Abstract

Aim: In this study, the aim is to determine the effects of BIPAP on alveolar gas exchange and haemodynamics over BIPAP + PSV mode in acute respiratory failure. Material and method: After sedation, 50 patients with acute respiratory failure were ventilated. BIPAP was preferred for first six hours and 10 cmH20 PSV was added on BIPAP for the second six hours. Mean arterial pressure (MAP), heart rate (HR), inspiratuar pressure (Pinsp), peak pressure (Ppeak)' Pato pressure (Ppiat0), mean pressure (Pmean), minimum pressure (Pmjn),intrinsic PEEP (PEEP,-,) total minute volume (MVtop), spontaneous minute volume (MVspo) and ratios, total frequencies (ftop), spontaneous frequency (fspo) and ventilatuar frequency (fmek)' inspirium ve expirium tidal volumes (VTinsp, VTeksp), resistans, complians, arteriel blood gases values, Fi02 values and Horovitz Index (Pa02/Fi02) were recorded at, Tl: initiation of ventilation, T2: end of the BIPAP ventilation, T3: end of BIPAP + PSV ventilation. Results: There was no statistically difference in haemodynamic data, Ppeak, MVtop, VTinsp, VTeksp, airway resistance, compliance, PaC02, Sa02 ve Pa02 values. The increase in spontaneous respiratory rate and decrease in Pinsp with BIPAP + PSV mode was statistically significant (p<0.05). Arterial blood gas analysis with BIPAP + PSV ventilation, Fi02 levels were reduced while Horovitz index values were increased (p<0.05). Conclusion: BIPAP and adding 10 cmHzO PSV provide positive effects on oxygenation. We think that the effects of this kind of hybrid ventilation should investigate at homogenous sub¬groups and long term ventilation.

Özet

Amaç: Bu çalışmada akut solunum yetersizliğinde, BIPAP ve BIPAP + PSV modlarının alveolar gaz değişimi ve hemodinami üzerine etkilerinin karşılaştırılması amaçlandı. Gereç ve Yöntem: 50 olgu, sedatize edilerek, ventilator ile solutuldu. Olgulara ilk 6 saat BIPAP, sonraki 6 saat BIPAP + 10 cmH20 PSV uygulandı. Veriler; ortalama arter basıncı (OAB), kalp atım hızı (KAH), inspiratuar basınç (PİnSp), pik basınç (Ppeak), plato basınç (Pplato), ortalama basınç (Pmean), minimum basınç (Pmin), PEEPi, toplam dakika hacmi (MVtop), spontan solunum dakika hacmi (MVspo) ve oranları, toplam solunum frekansı (ftop), spontan solunum frekansı (fspo) ve mekanik ventilasyon frekansı (fmek), inspiryum ve ekspiryum soluk hacimleri (VTinsp, VTeksp), rezistans, kompliyans, arteriyel kan gazı değerleri, Fi02 düzeyleri ve Horovitz İndeksi (Pa02/Fi02) yapay solunumun başlangıcında (Tl), ilk 6 saat BIPAP ventilasyonu sonunda (T2) ve sonraki 6 saat BIPAP + 10 cmH20 PSV uygulamasının sonunda (T3) kaydedildi. Bulgular: Olguların hemodinamik verileri, Ppeak, MVtop, VTinsp, VTeksp, havayolu rezistansı; kompliyansı, PaC02, Sa02 ve Pa02 değerlerinde istatistiksel olarak anlamlı fark bulunmadı. BIPAP + PSV ventilasyonu ile Pinsp azalırken, Pmean, spontan solunum sayısı ve toplam spontan dakika hacim artışı anlamlıydı (p<0.05). Arteryel kan'gazı analizinde, BIPAP + PSV ventilasyonu ile olguların Fi02 düzeyleri azalırken, Horovitz indeksi değerleri arttı (p<0.05). Sonuç: BIPAP modunun ve 10 cmH20 PSV eklenmesinin oksijenizasyonu olumlu etkilediği sonucuna ulaşıldı. Bileşik ventilasyonun homojen alt gruplarda ve uzun süreli ventilasyonda etkilerinin çalışılması gerektiğini düşünüyoruz.
