Tom Greensmith provides a case-based approach to blood gas acide base analysis, including normal values and calculations required, followed by a recording of a Q&A session. This 1.5 hour webinar is from a Regions Now event brought to you by our Metropolitan Region. Regions Now events comprise an introductory lecture with supporting content available one week before a live lecture. This is followed by a one-week online discussion forum allowing participants to offer observations about the lessons learned and describe their own experience in handling cases. Regions Now sessions are free to BSAVA members and available for non-members to book - visit the Regions page of the BSAVA website for details of future Regions Now events. Recordings will be available for 3 years via the BSAVA Webinar Library.
