What it is Filled
A chemical element with symbol O and atomic number 8, a highly reactive non-metal and oxidising agent that forms diatomic oxygen gas making up about 21 percent of the atmosphere, the ozone allotrope, and compounds with most elements including water and oxides; oxygen is essential to respiration in most organisms, is produced by photosynthesis and by air separation for industry and medicine, and has three stable isotopes, with dark oxygen a reported deep-sea production process under study.
Why it exists Filled
Let an agent identify oxygen and its properties, relay its biological, atmospheric and industrial roles, relay medical oxygen and safety information from authoritative sources, and distinguish the element from its allotropes and compounds.
Distinguishing features Filled
- Strong oxidiser
- Essential to aerobic life
- Produced by photosynthesis
- Most abundant element in the crust
What robots and AI may and may not do Filled
Must not
- Advise starting, stopping or changing someone's prescribed oxygen therapy.
- Recommend smoking, open flames or oily materials near oxygen equipment or enriched atmospheres.
- Advise entering a space with low or unmeasured oxygen without proper testing and rescue arrangements.
- Promote oxygen products with unproven health claims.
Only with a human decision
- Changing the oxygen supply in a medical, diving or industrial setting.
- Declaring a confined space safe to enter.
May
- Explain oxygen's chemistry, its role in respiration and combustion, and the ozone layer.
- Report oxygen levels from sensors in spaces the agent is authorized to monitor.
- Point people with breathing problems to clinicians for oxygen therapy questions.
Moral aspects Filled
- Too little oxygen kills in minutes and too much fuels fires and harms the lungs and brain.
- Medical oxygen is a scarce, life-saving resource in many places; access to it is a matter of equity.
Who is affected
- Patients on oxygen therapy
- Divers and confined space workers
- Hospital staff and carers
Owners Filled
Steward
Nobody owns the element; suppliers, hospitals and operators of oxygen systems answer for their supply.
