Coronary artery bypass graft (CABG) is a surgery in which new
routes are created around narrow and blocked coronary arteries that
allow proper flow of blood providing oxygen and nutrients to the heart
muscles. After CABG respiratory therapy is used rationally to inhibit the
post-operative complications.
The removal of respiratory secretions is an important concern
during the rehabilitation phase after cardiac surgery. The ability to
perform deep inspiration and cough effectively, to prevent accumulation
of secretions and improved gas exchange, is adversely affected by pain
and postoperative apprehension associated with changes in lung
mechanics resulting from surgery which eventually can lead to
atelectasis, pneumonia, and increased mortality.
Oscillating PEP (OPEP) therapy (Quake device) provides the
combination of positive expiratory pressure with high frequency
oscillations. It involves breathing with a slightly active expiration against
an expiratory resistance through a device. It’s used for clearance of
excess secretions from the lungs & reducing gas trapping and improving
ventilation of the lungs
The purpose of this research was to evaluate the efficacy of intrathoracic oscillations via quake device on ABG in post CABG patients.
Sixty men patients underwent CABG in the 55-65 age range were
included in this study. They were recruited from 6 October Hospital. All
participants gave informed permission.

Summary 
78
Patients were randomly assigned into 2 equal groups (30 patients
for each group) with pre and post treatment protocol application. Both
treatments were performed once daily from 1st day till 7th day after
operation. Group A (Study group): Thirty men patients were treated by
Oscillatory PEP (Quake device) along with traditional and prescribed
medical treatment. Group B (Control group): Thirty men patients were
treated by traditional treatment along with their prescribed medical
treatment.
Arterial blood gases, sit to stand test and SF-36 questionnaire were
performed before and after treatment protocol application to assess the
patient’s oxygenation status, functional capacity and health-related
quality of life.
The results of this study demonstrated a statistically significant
difference between pre and post treatment values in all measured
variables within quake device group.
Results also revealed a significant difference in the favor of post
treatment on measured variables compared to pre-treatment condition
within control group.
Comparing the two groups using the same measures revealed a
statistically significant difference between them, with the group that
received treatment by Quake device show a greater improvement than
control group.

شمل هذا البحث ستون مريضا بعد اجراء جراحة توصيل الشرايين التاجية تراوحت اعمارهم ما بين خمس وخمسون وخمس وستون عاما تم اختيارهم من مستشفي 6 اكتوبر تم تقسيمهم الي مجموعتين المجموعة ( أ ) تضمنت المرضي الذين تم علاجهم بالوسائل العلاجية التقليدية بالإضافة الي استخدام جهاز (َQuake) والمجموعة (ب) والتي تضمنت المرضي الذين تم علاجهم بالوسائل التقليدية فقط. كلا المجموعتين تلقوا العلاج بشكل يومي ابتداء من اليوم الاول وحتي اليوم السابع بعد اجراء العملية وقد تم تقييم الحالات عن طريق اجراء تحليل غازات الدم واختبار الجلوس ثم الوقوف و تم ملئ استبيان SF 36. التأهيل المبكر باستخدام جهاز (Quake) بعد جراحة توصيل الشرايين التاجية يمكن ان يؤدي الي تحسن في غازات الدم والكفاءة الوظيفية مما ينعكس علي جودة الحياة للإنسان
