The aim of this study is to determine the accuracy of devices called pulse oximeters which measure blood oxygen by shining light through fingers, ears or other skin, without requiring blood sampling.
You will have a small plastic tube placed in a wrist artery under local anesthesia. Standard and test pulse oximeters will be attached to your fingers, forehead or ears. You will be asked to rapidly breathe in and out of a tube through a mouthpiece, with a nose clip on your nose. The gas you will breathe will be adjusted to lower your blood oxygen saturation from its normal value of 95% - 98% to as low as 60% for less than 30 seconds. During these tests 20-25 small blood samples (each less than 2 ml) will be taken from the wrist arterial catheter, for a total of less than 50ml of blood.
An amount of 600 RMB will be paid for a completed test which normally takes about 45 mins.
