MACS critical care CPAP for EMS ground / air transport and Hospital use
MACS is an easy-to-use, economical mask CPAP (Continuous Positive Airway Pressure) system. Its demand flow system delivers CPAP without wasting oxygen. A calibrated knob sets the CPAP level and a switch selects 65% or 100% oxygen. Your per run cost is less due to lower oxygen costs and affordable patient circuits.

MACS is designed for patient application by mask or endotracheal tube. Indications include: congestive heart failure (CHF), asthma, acute respiratory failure (ARF), trauma, COPD, near drowning or any patient with severe breathing difficulty. MACS supports patients in respiratory distress who would otherwise require intubation.

EMS agencies with mask CPAP protocols have reported a substantial decrease in patient intubations with increased ER stabilization.


The MACS CPAP System is a critical care device designed for use by healthcare professionals under the direction of a physician.
