i,- i,- i,- i,- i,- i,- i,- i,-
decreases to 144 beats per minute, his respirartory rate decreases to 36

is intubated orotracheally without difficulty. Initially, his ventilations are
i,- i,- i,- i,- i,- i,- i,- i,- i,-
easily assisted with a bag-mask device. It becomes more difficult to
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
ventilate the patient over the next 5 minutes, and his hemoglobin oxygen
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
saturation level decreases from 98% to 89%. The most appropriate next
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
