Vapotherm Oxygen Assist Module
Closed-loop FiO₂ controller for Precision Flow – automated SpO₂ targeting via a PID algorithm, with published neonatal data showing substantially increased time within the target SpO₂ range compared with manual control.
Manual FiO₂ titration in preterm neonates leaves infants outside their prescribed SpO₂ range a substantial portion of the monitored time, despite the documented consequences of both hyperoxia and hypoxia. The OAM attaches to the existing Precision Flow platform and runs a PID controller that compares live SpO₂ to a clinician-defined target and adjusts FiO₂ on a short response interval, learning from intra-session SpO₂ patterns to anticipate predictable desaturations. Published neonatal studies report substantially increased time within target SpO₂ range under closed-loop FiO₂ control versus manual titration.
- Substantially increased time in target SpO₂ range – Published neonatal data show meaningful improvement vs manual FiO₂ control.
- Anticipatory PID algorithm – Learns from intra-session SpO₂ patterns and adjusts forward, not only reactively.
- Short response interval – Adjustments occur far more frequently than realistic manual titration.
- Clinician-defined target and bounds – Operates only within prescribed SpO₂ limits; clinical governance preserved.
- Accommodates lower SpO₂ targets where clinically appropriate – Supports oxygen-targeting strategies in chronic lung disease.
- Add-on module – attaches to existing Precision Flow units; no new platform required.
- Compatible with Masimo SET and Nellcor OxiMax oximetry.
- Adjusts FiO₂ only – leaves flow and temperature under clinician control.
Used in preterm neonates on Precision Flow Hi-VNI Technology where continuous SpO₂ targeting within a defined range is clinically important. Enables automated FiO₂ titration to a clinician-set target without removing flow or ventilation decisions from the clinician.
