The discovery of poor air quality at Misericordia Community Hospital in Edmonton, Alberta, has prompted warnings to 473 patients who may have been affected, according to an article on the Edmonton Journal website.
Covenant Health said the issue involved a failure to maintain adequate positive air pressure in three operating rooms and two labor and delivery suites.
The problem occurred between May 21 and July 18.
Remedial action has been undertaken and there is no ongoing increased risk to patients, according to Covenant.
