Respiratory

Respiratory Rate

What is it? Respiratory rate refers to the number of breaths you take in per minute. This value shows the pattern, speed and depth of your breath. Every time your chest rises, it creates the process of oxygen and carbon dioxide exchange to support the body system.

How do I interpret this value? A resting respiratory rate may decrease as you get fitter, while a high rate may occur when you have a fever, asthma, or panic attack. Abnormal values could be indicative of bigger health problems such as alcohol poisoning, opioid overdose, or stroke. Maintaining a healthy lifestyle and seeking medical attention, when necessary, can help improve respiratory rate.

How is it measured? Respiratory rate is measured by the colour changes of the blood flow under the skin, which contain information regarding breathing signals.

Oxygen Saturation

What is it? Oxygen saturation reflects the amount of oxygen in your blood. Oxygen is very important to life as your organs and tissues require a certain amount of oxygen to work properly. When oxygen arrives in your cells, they are utilised to create energy to support all the body processes, including thinking and digesting.

How do I interpret this value? Hypoxemia means your oxygen saturation is lower than the normal range. It could be caused by lung or heart problems or being at high altitudes. Your oxygen saturation should be kept above 95 percent in order to ensure your body is transporting or absorbing enough oxygen.

How is it measured? Oxygen saturation is measured by analyzing the composition of oxygenated and deoxygenated hemoglobin under the skin. A video camera can be used to detect these changes and calculate oxygen saturation levels.
