Abstract
A therapeutic gas is administered to a patient. A sample gas is drawn from the therapeutic gas supply, and passed through a water-permeable tubular membrane. Concurrently, a section of the water permeable tubular membrane is maintained as a ventilated water permeable tubular membrane, by exposing outer surfaces of the ventilated water permeable tubular membrane to an ambient air flow. The ambient air flow may in some examples be moved over the tubular membrane via forced air such as for example via a fan associated with a housing surrounding the tubular membrane.
