An O2 delivery device takes separate pressurized (50 psi) air and O2 sources as input, then mixes these gases through a precision valve. What does this describe?

What are the two common indications for HeO2 therapy?   I. Carbon monoxide posoning II. Upper airway mass III. Pulmonary hypertension IV. Pediatric status asthmaticus

A patient is currently on oxygen via oxygen simple mask at 12 LPM. The patient is breathing at a rate of 30 breaths/min, SpO2 at 87% and has bilateral rhonchi on auscultation. What should the therapist do next?
