DENTAL PATIENT CAN GIVE HERSELF GAS (Oct, 1934)
Looks easier than a balloon and a box of whippets.
DENTAL PATIENT CAN GIVE HERSELF GAS
Dental patients can now administer their own anesthesia. The gas, the same as that now used by dentists, is a mixture of nitrous oxide and oxygen. A tube leading to the tanks containing the gases is equipped with a pistol-like control. While wearing a mask, a patient with this control can release as much gas as she needs to overcome the pain. The patient does not lose consciousness but suffers no pain.
