The accuracy of digital indicators shall be +/- ____ % of the operating pressure at which they are used.

The accuracy of digital indicators in medical gas systems is critical for ensuring proper monitoring and safety. The correct specification of +/- 5% of the operating pressure reflects an acceptable range for reliable performance in clinical settings.

This level of accuracy is crucial in healthcare environments where exact pressures are necessary for the safe administration of gases. A 5% accuracy standard allows for slight variations in monitoring without compromising patient safety or efficacy of treatment. Operating pressures can vary for different gases and applications, and having a 5% tolerance helps ensure that any fluctuations do not lead to significant issues during use.

Higher accuracy standards, such as 2% or 3%, might be ideal in certain specialized applications but are not considered necessary in most routine medical gas applications. Conversely, a standard of 10% could introduce significant risks, leading to potential misadministration of gases or inadequate pressure supply, emphasizing why it is essential to adhere to the established guideline of 5%.
