Simple pulmonary stress test
Nocturnal desaturation
Desaturation is a decrease in oxygen saturation, which is a measure of how much oxygen is being carried in the blood.
It is a device for measuring the oxygen saturation of arterial blood.
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.
A pulse oximeter measures the body's oxygen saturation with a small clip.
Measures the amount of oxygen in the exhaust
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.
An oxygen meter measures the percentage of oxygen in the air being tested.

oxygen consumption
An oximeter measures the amount of oxygen in the blood by analyzing blood volume in the skin. The method for measuring oxygenation is the same, regardless of the device or the location where it is used.
