After breathing in a plastic bag, what happens to your duration of suspended breathing?

Question

do you hold your breath for longer or shorter

Answer 1

there will be an increase in the levels of carbon dioxide, bicarbonates, and hydroxides in your blood. The increase becomes stimuli to your brain. Your brain will process and sends reply to your tissues (especially those in respiratory system) that will make you exhale for normalization of blood ph.

Answer 2

You will hold your breath for a shorter time due to the lungs needing more oxygen to aerate pulmonary venous blood due to a very complex process.
