● In a patient with stable chronic disease (e.g., COPD), an SpO2of 92% or less should prompt referral for further investigation of the need for long-term oxygen therapy.1 Measuring Your Oxygen Level Today’s medical experts have access to a wide variety of SpO2monitoring tools, including...
A special form of hypoxemia has occurred, particularly in connection with COVID-19: Many patients show no signs of shortness of breath or accelerated breathing despite severe hypoxemia with oxygen saturation levels as low as below 70%. This form of hypoxemia is particularly dangerous because, desp...
In addition, some studies have also indicated that the underlying physical condition of patients may be associated with the incidence of AKI after surgery. For instance, anaemic patients are more likely to develop AKI than patients with normal hemoglobin levels [15], and malnourished patients also ...
When red blood cells have hemoglobin S, and are subjected to low oxygen levels, they can become crescent or "sickle-shaped" and do not easily move through capillary vessels with small diameters, thus depriving tissues of exchanging oxygen and carbon dioxide. In extreme situations, tissue can ...
We examined the effects of exercise on plasma BNP levels in patients with COPD who have normal right ventricular function METHODS: Seventeen patients with a diagnosis of COPD and normal right ventricular function demonstrated by radionuclide ventriculography, and 17 age-and sex-matched healthy subjects...
Pulse oximetry utilizes a pulse oximeter device to gauge the oxygen saturation in your red blood cells. The device will indicate your blood oxygen levels as a percentage. Individuals with lung conditions like chronic obstructive pulmonary disease (COPD), asthma, or pneumonia, as well as those who...

The ideal respiration frequency at rest for maximum possible brain- and body-oxygen levels corresponds to the automatic or unconscious breathing with only X breaths/min (find out this exact number X in the bonus content). …about 3-4 breaths per minute (see Buteyko Table of Health Zones for...
Hemoglobin is the protein in red blood cells responsible for transporting oxygen throughout the body. Hematocrit, on the other hand, measures the percentage of your blood that is made up of red blood cells. While hemoglobin indicates the maximum amount of oxygen your blood can carry, hematocrit...
Persistent respiratory syncytial virus (RSV) infections have been associated with the exacerbation of chronic inflammatory diseases, including chronic obstructive pulmonary disease (COPD). This virus infects the respiratory epithelium, leading to chronic inflammation, and induces the release of mucins and ...
