Why am I short of breath but my oxygen saturation is good?
Shortness of breath does not always indicate that you are hypoxic. In other words, your level of dyspnea, or air hunger, does not always correlate with your oxygen saturation. This means that you can be short of breath, even extremely short of breath, even in the presence of normal oxygen saturation.
