Oxygen Consumption & Cost Calculations
How can I connect an oxygen cylinder to a device that needs low pressure (e.g. nasal cannula or facemask)?
Low pressure outlets are most commonly attached to, and driven by, a flowmeter attached to a pressure regulator as shown, these types of outlets are simple push fit and similar to the outlets on oxygen concentrators (e.g. use smooth bore oxygen tubing)
