Flow meters control gas flow from ventilators and other medical gas devices. They have a scale for reading flow and a valve for adjusting flow.

Flow indicators check for air flow and detect carbon dioxide in exhaled breaths to verify proper placement of endotracheal tubes (ET). Also known as flow caps, they are single-use devices that attach to resuscitation bags, face masks, or ET tubes.

Adapters connect the fittings of medical gas flow meters to different types of oxygen supply connectors.

Flow diverters direct a small sample of gas to a flow sensor that measures volume flows from ventilators and other medical gas devices.
