![]() ![]() For patients who live active lives and are often away from an AC (wall socket) power source, a portable oxygen concentrator is the best choice. Portable oxygen concentrators offer smaller size and less weight as well as greater flexibility with power sources. Stationary oxygen concentrators have higher oxygen output and lower costs. The key differences between stationary and portable concentrators can be summarised by four major factors: 1) oxygen output, 2) size and weight, 3) power options and 4) price. ![]() ![]() min −1 and battery life, as well as other specifications.Portable concentrators vary in weight, size, oxygen flow settings, range of L Portable oxygen concentrators are the latest technology for LTOT users who desire a small, lightweight and portable oxygen solution in a compact and mobile unit ( figure 1b). They currently support oxygen flow rates up to 2 L they can be easily moved from one room to the other or they can be transported by car for travel). from a cigarette lighter socket) and are mobile ( e.g. from a wall socket) and direct current (DC e.g. These units run on both alternating current (AC e.g. b) Portable oxygen concentrator.Ī relatively new option is a super small home concentrator, which can weigh approximately 4.5 kg. In this review, we will present different oxygen devices and delivery systems.Ī) Stationary oxygen concentrator. There is a large variety of available oxygen-conserving devices and, considering the high costs of LTOT and the impact on patients' health-related quality of life, optimal device selection and prescribing requires a clear understanding of these devices. Nowadays, LTOT use is higher in women, and this is projected to increase further in the near future due to the high number of middle-aged female smokers . The following three groups of patients with chronic hypoxaemic lung diseases are suitable for long-term oxygen therapy (LTOT) :ġ) Patients with arterial oxygen tension ( P aO 2) ≤55 mmHg at rest in nonrecumbent position, despite optimal treatment of underlying condition.Ģ) Patients with P aO 2 >55 mmHg associated with evidence of central nervous system dysfunction, cor pulmonale, secondary pulmonary hypertension or polycythaemia.ģ) Patients with demonstrable fall in P aO 2 below 55 mmHg and desaturation during sleep and/or exercise. The Nocturnal Oxygen Trial and a study published by the British Medical Research Council are the landmark studies that have consolidated evidence for domiciliary oxygen use. Oxygen use has extended from inpatient to outpatient settings for patients with chronic pulmonary diseases and complications of hypoxaemia. ![]()
