Cheyne Stokes Syndrome diagnosed with a 3D oximeter

A patient with severe heart failure had a resting SpO2 values ​​at the lower limit of normal , but had brief episodes of desaturation ( SpO2 falls ) as if hypo ventilated.

He also reported wheezing for minimal effort and episodes of nocturnal awakenings with a sense of suffocation.

He performed a 3D oximetry test during his sleep with a particular oximeter equiped with an accelerometer that allows the phases of movement (ie awake) to be distinguished by presumed sleep periods and to identify the positions taken during the sleep just as a polysomnography does.

The result was surprising: at first glance the plot suggested the presence of typical rapid desaturation sleep apnea syndrome (OSAS ).
