Hypoxemia (or Hypoxaemia) is generally defined as decreased partial pressure of oxygen in blood, sometimes specifically as less than which, without further specification, would include both concentration of dissolved oxygen and oxygen bound to hemoglobin.

Headache as COVID-19 symptom could indicate milder disease, study finds

Researchers at the Hospital Universitario de La Princes in Madrid, Spain, found that patients with COVID-19 who developed headaches as an early symptom of infection had a milder illness and less risk of death.

Study offers explanation for silent hypoxemia in COVID-19 patients

One of the physiopathological characteristics of COVID-19 that has most baffled the scientific and medical community is what is known as "silent hypoxemia" or "happy hypoxia".

Anti-N-protein IgG may predict severity of COVID-19

A recent study by researchers at the University of Miami, Miami VA Healthcare System and Express Gene and published on the preprint server medRxiv in September 2020 reports on the prognostic significance of the anti-N Immunoglobulin G (IgG) antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Using computer simulations to examine personalized mechanical ventilation of COVID-19 patients

Initial clinical guidelines for mechanical ventilation of COVID-19 patients suggested following standard approaches used in the treatment of acute respiratory distress syndrome (ARDS), which is characterized by rapid onset of widespread inflammation in the lungs.

Keto diet could be beneficial for elderly COVID-19 patients

A recent study by researchers at Yale School of Medicine, New York University Langone Health and Washington University School of Medicine, claims that the ketogenic diet (high fat, low carbohydrate diet) is capable of mitigating clinical outcomes of coronavirus disease 2019 (COVID-19) in elderly people by improving immune-metabolic functions and reducing inflammation. The study is currently available on the bioRxiv* preprint server.

New simple way of detecting COVID-19 in blood plasma

Even as the COVID-19 pandemic claims increasing numbers of patients, testing numbers are rising in most nations at the leading edge. However, the current reverse transcriptase-polymerase chain reaction (RT PCR) testing is often unavailable and takes up to several days for results to arrive.

Study provides possible explanations for silent hypoxemia in COVID-19 patients

A new research study provides possible explanations for COVID-19 patients who present with extremely low, otherwise life-threatening levels of oxygen, but no signs of dyspnea (difficulty breathing).

Blood cell damage in COVID-19 may compromise oxygen transport

Researchers in the U.S. have shown that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may alter key protein structures on red blood cells and compromise the transport and delivery of oxygen in patients with coronavirus disease 2019 (COVID-19).
