PRODUCTS: Postoperative & Recovery
Following completed anaesthesia the patient's expiration air contains anaesthetic gases for a relatively long period.

Often, It is more suitable for everybody if patients exhale the gas in the post-op ward instead of in the operating theatre. To avoid excessively high levels of gases in the theatre air a specially designed Chin mask is used which effectively sucks up the gases exhaled by the patient during the first 15-20 minutes.
