The Nuvo lite provides oxygen to patients that require Long Term Oxygen Therapy (LTOT) in the comfort of their home. Nuvo lite is a compact and light stationary oxygen concentrator, that uses standard PSA technology that provides constant oxygen flow of oxygen up to 5 litres per minute. The Nuvo lite oxygen concentrator draws in room air, separates the oxygen from other gases in the air and delivers the oxygen at high concentrations to the patient. The Nuvo lite has an integrated oxygen sensing device for monitoring oxygen levels, and a ?No-Flow? alarm to alert the patient if there is no supply of oxygen to the patient.
