Understanding the Impact of COVID-19 on Breathing

COVID-19, caused by the novel coronavirus, primarily affects the respiratory system and breathing. It can lead to symptoms such as cough, shortness of breath, and in severe cases, pneumonia. Understanding how COVID-19 affects breathing and monitoring oxygen levels is crucial for detecting potential complications and seeking appropriate medical help.

The Role of Oxygen Levels in Assessing Breathing

Oxygen saturation, measured as SpO2, is a vital metric for assessing respiratory function. It indicates the percentage of hemoglobin carrying oxygen in the blood. Typically, a healthy individual maintains oxygen saturation levels of 95% or higher.

Can an iPhone Accurately Measure Oxygen Levels?

While iPhones come equipped with advanced health monitoring features, they do not have the capability to directly measure SpO2 levels. The built-in sensors, such as the heart rate monitor, may provide useful data for general health tracking, but they are not designed to measure oxygen saturation accurately.

To measure oxygen levels accurately, specialized medical devices, like pulse oximeters, are considered the gold standard. These devices utilize infrared light absorption to determine SpO2 levels and provide reliable readings. It is essential to consult a healthcare professional or use a certified medical device for accurate oxygen level measurements.
