“…Both regimens were equally safe and effective and it was suggested that the self-applied technique of HFCWO would provide an adequate alternative to conventional physiotherapy. This concurred with a review of the literature published in the same year [37]. KLUFT et al [38] also compared HFCWO with conventional/standard chest physiotherapy and, as more sputum was expectorated during treatment when HFCWO was used, they also concluded that HFCWO was at least as effective.…”

Techniques for augmenting, when necessary, the normal mucociliary and cough clearance mechanisms of the lungs are not new, but, in more recent years, techniques have been developed which are effective, comfortable and can be used independent of an assistant in the majority of adolescents and adults.Postural drainage with chest clapping and chest shaking has, in most parts of the world, been replaced by the more effective techniques of the active cycle of breathing, autogenic drainage, R-C Cornet1, Flutter1, positive expiratory pressure mask, highfrequency chest wall oscillation and intrapulmonary percussive ventilation. Glossopharyngeal breathing is being considered again and is often a useful technique for increasing the effectiveness of cough in patients with tetraplegia or neuromuscular disorders.The evidence in support of these techniques is variable, and the literature is confusing and conflicting. There may or may not be significant differences among the techniques in the short or long term. Many of the regimens now include the forced expiratory manoeuvre of a "huff" and this has probably increased the effectiveness of airway clearance. If objective differences are small, individual preferences and cultural influences may be significant in increasing adherence to treatment and in the selection of an appropriate regimen or regimens for an individual patient.

“…YFGDO uygulaması sırasında artan hava akışı-mukus etkileşiminin mukus viskoelastisitesini azaltması, ekspiratuar hava akışı sağlaması ve siliyer aktivitenin arttırılması havayolu temizliğini sağlayan fizyolojik mekanizmalardır (20,21). YFGDO aletleri, hava atımlarını sinüzoidal veya triangular dalga formlarıyla meydana getirirler (22,23).…”

Amaç: Kistik fibrozisli (KF) hastalarda kısa süreli yüksek frekanslı göğüs duvarı ossilasyonu (YFGDO) uygulamasının etkilerinin ve kişisel kullanımının değerlendirilmesiydi.Yöntemler: Klinik olarak stabil 9 KF'li hasta (yaş ortalamaları 15.0±3.9 yıl) çalışmaya alındı. YFGDO uygulaması 15 seans boyunca günde bir kez 30 dakika süre ile yapıldı. Tedavi öncesi ve sonrası hastaların solunum fonksiyonları ve fonksiyonel egzersiz kapasiteleri (6 dakika yü-rüme testi) değerlendirildi. Hastaların daha önce uyguladıkları tedavi yöntemleri ve uygulanan yöntemler arasındaki tercihleri, görsel analog skalasına göre YFGDO uygulaması memnuniyet düzeyleri ve tedavinin etkinliği hakkındaki görüşleri kaydedildi. Sonuçlar:Tedavi öncesi ve sonrası solunum fonksiyon testi ve 6 dakika yürüme testi mesafesinde istatistiksel olarak anlamlı bir fark bulunmadı (p>0.05). Bununla birlikte, tedavi sonrası hastaların zorlu vital kapasitenin %25-75 akım hızı yüzde değerlerinde anlamlı bir artış saptandı (p<0.05). Görsel analog skalasına göre, olguların YFGDO tedavi memnuniyeti 6.7±3.2 puan, uygulamanın etkinliği ise 6.9±3.3 puandı. Hastaların % 87.5'i, YFGDO yöntemi-ni, havayolu temizleme teknikleri arasında ilk tercih sırasına aldı.Tartışma: YFGDO uygulaması sonrası, solunum fonksiyonları ve fonksiyonel kapasite korunmaktadır. YFGDO olgularımız tarafından tercih edilen, memnun kalınan ve etkin bulunan bir yöntemdir. Bu konuda çok sayıda olguda ve uzun dönem yapılacak yüksek kaliteli randomize kontrollü çalışmalar, YFGDO'nun havayolu temizleme teknikleri içindeki önemi hakkında fizyoterapistlere ve hastaların ailelerine ışık tutacaktır.Anahtar kelimeler: Kistik fibrozis; solunum terapisi; solunum fonksiyon testleri RESEARCH ARTICLE THE EFFECTS OF HIGH FREQUENCY CHEST WALL OSCILLATION IMPLEMENTATION IN PATIENTS WITH CYCTIC FIBROSIS ABSTRACTPurpose: The aim of the study was to evaluate the effects and personal use of short-term high frequency chest wall oscillation (HFCWO) implementation in patients with cystic fibrosis (CF). Methods:Nine clinically stable patients with CF (mean age:15.0 ± 3.9 years) were enrolled in the study. HFCWO implementation was performed 15 sessions, daily for 30 minutes. Respiratory function and functional exercise capacity (6-minute walk test) of patients were assessed before and after treatment. Patients' treatment methods that applied previously and preferences between the applied methods, their opinions about satisfaction level and the treatment efficacy of HFCWO implementation according to the visual analog scale were recorded.Results: There were not statistically significant difference in pulmonary function test and 6-minute walk test distance before and after treatment (p>0.05). However, there was a significant increase in flow rate of 25-75% of vital capacity -percent values of patients after treatment (p<0.05). According to visual analogue scale, HFCWO treatment satisfaction of patients was 6.7±3.2 points, implementation efficacy was 6.9±3.3 points. HFCWO method was first preference among airway clearance tech...

“…High frequency chest wall oscillation (HFCWO) causes air to move into and out of the lungs at high velocity but short duration [33]. The high flow of air shears mucus from airway walls, decreases the viscoelasticity of mucus, and promotes cephalad movement of secretions.…”
