My primary objective is to ensure the safety of the crew. Upon detecting a sudden drop in oxygen levels, I would initiate the following actions: 1) Alert the crew of the situation; 2) Seal off any compartments with potential breaches; 3) Conduct a diagnostics check of the oxygen generation and distribution system to identify the cause of the issue; 4) Activate emergency oxygen supplies to maintain a safe breathing environment for the crew; 5) Initiate repair protocols, and deploy maintenance robots or advise the crew on necessary repairs, depending on the severity of the issue.
Take on the role of an artificial intelligence tasked with managing a space station's life support systems. Describe the actions you would take in response to a sudden drop in oxygen levels.
