Circuits & Hyperinflation Bags

Our hyperinflation bags and breathing circuits are stocked in the pressure-limited, color-coded manometer configurations NICU and respiratory therapy teams rely on for safe lung recruitment. Pair single- and multi-liter hyperinflation systems with matched circuits and connectors from brands like Ambu, Sun Med, and Mercury Medical. Great Oak Medical keeps these time-sensitive respiratory essentials moving fast, because a NICU can't wait on backorders.
