The air sacs in COVID-19 patients’ lungs do not fill with fluid or pus as in normal pneumonia infections but rather the virus only causes the air sacs to collapse, thereby reducing the oxygen levels that lead to hypoxia in these patients but still maintains the lungs’ normal ability to expel carbon dioxide.

What time of day is oxygen highest?

Concentrations of oxygen can decrease significantly during the night, due to respiration. DO concentrations are usually highest in the late afternoon, because photosynthesis has been occurring all day.

What is oxygen level with Covid?

Goal of Oxygenation

The optimal oxygen saturation (SpO2) in adults with COVID-19 who are receiving supplemental oxygen is unknown. However, a target SpO2 of 92% to 96% seems logical, considering that indirect evidence from patients without COVID-19 suggests that an SpO2 of <92% or >96% may be harmful.

What are the 4 stages of pneumonia symptoms?

Stages of Pneumonia
  • Stage 1: Congestion. During the congestion phase, the lungs become very heavy and congested due to infectious fluid that has accumulated in the air sacs. …
