O2 etank at 3 lpm how long will it last
Multiple studies have evaluated use of concentrators in low- and middle income countries (LMIC) and shown them to be cost-effective compared to cylinders. Oxygen concentrators are a common alternative to cylinders that, with reliable electricity, can produce oxygen onsite continuously, alleviating the transport and supply issues common with cylinders. Leaks have been observed at connection points, leading to significant wastage. However, they do require a system linking the oxygen production plant to the health facility to enable refilling, the reliability of which may be challenging due to poor road conditions, transportation costs, and stock management issues in low-income settings. Ĭompressed gas cylinders are a common standalone system that do not require electricity to supply oxygen. Many health facilities lack or are unable to maintain reliable access to oxygen and related supplies. Oxygen is an essential therapy to treat hypoxemia, but remains under-utilized in many low-resource settings due in part to cost and implementation challenges.

An estimated 120 million cases of childhood pneumonia, 14 million of which are severe, occur each year. Globally, lower respiratory tract infections, including pneumonia, are a leading cause of mortality in children, accounting for over 700,000 deaths in children under age 5 in 2015. The specific roles of these authors are articulated in the ‘author contributions’ section.Ĭompeting interests: The commercial affiliation with The Global Good Fund I, LLC ( does not alter the authors' adherence to PLOS ONE policies on sharing data and materials.

Over the trial period, 1284 power failure episodes with a mean duration of 3.1 minutes (range 0.08 to 1720 minutes) were recorded. The flow rate of the unit was adjusted once per week between 0.5 and 5 liters per minute. The trial was carried out at Jinja Regional Referral Hospital over a 75-day period. A prototype was built and tested in a non-clinical trial in Jinja, Uganda.

In this study, we examined the use of a novel, low-pressure oxygen storage system to capture excess oxygen from a concentrator to be delivered to patients during an outage. Often cylinders are employed to provide continuous coverage, but these can present other logistical challenges. The use of oxygen concentrators is common, but their effectiveness in delivering uninterrupted oxygen is gated by reliability of the power grid. Access to therapeutic oxygen remains a challenge in the effort to reduce pneumonia mortality among children in low- and middle-income countries.
