BACKGROUND: Airway clearance impairment has a significant impact on self-care and quality of life. Identifying clinical data, nursing diagnoses, and nursing interventions is essential to clinical reasoning and enhancing nursing care. This study aims to map the existing evidence on clinical data, nursing diagnoses, and nursing interventions addressing the nursing focus on \"airway clearance\".
METHODS: Research was conducted based on Joanna Briggs\'s Scoping Review Methodology. We searched four databases for published studies until December 2023.
RESULTS: From the initial 1854 studies identified, 123 were included in the review. The findings highlighted two areas of nursing attention: one related to signs and symptom management, and the other related to education and coping strategies. The data that led to nursing diagnoses were divided into cognitive and clinical data. The nursing diagnoses were mostly related to secretion retention, excessive mucus production, and airway obstruction. The most commonly identified nursing interventions were educational interventions assembled into predesigned education programs rather than patient-tailored programs.
CONCLUSIONS: Findings can add substantial value for systematizing the nursing process related to \"airway clearance\", improving nursing decision-making and care quality. This study was prospectively registered with the Open Science Framework (OSF) on 02 December 2022, with the registration number wx5ze.

BACKGROUND: A mechanical insufflation-exsufflation (MI-E) device is a commonly used tool for airway clearance in children with an ineffective cough. Whereas the device has been shown to have multiple benefits, limited evidence exists regarding parents\' experiences with its home use in the Canadian context. This study\'s objective was to explore the perspectives and experiences of parents who receive service through the IWK Health Centre and use an MI-E device at home with their child.
METHODS: The study used an interpretive description design. Semi-structured interviews, conducted with 9 participants, were audio recorded and transcribed verbatim. Transcripts were analyzed using a reflective thematic process.
RESULTS: Seven mothers and 2 fathers were interviewed. Following analysis, 3 themes were identified: (1) Learning about the MI-E device described participants\' journey from becoming aware of the device to acquiring knowledge and skills about its use; (2) using the device detailed the integral role the MI-E device played in their lives, including decisions around use, and parental role; and (3) changing lives outlined the physical, emotional, and social benefits the device provided to the child and their family.
CONCLUSIONS: Participants provided detailed descriptions of their journey from learning to integrating the MI-E device into their child\'s daily routine and family life. Its multiple associated benefits improved the child\'s and their family\'s quality of life. However, better education on its use was highlighted as a need for both parents and the health care professionals who work with them.

BACKGROUND: High-frequency assisted airway clearance systems combine positive expiratory pressure or oscillatory positive airway pressure with integrated nebulizers to improve the delivery of aerosols and assist with airway clearance. This aerosol study evaluated lung delivery efficiency during positive expiratory pressure and oscillatory positive airway pressure therapy of 2 high-frequency assisted airway clearance/nebulizer systems.
METHODS: Aerosol delivery was evaluated during positive expiratory pressure therapy of 10 cm H2O and oscillatory positive airway pressure therapy of 20 cm H2O with the BiWaze Clear and the Volara high-frequency assisted airway clearance/nebulizer systems. The handset and nebulizer were attached to an anatomic upper-airway model via a mouthpiece and placed into a plethysmograph. A tracheal filter was placed to capture the inhaled aerosol. A vacuum filter entrained fugitive aerosols from the plethysmograph. After nebulization of technetium in 3.0 mL normal saline solution, the components were scanned by using scintigraphy and the decay-corrected radiation counts were referenced to the initial nebulizer technetium charges.
RESULTS: Aerosol delivery during positive expiratory pressure therapy of 10 cm H2O resulted in higher lung deposition with the BiWaze Clear versus the Volara (28 vs 6.2%; P < .001; 95% CI 16.5-27.7), and higher fugitive losses (23.7 vs 2.8%; P = .004) and nebulizer losses (55 vs 3.3%; P < .001) with the Volara than with the BiWaze Clear. Aerosol delivery during oscillatory positive airway pressure of 20 cm H2O resulted in a higher lung deposition with the BiWaze Clear versus the Volara (16.3 vs 7.3%; P = .005; 95% CI 3.3-15) and higher fugitive (22.3 vs 3.8%; P = .02) and nebulizer (58.8 vs 7.2%; P = .004) losses with the Volara. There were no differences at the other locations during testing.
CONCLUSIONS: The BiWaze Clear system showed greater delivery efficiency than did the Volara during positive expiratory pressure and oscillatory positive airway pressure. The high residual nebulizer dose and fugitive aerosol losses through the handset leak valve contributed to the lower delivery efficiency observed with the Volara. The nebulizer type, circuit design, and handset are important factors when targeting effective aerosol delivery to the lungs with high-frequency assisted airway clearance therapy.

Respiratory sequelae are a frequent cause of morbidity and mortality in children with NMD. Impaired cough strength and resulting airway clearance as well as sleep disordered breathing are the two main categories of respiratory sequelae. Routine clinical evaluation and diagnostic testing by pulmonologists is an important pillar of the multidisciplinary care required for children with NMD. Regular surveillance for respiratory disease and timely implementation of treatment including pulmonary clearance techniques as well as ventilation can prevent respiratory related morbidity including hospital admissions and improve survival. Additionally, novel disease modifying therapies for some NMDs are now available which has significantly improved the clinical trajectories of patients resulting in a paradigm shift in clinical care. Pulmonologists are \'learning\' the new natural history for these diseases and adjusting clinical management accordingly.

OBJECTIVE: We aimed to assess the level of knowledge, attitudes and practices regarding airway clearance among nurses and explore the factors affecting the knowledge, attitudes and practices.
METHODS: A questionnaire-based cross-sectional study.
BACKGROUND: Airway clearance is an important method of eliminating excess secretions. In neuroscience nursing, nurses are important executors of airway management, and their knowledge, attitudes and practices can influence the effectiveness of airway clearance.
METHODS: This study was conducted from July to September 2023 in four hospitals in Jiangsu Province, China. A structured questionnaire about airway clearance was designed and used to collect the data. The nurses used this questionnaire to self-rate. The STROBE checklist for cross-sectional studies was followed.
RESULTS: The age, work experience, highest educational attainment and technical title of the nurses can significantly influence their knowledge. The age, highest educational attainment and technical title of the nurses can significantly impact their attitudes. Practice scores were significantly influenced by age, work experience, technical title, whether the nurses had received any training on airway clearance techniques, and whether the department developed procedures for implementing the airway clearance technology. Nurses\' attitudes were significantly associated with knowledge and practice, and there was no significant correlation between knowledge and practice.
CONCLUSIONS: This study showed that age, work experience, highest educational attainment and training were related to knowledge, attitudes and practices. These findings suggest that nursing managers can conduct airway clearance training according to age group, working experience and education level of the nurses.
UNASSIGNED: No patient or public contribution.
CONCLUSIONS: The findings show that the level of knowledge, attitudes and practices related to airway clearance in neuroscience nursing among nurses were acceptable, which means that nurses can better perform airway management on patients. These findings serve as a significant reference for designing an airway clearance education for nurses and meet the needs of nurses in clinical nursing practice.

BACKGROUND: Airway clearance (ACT) and lung volume recruitment (LVR) techniques are used to manage bronchial secretions, increase cough efficiency and lung/chest wall recruitment, to prevent and treat respiratory tract infections. The aim of the study was to review the prescription of ACT/LVR techniques for home use in children in France.
METHODS: All the centers of the national pediatric noninvasive ventilation (NIV) network were invited to fill in an anonymous questionnaire for every child aged ≤20 years who started a treatment with an ACT/LVR device between 2022 and 2023. The devices comprised mechanical in-exsufflation (MI-E), intermittent positive pressure breathing (IPPB), intrapulmonary percussive ventilation (IPV), and/or invasive mechanical ventilation (IMV)/NIV for ACT/LVR.
RESULTS: One hundred and thirty-nine patients were included by 13 centers. IPPB was started in 83 (60 %) patients, MI-E in 43 (31 %) and IPV in 30 (22 %). No patient used IMV/NIV for ACT/LVR. The devices were prescribed mainly by pediatric pulmonologists (103, 74 %). Mean age at initiation was 8.9 ± 5.6 (0.4-18.5) years old. The ACT/LVR devices were prescribed mainly in patients with neuromuscular disorders (n = 66, 47 %) and neurodisability (n = 37, 27 %). The main initiation criteria were cough assistance (81 %) and airway clearance (60 %) for MI-E, thoracic mobilization (63 %) and vital capacity (47 %) for IPPB, and airway clearance (73 %) and repeated respiratory exacerbations (57 %) for IPV. The parents were the main carers performing the treatment at home.
CONCLUSIONS: IPPB was the most prescribed technique. Diseases and initiation criteria are heterogeneous, underlining the need for studies validating the indications and settings of these techniques.

BACKGROUND: Nebulized Hypertonic saline (HS) and positive expiratory pressure device (PEP) are often used in patients with bronchiectasis. We sought to describe the clinical characteristics in patients using HS and PEP, utilizing a large national database registry.
METHODS: Data from the US Bronchiectasis and NTM Research Registry were used in this study. Patients with a diagnosis of bronchiectasis were included. Eligible patients were assigned to one of four mutually exclusive groups: HS only, PEP only, HS & PEP, or no airway clearance or mucoactive agent. Descriptive statistics were computed for the overall study population and stratified by the four groups. One-way ANOVA and chi-square tests were used to test the difference in the means in continuous variables and the association between categorical variables (respectively) across the four groups.
RESULTS: A total of 2195 patients were included. Of those with bronchiectasis and a productive cough, a greater number of patients utilized HS only vs PEP only (17.5 % vs 9.1 %, p < 0.001). Similar association was found in those with Pseudomonas aeruginosa (22.3 % HS only vs 6.5 % PEP only, p < 0.001). There was a higher number of patients who used HS and PEP therapy in combination vs PEP therapy alone (25.0 % vs 9.1 %, p = 0.002), in those with a productive cough.
CONCLUSIONS: In patients with bronchiectasis and a productive cough or Pseudomonas aeruginosa, HS is used more often than PEP alone. There is a need for further analysis to compare these two modalities and explore the factors influencing their utilization.

Impaired respiratory function secondary to acute or chronic respiratory disease poses a significant clinical and healthcare burden. Intrapulmonary percussive ventilation (IPV) is used in various clinical settings to treat excessive airway secretions, pulmonary atelectasis, and impaired gas exchange. Despite IPV\'s wide use, there is a lack of clinical guidance on IPV application which may lead to inconsistency in clinical practice. This scoping review aimed to summarise the clinical application methods and dosage of IPV used by clinicians and researchers to provide guidance. A two-staged systematic search was conducted to retrieve studies that used IPV in inpatient and outpatient settings. MEDLINE, EMBASE, CINAHL, Scopus, and Google scholar were searched from January 1979 till 2022. Studies with patients aged ≥16 years and published in any language were included. Two reviewers independently screened the title and abstract, reviewed full text articles, and extracted data. Search yielded 514 studies. After removing duplicates and irrelevant studies, 25 studies with 905 participants met the inclusion criteria. This is the first scoping review to summarise IPV application methods and dosages from the available studies in intensive care unit (ICU), acute inpatient (non-ICU), and outpatient settings. Some variations in clinical applications and prescribed dosages of IPV were noted. Despite variations, common trends in clinical application and prescription of IPV dosages were observed and summarised to assist clinicians with IPV intervention. Although an evidence-based clinical guideline could not be provided, this review provides detailed information on IPV application and dosages in order to provide clinical guidance and lays a foundation towards developing a clinical practice guideline in the future.

UNASSIGNED: To limit the progression of disease, people with cystic fibrosis (pwCF) perform daily respiratory physiotherapy, which is perceived as the most burdensome routine in managing their condition. The elexacaftor-tezacaftor-ivacaftor (ETI) combination has changed respiratory management.
UNASSIGNED: To investigate how the perceived treatment burden changed in 1 year of treatment with ETI.
UNASSIGNED: Prospective observational study.
UNASSIGNED: Ad hoc questionnaires for the pwCF and for the caregivers of pwCF < 18 years were administered before the initiation of ETI therapy and then at 6-12 months. The Cystic Fibrosis Questionnaire-Revised (CFQ-R) and the Sinonasal Outcome Test (SNOT-22) were administered to explore disease-related symptoms and social limitations. The International Physical Activity Questionnaire was used to determine levels of physical activity. Mixed-effect models were fitted to explore whether the time engaged in respiratory physiotherapy changed during 1 year.
UNASSIGNED: The study included 47/184 pwCF aged 21.4 (5.7) years, who completed 1 year of ETI therapy. At 6 months, time on aerosol therapy was decreased by 2.5 (95% CI -32.9 to 27.8) min/day, time on airway clearance therapies (ACTs) was decreased by 8.8 (95% CI -25.9 to 8.3) min/day, and time for cleaning and disinfecting respiratory equipment was decreased by 10.6 (95% CI -26.5 to 5.3) min/day. At 1 year, gains in time saved were nearly 15 min/day on average. At 1 year, 5/47 (10.6%) pwCF reported that they had discontinued positive expiratory pressure mask.
UNASSIGNED: PwCF on ETI may note less time engaged in their daily respiratory physiotherapy routine. Nonetheless, aerosol therapy, ACTs and maintaining respiratory equipment were still perceived as time-consuming daily activities.
Understanding the challenges of respiratory physiotherapy in individuals with cystic fibrosis using triple therapy: a one-year study.In order to slow down the progression of their disease, people with cystic fibrosis typically do daily respiratory physiotherapy, which they find to be the most challenging part of managing their condition. The elexacaftor-tezacaftor-ivacaftor combination has changed how they manage their respiratory health. We wanted to see how the perceived difficulty of the treatment changed over one year of using elexacaftor-tezacaftor-ivacaftor. We gave questionnaires to people with cystic fibrosis and to their caregivers before they started the triple therapy and again at 6-12 months. We also used two international questionnaires to learn about symptoms and social limitations related to the disease. The International Physical Activity Questionnaire helped us understand their physical activity levels. We used statistical models to see if the time spent on respiratory physiotherapy changed over the year. Our study involved 47 individuals with cystic fibrosis, with an average age of 21 years, who completed one year of elexacaftor-tezacaftor-ivacaftor therapy. After 6 months, time spent on aerosol therapy decreased by 2.5 minutes per day, time on airway clearance therapies decreased by 8.8 minutes per day, and time for cleaning respiratory equipment decreased by 10.6 minutes per day. By the end of the year, they were saving almost 15 minutes per day on average. At one year, 5 out of 47 said they had stopped using the positive expiratory pressure mask. People with cystic fibrosis using elexacaftor-tezacaftor-ivacaftor may find that they spend less time on their daily respiratory physiotherapy routine. However, activities like aerosol therapy, airway clearance therapies, and maintaining respiratory equipment were still seen as time-consuming.

OBJECTIVE: Airway clearance interventions are recommended for people with chronic lung conditions and mucus hypersecretion, but there are few published models of care or descriptions of airway clearance service provision. This evaluation describes a dedicated, physiotherapy-led, community-based airway clearance service in a metropolitan local health network.
METHODS: Retrospective evaluation using existing airway clearance service administrative database.
METHODS: All first referrals to the airway clearance service in a 5-year period (1/1/2017 to 31/12/2021).
METHODS: Available service data grouped into four domains: participant demographics, referral demographics, service provision and outcomes.
RESULTS: Of the 1335 first referrals eligible for inclusion, 1157 (87%) people attended. Bronchiectasis was the commonest condition (n = 649/1135, 49%). A total of 2996 occasions of service (face to face clinic n = 2108, 70%, phone n = 736, 25%, telehealth n = 99, 3%, home visit n = 53, 2%) were delivered. Airway clearance devices frequently prescribed were the Aerobika (525/1157, 45%), bubble-positive expiratory pressure (263/1157, 23%) and the Acapella (127/1157, 11%). On average, initial appointment with the airway clearance service occurred within 36 days of referral and people attended the service three times. Individuals voluntarily completed both pre/post service questionnaires around a third of the time. At least half of responders reported an improvement in respiratory symptom outcome measures consistent with the minimum clinically important difference.
CONCLUSIONS: This evaluation describes an airway clearance service as it exists, providing an example from which airway clearance services can be planned, implemented and improved.
