4.2 Understanding the Risk Indicator

The device features a color-coded risk indicator to help you quickly assess your lung function control condition. This indicator is based on your personalized expected PEF value.

• Green Zone (Above 80% of Expected PEF): Indicates good control. Your lung function is within a healthy range.
• Yellow Zone (50% – 80% of Expected PEF): Caution is needed. Your airways may be narrowing. Monitor closely and follow your healthcare provider's advice.
• Red Zone (Below 50% of Expected PEF): This is an emergency level. Contact your doctor or emergency services right away.

Note: No risk indicator will be displayed on the device without properly setting the expected value.
