Central nervous system oxygen toxicity (CNS-OT)

Simulation activity which aims to ensure hyperbaric physicians have recognised training to manage CNS-OT events.

Participate in a CNS-OT-related activity - find recognised courses and workshops on the college website.

CPD Value: CPD participants may claim this under Emergency response Central nervous system oxygen toxicity (CNS-OT) activity.

Recognised emergency algorithms

At this stage, ANZCA and the DHM Sub-Committee do not endorse any one emergency algorithm for CNS-OT situations. However, departments have specific procedures for emergencies as recommended by ASNZ 4774.2 for all accredited departments.

Bitterman N, Bitterman H. Oxygen toxicity. In: Mathieu D, editor. Handbook on hyperbaric medicine. Dordrecht (The Netherlands): Springer; 2006. p. 731-65. This chapter will present our current knowledge on the major toxic manifestations of oxygen; the clinical features-descriptions and incidence of symptoms, mechanisms underlying the oxidative insult, the time-duration relationship defining the safety limits, risk factors leading to enhanced toxicity, and strategies for protection
Cooper JS, Phuyal P, Shah N. StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2020 Jan-. Oxygen Toxicity. [Updated 2023 Aug 1]. Oxygen is vital to sustaining life. However, breathing oxygen at higher than normal partial pressure leads to hyperoxia and can cause oxygen toxicity or oxygen poisoning. The clinical settings in which oxygen toxicity occurs are predominantly divided into two groups; one in which the patient is exposed to very high concentrations of oxygen for a short duration, and the second where the patient is exposed to lower concentrations of oxygen but for a longer duration. These two cases can result in acute and chronic oxygen toxicity, respectively. Acute toxicity typically manifests with central nervous system (CNS) effects, while chronic toxicity has mainly pulmonary effects. Severe cases of oxygen toxicity can lead to cell damage and death. Those at particular risk for oxygen toxicity include hyperbaric oxygen therapy patients, patients exposed to prolonged high levels of oxygen, premature infants, and underwater divers. This activity reviews the etiology, presentation, evaluation, and management of oxygen toxicity and reviews the role of the interprofessional team in evaluating, diagnosing, and managing the condition.

CPD Activity Guide
This guide contains a list of all the activities associated with the ANZCA and FPM CPD Program, as well as links to associated individual activity guides and forms.
ANZCA and FPM CPD Program: Central nervous system oxygen toxicity ER session guideline
This guideline assists hospitals, private practice groups and other course providers develop and conduct Central Nervous System oxygen toxicity (CNS-OT) emergency Response (ER) sessions. It defines the learning objectives and other requirements for education providers to become recognised CNS-OT ER providers for the purposes of the ANZCA and FPM CPD program.

For CPD participants, this guideline provides information on what recognised CNS-OT ER sessions involve and how to record this activity.
Central Nervous System oxygen toxicity (CNS-OT) - recognition of suitability application form
Course providers must apply for college recognition of your session as a suitable CNS-OT ER activity for the ANZCA and FPM CPD program. Providers are encouraged to develop sessions that also satisfy local needs, incorporating local staff, work environments and equipment.

ANZCA: Diving & Hyperbaric Medicine Library Guide
This guide has been designed for anaesthetists interested in Diving & Hyperbaric Medicine to locate relevant resources on this topic, including those available through the ANZCA library.

Handbook on Hyperbaric Medicine by Daniel Mathieu [ed] The decade since the first Handbook on Hyperbaric Medicine has seen major advances: studies have clarified the actions of hyperbaric oxygenation; clinical practice is becoming more scientific; various organisational and operational guidelines are now widely accepted. This new Handbook arises from the EU Co-operation in Science and Technology (COST) programme for hyperbaric medicine, COST B14, in combination with the results of a number of recent experimental and clinical studies.
