You obtain an spo2 reading of 100% on a patient receiving oxygen via a nonrebreathing mask. what range of arterial po2s is possible in this patient

SpO2 measures blood oxygen saturation levels. Normal is between 95-99%, and the only way to achieve 100% is with supplemental oxygen. Once you know the SpO2 value, you can estimate the arterial PO2 value using the 4-5-6-7-8-9 rule. For example:
  SpO2 70% = PO2 of 40
 SpO2 80% = PO2 of 50
  SpO2 90% = PO2 of 60
 SpO2 100% (our patient) = PO2 of 70.
  If the SpO2 were to drop a bit from 100%, the PO2 would also drop a bit. The range of possible PO2 values in our patient is: 60-70.

Molecular signals that may stimulate or halt cell division, tell cells to differentiate or initiate cell death. What happens if cell cycle regulators don't function properly? An organism may end up with too few or too many cells The cell replicates its DNA
