What is the minimum safe residual pressure in an oxygen tank?

100 psi
150 psi
200 psi
250 psi

The correct answer is: 200 psi

The minimum safe residual pressure in an oxygen tank is 200 psi. This value is established to ensure that sufficient oxygen remains in the tank for safe operation and to prevent running out of oxygen in emergency situations. Having a residual pressure of at least 200 psi indicates that the tank contains a usable amount of oxygen for patient care. Maintaining this level is critical for first responders, as running low on oxygen can hinder effective treatment of patients who require supplemental oxygen. By adhering to these guidelines, responders can ensure that they are always prepared to provide the necessary care during emergencies. The values lower than 200 psi would indicate that the tank is nearing depletion and may not provide adequate oxygen for treatment, which is why they do not meet the safety standards required for effective emergency response.
