Key result
Active cycle breathing technique significantly improved Forced Expiratory Volume in 1 second (2.69 vs 2.57 L, p=0.05) and chest expansion (107 vs 104 cm, p=0.047) compared to conventional therapy in post-CABG patients.
Why the study?
The effects of active cycle breathing technique on pulmonary function in post coronary artery bypass graft surgery patients remained to be determined.
Does the active cycle of breathing technique improve pulmonary function and chest expansion in post-CABG patients compared to conventional physical therapy?
RCT (n=40)
Single-blind
Sealed envelope method
No
Does the active cycle of breathing technique improve pulmonary function and chest expansion in post-CABG patients compared to conventional physical therapy?
Absolute Event Rate: 2.69% vs 2.57%
p-value: p=0.05
The addition of the active cycle of breathing technique to conventional chest physiotherapy significantly improves FEV1 and chest expansion in post-CABG patients during phase I cardiac rehabilitation.
ACBT may warrant integration into post-CABG rehab; extends RCT evidence for physiotherapy in cardiac surgical recovery.
Objectives: To determine effects of active cycle breathing technique (ACBT) on pulmonary function of post coronary artery bypass Graft surgery (CABG) patients. Methodology: A randomized control trial was conducted with a sample size of 40 post CABG patients from September 2018 to January 2020. Vitally stable both male and female post CABG Consecutive patients of age bracket 30-65 years were included in study. Two groups were made by randomization through sealed envelope method. Patients in ACBT group (n=20) did ACBT whereas control group (n=20) performed deep breathing exercises along with conventional treatment. Lung volumes & capacities, vitals (heart rate, respiratory rate, oxygen saturation and blood pressure) and chest expansion were assessed at baseline and on fifth post-operative day. Data was analyzed using SPSS version 21. Results: Out of all the 40 patients 26 (65%) were males and 14 (35%) were females with the mean age of 53±7.9 years in conventional and 56±5.9 years in group performing ACBTs. There was significant improvement in Forced Expiratory Volume (FEV1) and chest expansion (p≤0.05) of ACBT group. However, within group analysis revealed significant improvement in all parameters of both groups (p<0.01). Conclusion: Active cycle breathing technique has beneficial effects in improving FEV1 and chest expansion as compared to traditional physical therapy in post CABG patients during phase I of cardiac rehabilitation.

Hussain et al. (2022) conducted an RCT in Post coronary artery bypass graft (CABG) surgery (n=40). Active cycle of breathing technique (ACBT) vs. Conventional physical therapy treatment plus deep breathing exercises was evaluated on Forced expiratory volume in 1st second (liters) at 5 days (p=0.05). Active cycle breathing technique significantly improved Forced Expiratory Volume in 1 second (2.69 vs 2.57 L, p=0.05) and chest expansion (107 vs 104 cm, p=0.047) compared to conventional therapy in post-CABG patients.
