An Oxygen Study is a series of separate tests designed to evaluate oxygen level in the blood, heart rate response to exercise, or a patient's perceived shortness of breath on exertion. These studies can be used as a quick and simple assessment of patient conditioning.
There are two types of Oxygen Studies performed at Our Lady of the Angels Hospital.
The first is Arterial Blood Gas (ABG). During an ABG blood is drawn from an artery, where the oxygen and carbon dioxide levels can be measured before they enter body tissues.
In the Six-Minute Walk Study, patients are placed on a tread mill and asked to walk as much as possible for six minutes. Patients may speed up, slow down or rest as necessary. Because of physical exertion, some patients may temporarily become short of breath. Blood pressure, heart rate, respiratory rate, and resting blood saturation will be measured after the test. Oxygen saturation will be taken during the test.
