Perth doctor rigs up solution to feared ventilator shortage

"SNIP......

A doctor in eastern Ontario has improvised a way to double his small hospital's ventilator capacity in preparation for a possible COVID-19 outbreak.

Anesthetist Alain Gauthier, who has a PhD in respiratory mechanics and works in Perth, west of Ottawa, spotted the idea in a YouTube video.

In basic terms, the rig involves running two hoses from one ventilator and doubling the power.

In just 10†minutes and with the help of some extra tubing, Gauthier made it possible to double the number of patients ventilated in the hospital at once, if needed.

But there's a catch: the two patients attached to the same ventilator need to be of similar size and lung capacity. And if one patient declines, things will need to be adjusted.

3. Was wondering other day if more than one could be hooked up? Not optimal

Not optimal, but even if it is just adequate, itís better than doing normal. Iím sure some patients would require special settings.

Also, read than can use anesthesia machines. Plus, some patients can probably be taken off quicker than normal, or get by with shorter periods.

The best professionals will figure it out, rather than relying on normal/preferable procedures.

6. Not optimal, but every little bit helps.

It's amazing how people can shine under pressure sometimes.
