How to Narrow It Down
- Pressure: Newtowne and Summit To Sea chambers run at 1.3 ATA. OXYREVO and Volaira portable chambers adjust up to 1.5 ATA, and the Volaira Freedom runs at 1.4 ATA. Your licensed medical provider should guide which pressure is right for you. Our 1.3 ATA vs. 1.5 ATA guide explains the equipment differences.
- Lying down or sitting up: Lay down chambers suit patients who want to lie back and rest during a session. Seated and reclining chambers such as the Newtowne Shoe, Summit To Sea Dive Vertical, OXYREVO Forward90 and Volaira Ascend are easier to get in and out of and let you read or work.
- Getting in and out: For patients who use a wheelchair, compare the Summit To Sea Grand Dive Pro Plus and the Volaira Freedom. The Newtowne Tent offers walk in entry with more than 56 inches of interior height.
- Shoulder room: If you are broad shouldered or tall, step up in diameter. The 34" and 40" Newtowne, the Summit To Sea Dive and Grand Dive, and the OXYREVO Apex36 all add room over the most compact models.
- More than one person: The Summit To Sea Grand Dive and Grand Dive Pro fit 2 to 3 people, which works well for a parent and child.
- Frame style: Internal frames (OXYREVO and Volaira) give a cleaner look. External frames (Newtowne and most Summit To Sea models) are a traditional, value focused design.
