1 - the expected reading: which is determined by age, gender, length of the patient, where this reading is different from one patient to another.
2 - reading in the clinic: which is measured by the device maximum blowing capacity 3 times and take the highest reading in the clinic.
3 - The best reading: The highest reading reaches the patient can be identified as follows:
- If reading the clinic is very close to the expected reading, this is the best reading of the patient.
If reading the clinic is far from the expected reading, the patient can be given a table where he reads two readings per day for a week (morning and evening) and bring the table after that, where the highest reading during that week is taken as the best reading.
