Revolutionizing Portable Oxygen Therapy

Zen-O and Zen-O-Lite Review

Learn More about RRT Therapy and how the Ohio Medical line of GCE portable concentrators can enhance your patient compliance.

Rate Responsive Therapy™ keeps patients saturated — automatically.

Some portable concentrators deliver a fixed volume of oxygen per minute, so the bolus shrinks and FiO₂ drops as a patient breathes faster — forcing the patient to turn the setting up. GCE's Rate Responsive Therapy delivers a constant bolus and automatically responds to the patient's breath rate, so oxygen delivery actually increases with activity instead of decreasing.

Delivers a constant bolus regardless of breath rate.
Automatically increases oxygen as the patient's demand rises.
Keeps patients saturated even at high breath rates.
No need to change device settings before activity.
Up to 44% more oxygen than some devices at 25 BPM.
