How much suction required to lift?

[Lisa Helme]

Hi - am looking for some data points on how much suction is required to lift an object at different weights and volumes.

Especially interested in any data relative to displacing an object caught in the throat if you are choking.

Appreciate any help!

Well the problem with suction in this sense is that it acts in all directions unilaterally. i.e.
rather than pull an object out, it will have more of a tendency to collapse the throat, making the problem worse.

If you use a drinking straw to drink a milkshake, you're OK as long as the shake isn't too thick, and the straw is rigid. But if you flatten the straw, decreasing its rigidity, it will simply collapse every time you suck on it.
