The Smart Nasal Cannula is a disposable nasal cannula with the worlds’ first “in-line” flow meter the “Oxyview”. The most unique feature of the Oxyview oxygen flow meter, other than its increased accuracy and assurance that it brings to home oxygen therapy, is the fact that it works in any position, hands-free. This device provides a visual aid to monitor oxygen flow through oxygen tubing and is located below the cannula nearest the patient where oxygen flow matters the most. Oxyview is made of strong medical grade carbon and is resistant to moisture, temperature and altitude; providing a great way for patients, pilots and caregivers to quickly verify proper oxygen flow. Oxygen cannot be seen and is a clear odorless gas. Without Oxyview, it would be like driving your automobile without an instrument panel to verify functionality and operation. We see Oxyview becoming the gold-standard of oxygen monitoring devices.
