Sinus arrythmia with unifocal PVCs... probably due to hypoxia.
I'd say seizure and there's a zillion reasons why you could have one of them. It explains the initially low SpO2, the hypertension, ALOC and it can explain the pupils. The ectopy on the ECG could then be from hypoxia.
Not too sure about the vomiting / blood stuff. Trauma from the airway has already been said and I'd agree with that.
What makes you say it wasn't a seizure?
