Speaking in Moose Jaw, Wall admitted the government may have made a mistake when it considered moving the piece of medical equipment.
There was a lot of anger when the government said there wouldn't be room for the chamber in the new hospital.
Health Minister Dustin Duncan at one point suggested the equipment might be moved to an out-patient facility elsewhere or patients might be referred to other provinces.
The therapy involves resting in a pressurized chamber filled with oxygen and can be used to treat carbon monoxide poisoning and help heal wounds.
Wall said local MLAs Warren Mitchelson and Greg Lawrence made it clear the decision to move the chamber was not a popular one.
"They've been pretty adamant. They've been working through me directly, through the health minister," Wall said after his speech Wednesday. "(Agriculture Minister) Lyle Stewart represents the area right around Moose Jaw. He's been raising it in cabinet.
"We want to make sure that we're a government that's listening carefully to people and that can admit when a mistake's been made."
Wall said the hyperbaric debate provided a lesson for the government.
"It's pretty helpful to us to realize that when these recommendations are made there's probably a good reason to make them and there's also a good reason to ... look even more carefully at the implications."
