Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Asthma is a complex condition that can impair not only the child's physical growth but also his optimal functional capacity and performance. Buteyko Breathing Technique (BBT) is an exercise designed to regulate the breathing process. The Buteyko technique also proposes lifestyle changes beyond breathing, including diet, allergy avoidance, and stress control. This study aims to evaluate the effect of the Buteyko breathing technique on asthma severity control among school-age children. In Egypt, this technique was applied through five studies, four among adult patients and only one among children. At Mansoura University, only one study was conducted among adult patients, and no studies were conducted among children. To fulfill this knowledge gap, it is necessary to study the effect of this technique on asthma severity control among school-age children. This study will use the Childhood Asthma Control, Peak Expiratory Flow Rate, and Control Pause tests to evaluate the children's asthma severity control.

Methods

Research design:

A quasi-experimental design, one group pre and post-test will be used to conduct this study.

Study setting:

The study will be conducted at the out-patient clinics of Mansoura University Children Hospital (MUCH), which provides health services to children cases from the Dakhlia governorate and Delta region as asthmatic children routinely come to follow up on their condition with their parents.

Subjects:

The sample size cannot be calculated as there is no specific annual statistical report about the admitted asthma condition to the sensitivity clinic, so a convenient sample of asthmatic school-age children who fulfills the following criteria through the data collection period (3 month) will be recruited.

Ethical considerations:

* Ethical approval will be obtained from the Research Ethics Committee. Then official permission will be obtained from the hospital administrative authority to collect data and conduct the study.
* Participants and their parents will be informed that participation in this study is voluntary, and they have the right to accept or refuse participation in the study. Written informed consent will be obtained from the children and their parents, who will accept to participate in the study after providing them with a complete and detailed description of the study including the purpose and benefits. Participants will be informed that their personal data will be kept confidential. All information taken from participants will be protected.

Data collection tools: Data will be collected using the following three tools.

I. Tool one; Structured interview sheet for children and their mothers.

It consisted of two parts as follow:

* Part one; school age child's Biodemographic and clinical data This part was developed by the researcher after reviewing relevant literatures (Chen, et al, 2016; Kuti, \& Omole, 2017), and modifications of study supervisors.
* Part two; Childhood Asthma Control Test(C-ACT)

II. Tool two; Peak Expiratory Flow Rate (PEFR) test

Steps of PEFR assessment:

\- Determining the percentage of PEFR, which equals: \[PEFR% = (measured PEFR \\ Predicted PEFR) ×100\].

\- The predicted PEFR will be calculated using the child's height by the following formula: \[Predicted average PEF \[L/min\] = (Body height \[cm\] x 5.3) - 433\] (Kopač, 2017).

* The actual PEFR will be estimated by:

1. Each child will be studied in the direct sitting posture.
2. The disposable mouthpiece will be calibrated to the peak flow meter mouthpiece.
3. The pointer will be shifted to zero.
4. The child will be told to maintain (horizontally) the level of the peak flow meter and to keep his fingers away from the pointer.
5. The child will be asked to take a deep breath and tightly close his lips around the plastic disposable mouthpiece.
6. The child will be ordered to puff as much as possible.
7. The child will be told to note that it is determined by the velocity of his puff.
8. The readings will be taken.
9. The pointer will be shifted to zero again.
10. This will be replicated three times by each child, and the highest reading will be recorded. ( American Lung Association 2019).

III. Tool three; Control Pause Test (CP) adopted from Buteyko Clinic International (2014).
* Evaluating the Control Pause Breathing test using the following steps:

1. The child will be instructed to sit and take a relaxed posture in a vertical chair, relax his shoulders and lean his lower back against the back of the chair.
2. Until conducting CP, the child will be told to avoid alternate breathing; the child will be asked to take a small breath in (two seconds), a small breath out (three seconds), and clutch the nose with empty lungs but not too clear on the 'out-breath. To prevent air from escaping through the airways, clutching the nose is necessary.
3. The researcher will estimate how many seconds the child can continue safely before breathing in again,
4. The child will be told to hold their breath until the first need to breathe in is felt.
5. The first intake of breath after the CP should be no higher than the breath before taking the measurement; the child should not hold the breath for too long as this could lead the child to take a major breath after measuring the CP.

Study intervention:

A. The preparatory phase:

* A learning booklet and a story will be prepared by the researcher in a simple Arabic language to meet the mother's needs and motivate the children after reviewing the articles and literature. The data collection instrument (children's peak flow meter with the number of disposable plastic mouthpieces, measuring tape, weight scale, stopwatch, disinfectant alcohol, and pen) will be prepared by the researcher.
* The content validity of the study tools will be assessed and revised by a jury that involved a panel of five experts in the Faculty of Nursing at Mansoura University. The tool will be revised for clarity, relevancy, applicability, comprehensiveness, understanding, and easiness for implementation, and modifications will be made according to their opinions. The content reliability of the study tools will be tested by using Cronbach's alpha test.

B. Exploratory phase:

1. Pilot study A pilot study will be carried out on four cases to evaluate the clarity, feasibility, and applicability of the study tools, educational booklet, and story. In addition, identifying the possible obstacles that might hinder data collection and overcoming it. These subjects won't be included in the study sample.
2. Fieldwork

* Data collection will be extended over three months; the researcher will attend two days per week in the allergy outpatient clinic from 9.00 am to 2.00 pm, and each child will take the Buteyko educational program over four weeks, one session each week.
* Before the intervention: at the first-week session (1-W):

1- An individualized interview with the children and the caregiver will be conducted at the beginning of the first-week session, where the parent will sign the informed consent. Then All the study tools (C-ACT, PEFR, and CPT) will be assessed before the intervention to determine the baseline data.
* During the intervention: at first, second, third, and fourth-week sessions (1-W, 2-W, 3-W, 4-W):

1. Demonstrating Buteyko Breathing Technique (BBT) until the child adequately understands its steps. Starting with the steps of the first-week session then, adding the newly learned steps of each following week accordingly (1-W, 1+2-W, 1+2+3-W, 1+2+3+4-W) as follows:

Week one exercise:
* Starting with nose breathing
* Relaxed breathing technique
* The control pause technique
* Advising of an hour of taping
* Daily nose-breathing walk technique
* Managing medication instruction
* Buteyko education about how to stop cough

Week two exercise
* Extended pause technique
* How to avoid colds and flu
* Reduced breathing technique
* Night-time nose breathing instruction

Week three and four
* Very reduced breathing technique
* Lifestyle, diet, and sleep modification
2. Evaluating the BBTpractice of the children and their parents. The child will be asked to redemonstrate the Buteyko steps until he has well-practiced them. They will be instructed to practice this technique at home regularly. Parents will also be instructed to help their children to practice twelve repetitions of the Buteyko steps per day: four repetitions in the morning, four repetitions in the afternoon, and four repetitions in the evening, and to record the number of steps done by their children in their Buteyko Steps Diary. Finally, they will be instructed to follow the modified lifestyle.
3. Following each weekly BBT- educational session, each child will be Evaluated for PEFR and CPT to follow up on the child's prognosis (2-W, 3-W).
* After the intervention: at the fourth-week session (4-W):

1. At the end of the final session, the child will be evaluated for C-ACT, PEFR, and CPT to evaluate the post-test.
