The role of peak inspratory flow rate for inhaler choice in patients with asthma and COPD

Conclusion: Surehaler permitted significantly higher flow rates more than other dry powder inhalers, especially in moderate and sever stages of Asthma and COPD (Lower inner resistance).

📌 3 Key Takeaways

🎯

Objective & Hypothesis:Objective: The aim this study was first to measure inspiration current velocity of patients astma and COPD with pulmonary function tests (PFT) and in check apparatus and second to compare it with current velocity at different dry powder inhaler.

📊

Key Findings & Data:Methods: Seventy-four patients with different degree of COPD and 41 patients with astma were included in the study.

💡

Conclusion & Impact:Conclusion: Surehaler permitted significantly higher flow rates more than other dry powder inhalers, especially in moderate and sever stages of Asthma and COPD (Lower inner resistance).

Abstract

Objective: The aim this study was first to measure inspiration current velocity of patients astma and COPD with pulmonary function tests (PFT) and in check apparatus and second to compare it with current velocity at different dry powder inhaler. Methods: Seventy-four patients with different degree of COPD and 41 patients with astma were included in the study. In-check apparatus and PFT were performed at the same time to patients. Flow rates which occured for Discus (D), Turbohaler (T), Autohaler (A), and Surehaler (S) were recorded and PIF (in-PIF) without inspiratory restriction was measured with in-check apparatus. Results: The current velocity at PFT is harmony with the current velocity with in check apparatus.The reduction of FVC and PIF at asthma and COPD is seen corelated with the degree of the disease. Conclusion: Surehaler permitted significantly higher flow rates more than other dry powder inhalers, especially in moderate and sever stages of Asthma and COPD (Lower inner resistance).

Özet

Amaç: Bu çalışmada farklı şiddetlerdeki Astım ve KOAH lı hastaların solunum fonksiyon testi ve in-check cihazi ile inspratuar akım hızlarını ölçmek ve farklı kuru toz inhaler kullanımında oluşan akım hızlarını karşılaştırmaktır. Gereç ve Yöntem: Çalışmaya farklı şiddetlerdeki 74 KOAH lı ve 41 Astımlı hasta alındı. Hastalara eş zamanlı SFT ile farklı kuru toz inhalerlerin iç dirençlerine ve oluşturdukları akım kısıtlamalarına göre dizayn edilmiş İn-check cihazı uygulandı. Bulgular: İn-check cihazında ölçülen Peak inspratuar akım hızlarının SFT de ölçülen ile uyumlu olduğu görüldü. Astım ve KOAH da FVC, ve PIF daki kısıtlamaların, hastalığın şiddeti ile korele olduğu gözlendi. Sonuç: Surraler astım ve KOAH in özellikle ağır ve orta şiddetlerinde diğer kuru toz inhalerlerden anlamlı olarak daha yüksek akım hızlarına izin verdiği yani daha düşük iç dirence sahip olduğu görüldü.
