ventilation rate, inappropriate FiO2, slow compression rate, inadequate thermal control Practice — unguided free practice with full equipment access. Develop fluency and muscle memory and get comprehensive debrief with score. Challenge — a random scenario scored against a checklist covering seven domains: preparation, ventilation, circulatory support, de-escalation, oxygen management and thermoregulation SCENARIOS Term scenarios span mild, moderate, and severe birth asphyxia, antepartum haemorrhage, pneumothorax, sepsis. Preterm scenarios cover infants from 24 to 34 weeks gestation, with lung mechanics and resuscitation thresholds adjusted for gestational age. The manikin proportions scale continuously across the full 24-42 week range. Each scenario generates a unique patient with randomised starting parameters. Sim Builder lets you design, test, play and share your own custom sims: you set GA and weight, antenatal history, lung disease, starting vitals, cord lactate, Hb and more. You can pre-set a range of initial PIP and PEEP and Flow and FiO2 settings to teach careful equipment set up pre-birth. EQUIPMENT Mask ventilation with real-time manometer (PIP and PEEP), endotracheal intubation, umbilical venous catheter with animated insertion, adrenaline and fluid bolus administration, needle decompression for tension pneumothorax, surfactant, supplemental oxygen with blender control (FiO2 21-100%), overhead heater, plastic wrap, and hat. SCORING Full post-simulation debrief with breakdown across multiple domains. Category scores highlight specific gaps. neoSim is informed by NRP and ANZCOR neonatal resuscitation guidelines. It is an educational tool intended to supplement, not replace, formal training and clinical supervision. neoSim is not a medical device and must not be used for clinical decision-making or patient care. ## Key features - Realistic newborn physiology simulation - Tutor mode with real-time feedback - Unguided practice with full equipment access - Challenge mode with scenario scoring - Custom scenario builder - Comprehensive post-simulation debriefing ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/neosim-by-nicutools/id6762543461/reviews.md ### 5/5 — Paeds reg review *2026-07-28* BPT 3 here- it’s been 2 years since my last neonates term and this app helps keep my resus skills up to date. I recently had a significant resus and having done the sims it prepared me incredibly well and we luckily had a good outcome which I credit to this app. ### 5/5 — Outstanding Simulation Tool *2026-05-12* This app is a much needed and incredible tool for anyone within the neonatal field, especially those developing or fleshing their neonatal resuscitation skills. Test your skills and knowledge and work to achieve best neonatal resuscitation outcomes. I love that each day is a different simulation and you can chose the type of neonatal condition you want to refresh yourself on. Great as an educational resource to engage clinicians. App works seamlessly and is such a fun time! Any and all hospitals would benefit having this in their education toolkit! ### 5/5 — Extremely impressed! Fun, educational neonatal resuscitation simulation. *2026-05-09* There are many different birthing scenarios in which you are required to resuscitate a newborn. All the equipment needed for a newborn resuscitation is there and you are required to provide respiratory or circulation support, with the app assessing your rates, achieved tital volume and oxygenation. You receive a score at the end of each scenario with very useful feedback on how to improve. This app is perfect for any Medical Officer or Nurse/Midwife wanting to practice their skills in neonatal resuscitation. I’ve never had so much fun doing professional development. ## Frequently asked questions about neoSim by Nicutools ### What is neoSim? neoSim is an interactive neonatal resuscitation simulator designed for medical students, nurses, midwives, and doctors.

Updates typically include new features, bug fixes, and guideline adherence. ## Version history (last 5 releases) ### 2.8.2 — 2026-08-24 SCORING The debrief now scores what the baby needed rather than what was attempted. An intervention that was indicated but not delivered counts against the score instead of being left out of it — previously, skipping something could score better than doing it imperfectly. Ventilation, chest compressions and adrenaline are treated as critical actions. Not delivering one when it was indicated caps the overall score, and the debrief states which action it was and the time it became indicated. Unnecessary adrenaline, compressions, UVC insertion, intubation and needle decompression are now grouped as safety events rather than sitting among the checklist items. Earlier scores are unchanged and remain in the training log. Sim of the Day percentiles are compared within a scoring version, so earlier scores are not ranked against the new ones. SELF-INFLATING BAG Sims can now be authored with a self-inflating bag in place of a T-piece resuscitator. Inflations are delivered by squeezing the bag; rate, depth and inspiratory time reflect the squeeze. The pressure-relief valve is set at 35 cmH₂O and can be held shut where higher pressures are required. The bag delivers no PEEP. An oxygen reservoir can be fitted and removed during the sim. Reservoir fill is integrated from delivered flow and modulates delivered FiO₂ below the source gas. Delivered FiO₂ from the bag is derived from published bench measurements in neonatal self-inflating bags (Sasi et al., J Paediatr Child Health 2013). On 100% source gas without a reservoir it is approximately 75% at 1 L/min and plateaus near 94%; the commonly taught 40% is reached only at about 0.2 L/min (which cannot be delivered on the installed flow meter) Fixed bug where the chest did not move during bag inflations. Delivered tidal volume, scoring and the infant's response were correct throughout — only the chest movement was missing, so effective ventilation could read as ineffective. OXYGEN CYLINDER SUPPLY Gas supply is authored independently of the device, so either a T-piece or a bag may run on blended gas or on a cylinder. Where a cylinder is used there is no blender and flow rate is the only oxygen control: contents deplete with use, delivered flow tapers below 20 bar, and a spent cylinder can be exchanged mid-sim. TRANSILLUMINATION The cold light glow is smaller, brighter and less red, so it reads against well-perfused skin rather than only against a cyanosed chest. Saturated red is now reserved for the affected hemithorax under tension pneumothorax, widening the contrast between sides. Fixed bug where transillumination wand disappeared behind the chest. OTHER CHANGES - Laryngeal mask (i-gel) insertion is animated through the full placement sequence. - Subcostal recession intensity scales with central respiratory effort, not chest wall movement alone. - Reduced chest excursion for normal spontaneous breathing. - Solo sims no longer end early while a pneumothorax is being assessed with the cold light. - Shared sim links can be set to last up to six months and have no limit on the number of plays. An expired link now names the sim and who sent it. ### 2.8.1 — 2026-08-23 SELF-INFLATING BAG Sims can now be authored with a self-inflating bag in place of a T-piece resuscitator.

A new 3D chest • A true 3D torso replaces the flat manikin — lifelike chest rise, indrawing and colour change. • "Cold Light" transillumination now shines applied via a "wand" not your finger-tip for better visibility, with the affected side glowing red under a tension pneumothorax. Smarter thermoregulation • Plastic wrap now properly keeps preterm babies warm — and is offered for any baby under 1500 g. • Cold babies now show depressed breathing (apnoea when severe), reversing on rewarming. • Overheating now behaves realistically by gestation. ### 2.7.1 — 2026-07-29 • Meet the new 3D newborn — a fully three-dimensional chest that rises, retracts and changes colour in real time, so every breath, compression and intervention feels true to life. • Cold Light transillumination now uses a handheld wand — your finger no longer blocks the glow when localising a pneumothorax, with cleaner, more realistic light. • Tension pneumothorax — the affected side now shows subtle chest movement and indrawing instead of sitting frozen, recovering as you decompress. • Refined scoring for chest-compression response. • Stability and polish. ## More apps by Michael Hewson - [Nicutools](https://appshunter.io/ios/app/nicutools/id6784494609) All apps by Michael Hewson: https://appshunter.io/developer/1894611637 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
