This interim guidance on oxygen sources and distribution strategies for COVID-19 treatment has been adapted from WHO and UNICEF’s technical specifications and guidance for oxygen therapy devices, which is part of the WHO medical device technical series. This guidance is intended for ...health facility administrators, clinical decision-makers, procurement officers, planning officers, biomedical engineers, infrastructure engineers and policy-makers. It describes how to quantify oxygen demand, identify oxygen sources that are available, and select appropriate surge sources to best respond to COVID-19 patients’ needs, especially in low-and-middle income countries.

First published in 2020, this toolkit is intended for clinicians working in acute care, managing adult and paediatric patients with acute respiratory infection, including severe pneumonia, acute respiratory distress syndrome, sepsis and septic shock. The main objective is to provide key tools for us...e in the care of critically ill patients – from hospital entry to hospital discharge.
The 2022 updated version includes new tools and adapted algorithms, checklists, memory aids for COVID-19 and influenza, and the latest clinical evidence regarding clinical management of SARI. It is intended to help clinicians care for SARI patients: from epidemiology of severe acute respiratory infections, screening and triage, infection prevention and control, monitoring of patients, laboratory diagnosis, principles of oxygen therapy and different types of ventilation (invasive and non-invasive), as well as antimicrobial and immunomodulator therapies, to ethical and quality of care assessments.
The first edition is availbel in Ukrainian and Russian

Oxygen is an essential medicine required at all levels of the health care system; only high quality, medical-grade oxygen should be given to patients. Pressure swing adsorption (PSA) oxygen generating plants are a source of medical-grade oxygen. This document provides technical specifications as th...e minimum requirements that a PSA Oxygen Plant must meet for use for the administration of medical-grade oxygen.

Countries can use this tool to collect in-depth facility inventories of biomedical equipment re-allocation, procurement and planning for COVID-19 case management. The survey assesses quantified availability and the causes for non-functioning of different sources of oxygen delivery and supply systems... to the patient in order to determine priorities and re-allocation requirements in accordance with needs.

The WHO COVID-19 Essential Supplies Forecasting Tool (COVID-19-ESFT) is meant to help countries forecast essential supplies for their COVID-19 response including personal protective equipment (e.g., masks and gloves), biomedical equipment for case management (e.g., ventilators and oxygen concentrato...rs), diagnostic reagents and equipment, essential drugs for supportive care, and consumable medical supplies.
The tool is best suited for estimating essential supply needs over a short time period (12 weeks or fewer) but can be used for longer.
COVID-19-ESFT does not quantify or account for resources already available locally or those pending delivery. When using the ESFT to inform procurement, we recommend factoring in resources already available locally and only including the additional resources required in the forecast.
This tool is updated regularly so users should monitor the website for the latest release version.

This document describes the medical devices required for the clinical management of COVID-19, selected and prioritized according to the latest available evidence and interim guidelines. This includes: oxygen therapy, pulse oximeters, patient monitors, thermometers, infusion and suc...tion pumps, X-ray, ultrasound and CT scanners as well as personal protective equipment. In order to facilitate access to quality assured priority medical devices, the document also includes technical and performance characteristics, related standards, accessories and consumables. It is intended for policy-makers and planning officers in Ministries of Health, procurement and regulatory agencies, intergovernmental and international agencies as well as the medical device industry.
This document is an update to the List of priority medical devices for COVID-19 case management and Technical specifications for invasive and non-invasive ventilators for COVID-19.
This document complements the Technical specifications of personal protective equipment for COVID-19.

This poster is intended for health workers and other personnel on the safety and mitigation measures that need to be adhered to when dealing with medical oxygen. Medical oxygen, either in liquid or gas form, is an oxidizing agent that can result in a fire or explosion if not handled properly.
In the face of rapid increases in the number of hospitalizations due to COVID-19 in Latin America and the Caribbean, coupled with shortages of human and material resources, including medical equipment and gases, there is a need to redesign models of care in the Region to optimize available resources... and ensure that more patients receive the quantity and quality of oxygen they need. Oxygen is included in the World Health Organization’s list of essential medicines and is used to care for patients at all levels of integrated health services networks. The efficacy of oxygen use in the treatment of patients with respiratory conditions caused by COVID-19 has been demonstrated, but there is great opportunity to improve the effectiveness of its use if it is used in a rational, sustainable, and safe way. Bearing in mind that the efficacy of a health technology is measured by its benefit under actual conditions of use, practical actions can be taken to improve the use of medical oxygen and avoid oxygen shortages. A drug is considered to be used rationally when patients receive it according to their clinical needs, in doses appropriate to their individual needs, for an appropriate period, and at a low cost to them and their community. By providing instruction on the rational use of oxygen and promoting it, negative repercussions can be avoided, such as loss of efficacy as a result of activities related to oxygen storage, distribution, and administration. Rational use of oxygen also involves controlling waste due to leaks in storage and distribution systems, use of gas at incorrect pressures, use of incorrectly adjusted flowmeters, and disconnections, among other problems. Another aspect to consider is the provision of adequate technical support for all oxygen production systems, in terms of maintenance and calibration, availability of electrical energy, and specific knowledge about these systems. For these reasons, a set of guidelines has been put together for the development of an efficient management system to deal with situations of oxygen scarcity, both now and in the future.

For patients on HFNO with persistent hypoxaemia or respiratory distress:
• Check the equipment: inspect the exterior of the machine, the tubing (circuit), the prong for any sign of mechanical damage, confirm it fits and the filters are in place. Ensure the settings are appropriate and flow is max...imized.
• Check the oxygen source: there is sufficient oxygen available and flowing through the device. If FiO2 > 50% of oxygen is needed, the device must have a blender.
• Check there is no obstruction with secretions: patients with COVID-19 may have very thick secretions which may block small and large airways and cause sudden respiratory deterioration.

WHO recommends prompt recognition of progressive acute hypoxaemic respiratory failure when a patient with respiratory distress is failing to respond to standard oxygen therapy and adequate preparation to provide advanced oxygen/ventilatory support.
Hypoxaemic respiratory failure in ARDS commonly re...sults from intrapulmonary ventilation-perfusion mismatch or shunt and usually requires mechanical ventilation.
At any time, if there are urgent or emergent indications for intubation, do not delay.
WHO suggests that hospitalized patients with severe or critical COVID-19 with acute hypoxaemic respiratory failure that do not require emergent intubation be treated with HFNO, or CPAP or NIV (BiPAP) rather than standard oxygen therapy.
