Mental Health First Aid Guidelines
4 April 2020
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.

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 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.
This collection of posters are intended for health care workers, biomedical engineers and staff of health facilities in charge of caring, cleaning, decontaminating and sterilizing respiratory medical equipment in hospitals and health facilities. They include checklists to ensure the optimal infectio...n prevention and control during their use and between patients.
They describe the procedures to follow (Checklists) to clean, decontaminate and sterilize different respiratory devices:
Oxygen concentrators,
Non-invasive mechanical ventilation equipment: High flow nasal cannula, BiPAP/CPAP,
Mechanical ventilators,
Pulse oximeters and monitors.

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.

Avec l’augmentation soudaine du nombre d’hospitalisations causées par la pandémie de COVID-19 en Amérique latine et dans les Caraïbes, et étant donné la rareté des ressources humaines et matérielles telles que les équipements médicaux et les gaz médicaux, il est devenu nécessaire de ...repenser les modèles de soins dans la Région dans le but d’optimiser l’utilisation de ce qui est disponible et de s’assurer qu’un plus grand nombre de patients recevront l’oxygène dont ils ont besoin en quantité et en qualité. L’oxygène est inclus dans la liste des médicaments essentiels de l’Organisation mondiale de la Santé et sert à soigner les patients à tous les niveaux des réseaux de services de santé intégrés. L’efficacité de l’utilisation de l’oxygène est démontrée dans le traitement de patients atteints de maladies respiratoires causées par la COVID-19, et cette efficacité pourra être grandement améliorée si on encourage le recours rationnel, durable et sûr à cette pratique.

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.
