Abstract: Embodiments of the present disclosure pertain to methods of detecting hypoxemia in a subject by: (1) receiving a blood sample from the subject; (2) measuring the T2 relaxation time constant of the blood cell (e.g., blood cell pellet) of the blood sample (T2P value); and (3) correlating the measured T2P value to hypoxemia. In some embodiments, the methods of the present disclosure also include a step of correlating the measured T2P value to the subject's susceptibility to one or more hypoxemia-related conditions. Further embodiments of the present disclosure pertain to systems for detecting hypoxemia in a subject in accordance with the methods of the present disclosure.

Abstract: A medical testing system comprises a housing, at least one magnet assembly configured around a probe configured to accept a human finger, formed in the housing wherein the at least one magnet assembly creates a permanent magnetic field around the probe, an RF signal generator configured to create a temporary magnetic field perpendicular to the permanent magnetic field in the housing, and an NMR coil assembly wherein a change in the permanent magnetic field induces a voltage in the NMR coil assembly.
