Can you extend a snorkel?

There are two reasons why snorkels cannot get longer. A longer snorkel would increase the dead air space, which makes breathing more difficult and ensures that used breathing air is inhaled again. Here there is the danger of pendulum breathing. On the other hand, the water pressure makes breathing more difficult.

How long is the average snorkel?

The ideal length of a snorkel is 12 to 15 inches.

Free diving deeper with a longer tube will also make it harder to clear a long snorkel when you return to the surface. It will take in a larger volume of water while submerged.

Can you breathe through a long tube?

Shallow breaths won’t flush the tube of CO2, and you wind up pushing spent breath a bit backwards and a bit forwards. Your lungs get that burning feeling, you get dizzy and headachy, then you pass out from the reduced oxygen if you keep it up too long. With normal snorkels, it’s really hard to get to ‘too long.

Can you breathe through a tube?

Intubation is a procedure that’s used when you can’t breathe on your own. Your doctor puts a tube down your throat and into your windpipe to make it easier to get air into and out of your lungs. A machine called a ventilator pumps in air with extra oxygen.

How does a snorkel tube affect breathing?

Including the internal volume of the mask in the breathing circuit greatly expands the dead space. A smaller diameter tube reduces the dead volume, but also increases resistance to airflow and so increases the work of breathing.
