# Continuous pulse oximetry ( SpO2 ): The placement of this device ( usually on one of the fingers ) allows for early detection of a fall in a patient's haemoglobin saturation with oxygen ( hypoxaemia ).

High blood and tissue levels of oxygen can be helpful or damaging, depending on circumstances and oxygen therapy should be used to benefit the patient by increasing the supply of oxygen to the lungs and thereby increasing the availability of oxygen to the body tissues, especially when the patient is suffering from hypoxia and / or hypoxaemia.

It may also be indicated for any other patient where their injury or illness has caused hypoxaemia, although in this case oxygen flow should be moderated to achieve target oxygen saturation levels, based on pulse oximetry ( with a target level of 94 – 98 % in most patients, or 88 – 92 % in COPD patients ).

The latter means that, should attempts at endotracheal intubation fail and the patient cannot be ventilated, there is a prospect for neuromuscular recovery and the onset of spontaneous breathing before hypoxaemia occurs.
