Air Oxygen Blender

An Air & Oxygen Blender is a Class II medical device that precisely mixes compressed medical air and oxygen to deliver controlled fractions of inspired oxygen (FiO2 21-100%) to patients requiring respiratory support. Essential in neonatal, pediatric, and adult critical care, these devices ensure accurate oxygen delivery via ventilators, CPAP systems, oxygen hoods, incubators, and transport systems. Operating at 40-60 psi inlet pressure, they maintain set FiO2 within ±2-5% accuracy across varying flow demands (0-120 L/min). Gas-specific DISS or NIST fittings prevent dangerous cross-connection between oxygen and air supplies. Available in wall-mounted, rail-mounted, portable, and ventilator-integrated configurations. Primary clinical applications include neonatal intensive care (oxygen hoods, incubators, nasal CPAP), pediatric and adult mechanical ventilation, non-invasive ventilation, and critical care transport. Critical safety requirements include verification of correct gas connections, regular calibration, leak testing, and immediate response to gas supply failure alarms. Indispensable for preventing both hypoxemia and oxygen toxicity (particularly retinopathy of prematurity in neonates) in patients requiring precise oxygen therapy.
