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

Outcome Measures

Primary Outcomes (1)

  • Arterial Blood gas Parameters (PaO2 and SaO2)

    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.

    Baseline 5 days pre-surgery , Immediately after the surgery within 48 hours , and through study completion an average of 8 days.

Secondary Outcomes (4)

  • Atelactasis

    Baseline 5 days pre-surgery, Immediately after the surgery within 48 hours, and through study completion an average of 8 days.

  • Functional capacity (2- minute walk test)

    Baseline 5 days pre-surgery, and through study completion an average of 8 days.

  • Physical function ICU test - scored (PFIT-s)

    Immediately after the surgery within 48 hours.

  • Mechanical Ventilation duration

    from the end of surgery until successful extubation .

Study Arms (3)

IS

EXPERIMENTAL

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).

Device: Incentive spirometry

IMT

EXPERIMENTAL

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).

Device: Inspiratory muscle trainer

Control group

ACTIVE COMPARATOR

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).

Other: Routine physical therapy

Interventions
