s0 s0 s0 s0 s0 s0 s0 s0 s0 s0 s0
s0 Hospital (the “Ether Dome”) on October 16, 1846. Crawford Long used ether earlier but
s0 s0 s0 s0 s0 s0 s0 s0 s0 s0 s0 s0 s0
s0 did not publish or demonstrate publicly. Horace Wells attempted nitrous oxide but failed.

s0 Boyle’s machine (1917) was for ether/oxygen without CO₂ absorption. Guedel described
s0 s0 s0 s0 s0 s0 s0 s0 s0 s0
s0 airway stages. Magill developed endotracheal tubes.
