Self-inflating resuscitation devices (SIRs) for infant ventilation have drawbacks. A new volume-controlled device (VCD) showed improved CO2 levels and lower airway pressure in a cat model, warranting human trials.

Area of Science:

  • Neonatal and infant respiratory care
  • Medical device engineering
  • Pediatric resuscitation

Background:

  • Self-inflating resuscitation devices (SIRs) are standard for manual ventilation in neonates and infants.
  • SIRs present challenges including hyperventilation and inconsistent pop-off valve pressures, risking pulmonary barotrauma.

Purpose of the Study:

  • To evaluate a prototype volume-controlled device (VCD) as an alternative to SIRs.
  • To compare the VCD's performance against SIRs in a preclinical model.

Main Methods:

  • A prototype volume-controlled device (VCD) was developed.
  • Ventilation was performed in a cat model by blinded healthcare professionals familiar with SIRs.
  • Arterial and end-tidal CO2 levels, and mean airway pressure were measured.

Main Results:

  • Ventilation with the VCD resulted in arterial and end-tidal CO2 values closer to physiologic norms.
  • The VCD maintained a lower mean airway pressure compared to SIRs.
  • The VCD demonstrated more consistent ventilation parameters.

Conclusions:

  • The prototype volume-controlled device (VCD) offers potential advantages over traditional self-inflating resuscitation devices (SIRs).
  • The VCD achieved better physiological CO2 control and reduced airway pressure in a preclinical model.
  • Further human trials of the VCD for manual infant ventilation are recommended.
