Can the flu cause hypoxia?
Introduction. Influenza is known to cause serious illness, including severe hypoxemia and acute respiratory distress syndrome due to viral pneumonitis.
Can pneumonia cause low oxygen levels?
He pointed out that unlike normal pneumonia, in which patients will feel chest pain and significant breathing difficulties, initially COVID-19 pneumonia causes oxygen deprivation that is difficult to detect since the patients do not experience any noticeable breathing difficulties, hence causing a condition which he …
What condition can be a complication of influenza pneumonia?
Some flu-related complications aren’t as severe and may include a sinus or an ear infection. More serious complications can include bronchitis and pneumonia, which affect the lungs. Bronchitis occurs when inflammation develops in the lining of the bronchial tubes.
How does pneumonia affect oxygenation?
The infection causes the lungs’ air sacs (alveoli) to become inflamed and fill up with fluid or pus. That can make it hard for the oxygen you breathe in to get into your bloodstream.
What viruses cause hypoxia?
Table 2
| Respiratory Virus | Cytokines associated with pulmonary inflammation | Presence or absence of hypoxia |
|---|---|---|
| Influenza virus | IFN-γ, TNF-α, and IL-1 in BALF | Hypoxemia |
| Respiratory Syncytial Virus | IL-6, IL-8, GM-CSF, IFN- γ, TNF-α, IL-1β, G-CSF, and MIP-1β in nasal washings | Hypoxia |
How does influenza affect the body?
The flu is a virus that infects your upper respiratory tract (throat, sinuses) and it can also infect your lower respiratory tract (lungs). When the virus infects your lungs, your body tries to fight the infection. But, if the infection is hard to clear up you may develop viral pneumonia.
Can a virus cause low oxygen levels?
One of the biggest and most life-threatening mysteries is how the virus causes “silent hypoxia,” a condition when oxygen levels in the body are abnormally low, which can irreparably damage vital organs if gone undetected for too long.
How does influenza cause pneumonia?
Although the body would usually be able to fight the buildup away, influenza changes that. With a weakened immune system, your body may not be able to get over the foreign bacteria and viruses. This is how those with influenza can easily turn their flu into something much worse — pneumonia.
Can influenza affect the brain?
Brain flu is a very rare neurological complication of the influenza virus. It can lead to an altered mental status and other neurological symptoms.
Does fever reduce oxygen saturation?
The average rise in SO2 was 1.55 ± 1.79% (p = 0.001). Conclusions: Fever in children is associated with decreased SO2. This decrease is not clinically significant in patients with normal baseline SO2.
