6. The intelligent method for using a children's breathing trainer according to claim 5, characterized in that,

Preferably, in step 3, the calculation process of the adaptive algorithm is as follows:

Step 3-1: Calculate the total score of the severity of daily breathing symptoms, S. Question Q1 corresponds to nighttime symptoms, Q2 corresponds to exercise-induced dyspnea, and Q3 corresponds to the use of emergency medications. These questions are specifically used to assess daily breathing stability. The scores of the three questions are directly added together to obtain the total symptom score: S = (Q1 + Q2 + Q3), S range: 0~9 points.

Clinical significance: The higher the score, the greater the need for respiratory system compensation;

Step 3-2: Calculate the symptom suppression coefficient α with a weight of 50%, α = 1−9/S, where S ranges from 0 to 9 points;

The more severe the symptoms, the higher S rises, and the lower α becomes → forcibly reducing the gear level; achieving a negative mapping from symptom severity to gear level;

Step 3-3: Calculate the respiratory efficiency coefficient β with a weight of 30%, β = 1 − R/3/3, where R is the Q4 score of 0~3 points;

The faster the resting breathing, the higher the R value, and the smaller the β value, which leads to a reduction in gear and a forced decrease in training intensity.

Steps 3-4: Calculate the physiological potential coefficient γ with a weight of 20%, γ = (V − Vmin) / (Vmax − Vmin)V, where V is the age-appropriate respiratory volume; where the respiratory volume V follows the Shizgal-Rosa model.

Vmin=9.52, Vmax=17.54; Vmin and Vmax are not completely fixed, but are normalized baseline values in the algorithm. In the gear formula, the actual breathing volume is mapped to the [0,1] interval: when V=Vmin→γ=0, the lung function is the weakest, and when V=Vmax→γ=1, the lung function is the strongest.

The greater the lung function potential, the higher the tidal volume (V), and the greater the gamma (γ) level, the higher the lung function potential. The core principle is that personalized tidal volume parameters are automatically generated for different body weights, which accurately reflect lung function potential.

Weighted design principle: Symptom coefficient α accounts for 50%: ensuring safety first; respiratory efficiency β accounts for 30%: real-time functional constraints; physiological potential γ accounts for 20%: individualized intensity calibration.

Symptom-driven layer: The total symptom score S and the derivation coefficient α are calculated through dedicated questions Q1-Q3. Independent parameter layer: Q4 respiratory rate and Q5 (age and weight) are used as independent inputs. Respiratory efficiency downgrading mechanism: Q4 is converted into R value, and β=1-R/3 is used to realize that the higher the frequency, the lower the level. Weight-tidal volume fitting mechanism: Q5 weight data is used to generate personalized tidal volume V through a piecewise linear formula.

Steps 3-5: Determine the final gear D, D=round(1+5*(0.5α+0.3β+0.2γ)), D: gears 1~6, round D to the nearest integer.
