Application of oxygen therapies and respiratory support measures is challenging because COVID-19 differs from other viral respiratory infections (such as influenza and seasonal endemic coronavirus). Given the lack of knowledge supported by scientific evidence, medical treatment has been administered based on expert opinions.

It’s been well established that face masks with a reservoir bag, while a first line therapy, provide little when it comes to patient comfort. The air is dry, and the masks prevent patients from doing many basic functions. Wearing a face mask hinders the patient from communicating, drinking, or eating without removing the mask. Face masks can also c...
A major challenge for healthcare providers and organizations caring for patients with COVID-19 is access to beds and rooms. ICUs and step-down units were often beyond capacity, highlighting the need for interventions that can be done safely outside of an ICU setting. High flow oxygen therapy has proven to be one of these vital interventions that ca...
The use of high flow oxygen therapy (HFNO) has been evaluated in several studies specifically focused on patients with COVID-19. A retrospective study out of France found patients who undergo HFNO were less likely to need mechanical ventilation (56% of HFNO group versus 71% in non-HFNO group).5 The mortality rate of these patients with COVID-19 res...
High flow O2 therapy is not only a practical intervention for patients with COVID-19 related hypoxemic respiratory failure, but it also provides additional physiological benefits. These benefits include: 2 1. Alveolar recruitment 2. Improved perfusion matching 3. Reducing airway resistance 4. Reduced respiratory effort 5. Decreased oxygen dilution ...

As the COVID-19 pandemic evolves, new effective treatment options are essential for reducing morbidity and mortality as well as the strain placed on the healthcare system. Since publication of our initial review on hyperbaric oxygen treatment (HBOT) ...
Rationale In patients with COVID-19 pneumonia and mild hypoxaemia, the clinical benefit of high-flow nasal oxygen (HFNO) remains unclear. We aimed to examine whether HFNO compared with conventional oxygen therapy (COT) could prevent escalation of respiratory support in this patient population.
Apr 17, 2023 · In this review, we summarize the classical oxygen therapies and highlight several potential micro and nanotechnological strategies to be employed as oxygen therapy alternatives in COVID-19 patients.
