Lifebox and the WHO developed a tool with guidance for carers in low-resource settings working with patients with respiratory compromise and suspected or confirmed COVID-19. The tool chart shows that providing supplementary oxygen therapy is recommended if the patients Oxygen readings are below 94%.
The pulse oximeter is simply fitted onto the patients finger for instant oxygen & pulse readings so that the patient can be monitored for decline or improvement in their condition.
