rest of the patients may get but scant nursing attention and are generally disturbed by the noise of machines and the frequent visits of doctors. A great deal of space is required around the bedside to allow for bulky respirators, suction apparatus, oxygen cylinders, E.C.G. oscilloscopes, etc., and usually at least two bed spaces are occupied. Since piped oxygen and suction are not universally ...

It is known that 50% N20 and 50% 02 mixture is a safe and efficient analgesic for parturient women. The British Oxygen Company have produced single cylinders of premixed gases containing a 50/50 gas and oxygen mixture, which would be ideal for use in midwifery if they could be relied upon to dispense a constant 50/50 mixture. Composition changes in premixed gas and oxygen mixtures have been rep...

Mass casualty events and disasters, both natural and human-generated, occur frequently around the world and can generate scores of injured or ill victims in need of resources. Of the available medical supplies, oxygen remains the critical consumable resource in disaster management. Strategic management of oxygen supplies in disaster scenarios remains a priority. Hospitals have large supplies of...

BACKGROUND Pneumonia is a leading cause of childhood mortality globally. Oxygen therapy improves survival in children with pneumonia, yet its availability remains limited in many resource-constrained settings where most deaths occur. Solar-powered oxygen delivery could be a sustainable method to improve oxygen delivery in remote areas with restricted access to a supply chain of compressed oxyge...

Mass casualty and pandemic events pose a substantial challenge to the resources available in our current health care system. The ability to provide adequate oxygen therapy is one of the systems that could be out-stripped in certain conditions. Natural disasters can disrupt manufacturing or delivery, and pandemic events can increase consumption beyond the available supply. Patients may require m...

Ambulatory oxygen therapy in patients with COPD and exercise hypoxaemia may improve exercise capacity and breathlessness. The improvement in exercise tolerance is related to the degree of exercise hypoxaemia. As effects from ambulatory oxygen therapy are prone to placebo effects, careful patient selection is required, with formal assessment. For effective ambulatory oxygen delivery, oxygen shou...

The erosion of highly-ordered pyrolytic graphite (HOPG) caused by exposure to hyperthermal atomic oe p) atoms was explored. Profilometry has revealed that the overall erosion yield is linear with respect to increasing atomic oxygen exposure at a constant sample temperature of 373 K. Atomic force microscopy (AFM) was employed to image the eroded material that contains numerous nanoscale to micro...

Field anesthesia machines (FAM) with gas-powered ventilators have been developed for remote locations that may not have a central supply of oxygen. These ventilators may rapidly deplete oxygen cylinders, especially in patients with decreased pulmonary compliance. Our goal in this study was to determine oxygen consumption rates with a contemporary FAM in models of high (HC) and low (LC) pulmonar...

Refilling USAID oxygen cylinders, indigenous solution to a foreign challenge - IJCA- Print ISSN No: 2394-4781 Online No:- 2394-4994 Article DOI 10.18231/j.ijca.2022.053, Indian Journal of Clinical Anaesthesia-Indian J Clin Anaesth

We studied the evolution of elliptic heavy SF6 gas cylinder surrounded by air when accelerated by a planar Mach 1.25 shock. A multiple dynamics imaging technology has been used to obtain one image of the experimental initial conditions and five images of the time evolution of elliptic cylinder. We compared the width and height of the circular and two kinds of elliptic gas cylinders and analyzed...
