Authors' conclusion

Vaping/e-cigarette use was neither associated with clinically significant hypoxemia during the first hour in the postanesthesia care unit nor with an increase in pulmonary complications.

As reported in the abstract

TWA SpO2/FIO2 ratio in PACU
  • Equivalent to a 4% change in SpO2 at a 30% FIO2 (or at a fixed FIO2)
