15 multi-scalar neonatal emergency spotters simulating critical bedside neonatal ICU events, loop anomalies, and rapid rescue protocols.

Practical Clinical Pearls & Bedside Rules

Spotter Protocol: Observe chest wall movement, transilluminate if desaturated, check pre/post-ductal saturations, and verify ET tube depth marking.

Clinical Diagnostic Case Spotters

Clinical Presentation: A 26-week ELBW infant on HFOV suddenly desaturates to 62% with heart rate 85 bpm. Chest wiggle is completely absent on the left hemithorax. Transillumination of the left chest shows a bright halo.
Ventilator / Diagnostic Finding: Absent Unilateral Chest Wiggle on HFOV + Bright Transillumination + Bradycardia
Definitive Diagnosis: Tension Pneumothorax on High-Frequency Ventilation
Immediate Bedside Action: Immediately reduce MAP, perform needle thoracostomy in 2nd intercostal space mid-clavicular line, and place 8-10 Fr chest tube.

Clinical Presentation: A 3-day-old preterm infant on PC-VG (target Vt 4.5 mL/kg) has PIP rising from baseline 14 cmH2O to set Pmax 28 cmH2O. Delivered Vt drops to 2.2 mL/kg. Flow-time curve shows blunted inspiratory spike.
Ventilator / Diagnostic Finding: PIP Hitting Maximum Pressure Limit + Halved Delivered Volume in VG
Definitive Diagnosis: Endotracheal Tube Kinking or Mucus Occlusion
Immediate Bedside Action: Suction ETT immediately with appropriate size catheter; if unable to pass catheter, replace endotracheal tube immediately.

Clinical Presentation: A term infant with meconium aspiration syndrome on conventional ventilation has pre-ductal SpO2 96% on right hand and post-ductal SpO2 78% on left foot on FiO2 1.0.
Ventilator / Diagnostic Finding: Significant Pre- vs Post-Ductal SpO2 Gradient (>15%) + Severe Hypoxemia
Definitive Diagnosis: Persistent Pulmonary Hypertension of the Newborn (PPHN) with Ductal R-to-L Shunt
Immediate Bedside Action: Initiate Inhaled Nitric Oxide (iNO) at 20 ppm, ensure adequate systemic blood pressure with inotropes, and target pre-ductal SpO2 91-95%.

Always evaluate patient synchrony and physiological response before changing ventilator parameters.
Maintain lung-protective strategies to minimize driving pressure ($\Delta P$) and mechanical power.
Continuously reassess liberation and extubation readiness on daily morning rounds.
