How It Works

How It Works

CAIRE’s innovative technology gives COPD patients and their caregivers the confidence to breathe easier with the most advanced oxygen concentrators on the market.

Pulse Flow

The pulse flow setting of your oxygen concentrator delivers a “bolus”, or breath of oxygen, to your lungs with every inhale. CAIRE’s pulse flow technology is one of the most sensitive on the market, delivering the precise amount of oxygen you need when you need it most.

UltraSense technology

With a sensitive pulse dose trigger—UltraSense technology—this device ensures a pulse of oxygen is delivered quickly in the early stages of the breath and helps to reduce the risk of skipped breaths.


**Filters, tubing, cannulas available, please call for pricing**
