Figure 2. All subjects reached successful treatment (SpO2 above 95%) and experienced significant increase in SpO2 within 24 h.

(A) O₂ saturation prior to treatment was significantly (p < 0.05) less than 95%, the defined successful treatment reached by all subjects. (B) O₂ saturation significantly increased in subjects 24 h after treatment (paired t-test, p < 0.001, only subjects with data before and after treatment included). O₂ saturation continued to rise until the defined cure of greater than 95% O₂ saturation was reached.
