Appeal No. 95-3184 Application 07/981,910 which communicates with the face mask A and the patient’s airway [column 3, lines 55 through 68]. The examiner’s conclusion that Emerson teaches or would have suggested a ventilating method meeting the limitations in appealed claim 33 requiring the addition in succession of pulses of small volumes of gas to provide successively greater volumes of gas successively increasing in pulsatile form the pressure of the gas in the patient’s airway wherein the successive increase in pulsatile form of the pressure is caused solely by the successive addition of the small volumes of gas is not well taken. While Emerson’s vibration of the column of gas in the patient’s airway would appear to supply to the airway a plurality of pulses of small volumes of gas, it is not apparent, nor has the examiner explained, how these pulses would be additive in succession to provide successively greater volumes of gas successively increasing in pulsatile form the pressure of the gas in the airway. Indeed, Emerson’s teaching that the vibrations or pulses applied to the column of air cause the air to move first in one direction and then in the opposite direction would seem to belie any such conclusion. -7-Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
