Conditions

Coronary Artery Bypass Graft (CABG)

Brief summary

This study will be conducted to compare between incentive spirometry verses inspiratory muscle training preoperatively on (ABG) after coronary artery bypass graft surgery. Is there any significant difference of preoperative incentive spirometry verses inspiratory muscle training on Arterial blood gases (ABG) after coronary artery bypass graft surgery? Participants will: Group A (incentive spirometry group ) Group B (Inspiratory muscle trainer group ) for 5 days before operative Group C (control group) and group a , b will have routinely postoperative

Interventions

DEVICEIncentive spirometry

This group will include 15 patients, Incentive spirometry was utilized by the patient with ten breaths, six sets per day for a period of 10 min within patient tolerance in every session for five days with routinely physical therapy program (education and explanation) preoperatively, And postoperatively treatment (breathing treatment, deep-breathing applications, guided coughing, early mobilization).

This group will include 15 patients, each session consisted of 30 minutes of inspiratory muscle training. The patients were trained to use an inspiratory threshold-loading device (Threshold Inspiratory Muscle Training) for five days with routinely physical therapy program (education and explanation) preoperatively, And postoperatively treatment (breathing treatment, deep-breathing applications, guided coughing, early mobilization).

OTHERRoutine physical therapy

15 patients will receive for 5 days routinely physical therapy program (education and explanation) preoperatively, And postoperatively treatment (breathing treatment, deep-breathing applications, guided coughing, early mobilization).

Design outcomes

Primary

MeasureTime frameDescription
Arterial Blood gas Parameters (PaO2 and SaO2)Baseline 5 days pre-surgery , Immediately after the surgery within 48 hours , and through study completion an average of 8 days.Assessment of arterial oxygenation changes by measuring PaO2 and SaO2 . data will be collected at Baseline pre-surgery (5 days ) , Immediately after the surgery (within 48 hours) , and through study completion an average of 8 days. to evaluate the recovery trend and the effectiveness of respiratory interventions.
Numerical rating pain scaleBaseline 5 days pre-surgery , Immediately after the surgery within 48 hours , and through study completion an average of 8 days.Pain Scale for Pain Assessment. data will be collected at Baseline pre-surgery (5 days ) , Immediately after the surgery (within 48 hours) , and through study completion an average of 8 days. to evaluate the recovery trend and the effectiveness of respiratory interventions.

Secondary

MeasureTime frameDescription
Functional capacity (2- minute walk test)Baseline 5 days pre-surgery, and through study completion an average of 8 days.measuring the maximum distance a patient can walk on a flat surface in 2-minutes to evaluate functional exercise capacity.
Physical function ICU test - scored (PFIT-s)Immediately after the surgery within 48 hours.Assessment of physical function in the ICU through four components ( sit -to- stand, marching, shoulder flexion, and knee extension ) Scored (0 - 10).
