Objective:
The aim of this study is to evaluate the usefulness of Free Running Asthma Screening Test (FRAST) as a method that may help the diagnosis of exercise-induced bronchospasm (EIB) in children from a rural area and to compare the results with their history of asthma.
Methods:
A FRAST challenge took place at 9 schools. It lasted for 6 minutes and pupils performed it properly with the help of an athlete. The best out of three Peak Expiratory Flow Rate (PEFR) efforts was recorded before and after challenge, using a mini-Wright peak-flow-meter. A more than 15% drop in PEFR was considered an indication of EIB. A questionnaire defining asthmatic symptoms had been distributed and already completed by their parents.
Results:
The exercise was successfully performed by 268 children. Eleven children presented a fall of PEFR of at least 15%, five or ten minutes after the exercise; among these, only three boys had a history of asthma, while the remaining 8 children were undiagnosed. No difference regarding age, gender or locations' altitude was found.
Conclusion:
FRAST can be of great use in the diagnosis of EIB in areas that lack proper tools and specialized personnel. A poor correlation between self-reported symptoms and the results of exercise challenges was confirmed.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

Asthma-IV: Diagnostic and Management
Clinical Assessment for Asthma:
This is the first step in diagnosing and managing asthma. It includes:
Assessment of Respiration
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...
Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
