Many people with chronic obstructive pulmonary disease have a low partial pressure of oxygen in the blood and high partial pressure of carbon dioxide.Treatment with supplemental oxygen may improve their well-being; alternatively, in some this can lead to the adverse effect of elevating the carbon dioxide content in the blood (hypercapnia) to levels that may become toxic.
Studies of miners and astronomers working at 3000 meters and above show improved alveolar P O 2 with full acclimatization, yet the P O 2 level remains equal to or even below the threshold for continuous oxygen therapy for patients with chronic obstructive pulmonary disease (COPD). [100] In addition, there are complications involved with ...
In context of acute hypoxemia, oxygen therapy should be titrated to a target level based on pulse oximetry (94–96% in most patients, or 88–92% in people with COPD). [ 12 ] [ 8 ] This can be performed by increasing oxygen delivery, described as F I O 2 (fraction of inspired oxygen).
The disease affects people at different fitness levels, and patients with COPD may have additional illnesses like heart disease, osteoporosis, and anemia that should be considered when crafting an ...

Integrated pulmonary index (IPI) is a patient pulmonary index which uses information from capnography and pulse oximetry to provide a single value that describes the patient's respiratory status. IPI is used by clinicians to quickly assess the patient's respiratory status to determine the need for additional clinical assessment or intervention.
Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia. Respiratory failure is classified as ...
Normal arterial blood oxygen saturation levels in humans are 96–100 percent. [1] If the level is below 90 percent, it is considered low and called hypoxemia . [ 2 ] Arterial blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed.
