BALL GROUND, Ga. - CAIRE’s FreeStyle Comfort portable oxygen concentrator with proprietary autoSAT technology is now available in the United States. The autoSAT technology adjusts oxygen delivery to deliver a consistent volume of oxygen with the patient’s breath rate during activity or at rest. “Today’s announcement is a major step forward in serving today’s oxygen therapy users with the technology they need to support a more active lifestyle and better quality of life,” said Ken Hosako, president and CEO of CAIRE Inc. “Instead of the respiratory patient having to adapt to their portable oxygen device, this device adapts to them through our patented technology.” Last month, the FreeStyle Comfort with autoSAT was prominently featured in a study by Georgia State University published in the journal Pulmonary Therapy. The bench study compared FiO₂ delivery from POCs, wall oxygen and a standalone concentrator (CAIRE Companion 5) using a respiratory failure-specific lung simulator replicating an adult with chronic respiratory disease at 15-40 breaths/min. Among the POCs tested, the FreeStyle Comfort, with or without autoSAT, consistently achieved the highest or equivalent FiO2 at elevated breathing rates (30-40 bpm). However, at lower rates (15-20 bpm), results varied by device. The study was funded by CAIRE but was independently conducted and analyzed at Georgia State University.
