Nocturnal desaturation
Desaturation is a decrease in oxygen saturation, which is a measure of how much oxygen is being carried in the blood.
Desaturation occurs when the oxygen saturation level in the blood drops below normal levels. This can lead to symptoms such as shortness of breath, confusion, and fatigue. Severe desaturation can be life-threatening and may require medical intervention to restore adequate oxygen levels.
It is a device for measuring the oxygen saturation of arterial blood.
The desaturation point is critical because it represents the level at which oxygen saturation in the blood drops to a potentially dangerous level. This can impair essential bodily functions and lead to tissue damage or organ failure if left untreated. Monitoring and maintaining oxygen saturation above this point is crucial to ensure the body's oxygen needs are met.
A respirometer works by measuring the amount of oxygen breathed in and measuring the amount of carbon dioxide breathed out. It also measures how long it takes from a breath in to a breath out for normal respiration.
An oxygen meter measures the amount of oxygen from the pulse in a finger by being placed on an individuals fingertip which causes two wavelengths to be able to pass through the individual to a photo detector.
VO2 max measures the maximum amount of oxygen that a person can use during intense exercise. It is influenced by three main factors: the ability of the heart to pump blood, the efficiency of the lungs to extract oxygen, and the capacity of the muscles to utilize oxygen for energy production.
A pulse oximeter measures the body's oxygen saturation with a small clip.

HR changes in response to workload, the harder you work the more oxygen is needed. Blood is the transport vessel for that oxygen. Faster HR = more blood and therefore more oxygen.
