This question is answered by using Boyle's law which states that P1V1=P2V2. Therefore 3ml x 810mmHg = 1.7ml * P2. P2 in this case is 1429mmHg. Air flow would be out of the body into the environment, where atmospheric pressure is approximately 760 mmHg. Higher pressure flows into lower pressure areas.
