Philips Respironics Peak Flow Personal Flow Meter

User-friendly technique:

• A folding handle keeps your hand away from the gauges; it also helps as a technique to get a correct reading.

Colors define three measurement zones that help you see if you or your child's condition is stable or worsening.

Set the device to measure your personal interval:

• The healthcare professional can set the indicators with colors to represent the following personal best peak flow percentages: green zone 80 – 100% personal best; yellow zone 50 – 80% of personal best value; red zone 50% or less of personal best value
