A pulse oximeter is a small device that can typically be clipped on a finger (toe or earlobe is also possible) to measure oxygen levels in the blood. This works completely painless and will give you a reading within a few seconds

A learning environment representing providers from variably-resourced practice settings, the mission of the Global Anesthesia and Critical Care Learning Resource Center is to improve equity in peri-operative healthcare access locally and across the globe through medical education, engaging discussions, remote mentorship, and building professional networks

It is intended for use among clinicians taking care of moderate to severe COVID-19 cases. The COVID-19 outbreak has brought with it the need for improved critical care for patients who develop severe disease. The majority of COVID-19 patients present with mild to moderate illness, 15% develop severe illness and about 5% develop critical conditions needing intensive care unit (ICU) care, requiring noninvasive or invasive ventilatio

Interim Guidance 15 April 2020 These technical specifications describe the minimum requirements that invasive and non-invasive ventilators must comply with to ensure quality, safety and effectiveness when used for the management of COVID-19. All these ventilators should be provided with accessories, consumables and spare parts as required to operate for minimum duration of 3 months. It is advisable to follow the maintenance guidance for the replacement of accessories and consumables, and for the safe decontamination of the reusable parts provided by the manufacturer

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 the minimum requirements that a PSA Oxygen Plant must meet for use for the administration of medical-grade oxygen

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

COVID-19 e oxigênio: Os dados da China sugerem que embora a maioria das pessoas com COVID-19 tenham doença leve (40%) ou moderada (40%), cerca de 15% apresentam doença grave que requer oxigenoterapia, e 5% ficam em estado crítico e precisam de tratamento em uma unidade de terapia intensiva. Além disso, a maioria dos pacientes críticos com COVID-19 precisará de ventilação mecânica.2,3 Por esses motivos, as unidades de saúde que tratam da COVID-19 devem estar equipadas com oxímetros de pulso, sistemas de oxigênio em funcionamento, incluindo interfaces de administração de oxigênio de uso único. A oxigenoterapia é recomendada para todos os pacientes graves e críticos com COVID-19, em doses baixas, variando de 1-2 L/min em crianças e começando com 5 L/min em adultos com cânula nasal, fluxos moderados para o uso em máscara de Venturi (6-10 L/min); ou fluxos mais altos (10-15 L/min) com o uso de uma máscara com bolsa reservatório. Além disso, o oxigênio pode ser administrado em fluxos mais altos e em concentrações maiores, usando uma cânula nasal de alto fluxo (CNAF

9 April 2020 WHO has published the guidance “Clinical management of severe acute respiratory infection (SARI) when COVID-19 disease is suspected” This document is intended for clinicians taking care of hospitalized adult and paediatric patients with severe acute respiratory infection (SARI) when COVID-19 infection is suspected. Optimized supportive care should be provided to ensure the best possible chance for survival of COVID-19 patients as described in the WHO guidance: 1. Management of severe COVID-19 requires oxygen therapy and monitoring. Supplemental oxygen therapy should be given immediately to patients with SARI and respiratory distress, hypoxaemia or shock. 2. Management of critical COVID-19 (acute respiratory distress syndrome (ARDS)) requires advanced oxygen/ventilatory support
