About this study

Physical exercise on a cycle ergometer combine with CPAP as an adjunct to the rehabilitation of hospitalized subjects who will undergo myocardial revascularization will be safe, decrease the length of stay in the ICU, and help maintain functional capacity

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Subjects who have undergone myocardial revascularization surgery
  • An ejection fraction of greater than40%
  • Post operative mechanical ventilation for <12hours
  • No definite diagnosis of chronic obstructive pulmonary disease and asthma

Exclusion criteria

  • With complications in post operative period (e.g., Artial fibrillation, prolonged mechanical ventilation)
  • Hemodynamically unstable patients
  • Intolerance to CPAP(continuous positive airway)mask

Treatment and study plan

Conventional Therapy

Other

Subjects will randomly placed into intervention group and control group . In addition to the physiotherapeutic program standardized by the hospital's team of physical therapists, the intervention group will perform physical exercise on a cycle ergometer with CPAP.

Cycle ergometer combine with CPAP

Other

Physical exercise on a cycle ergometer combine with CPAP will be performed in a single daily session from the second to the fourth postoperative days . The maximum exercise time for postoperative day 2 will be 20 min, and 30 min for the third and fourth postoperative days.

Primary outcomes

  1. Modified Borg scale

    Time frame: 4th day

    The Modified Borg Dyspnoea Scale is most commonly used to assess symptoms of breathlessness. Despite being a subjective measure of exercise intensity, RPE scales provide valuable information when used correctly.

  2. 6 min walk distance

    Time frame: 4th day

    The six minute walking test (6MWT) was developed by the American Thoracic Society and it was officially introduced in 2002, coming along with a comprehensive guideline. The 6 Minute Walk Test is a sub-maximal exercise test used to assess aerobic capacity and endurance. The distance covered over a time of 6 minutes is used as the outcome by which to compare changes in performance capacity

  3. 1 min sit to stand test

    Time frame: 4th day

    Vaidya et al reported that 1-minute STS test is a simple and sensitive test and appears to be a practical, reliable, valid, and responsive alternative for measuring exercise capacity, particularly where space and time are limited

  4. Digital Monovacumeter

    Time frame: 4th day

    The manovacuometer is a simple, quick and non-invasive test which measures the maximal respiratory pressures (MRS).Digital manovacuometer is a reliable and valid instrument for assessing maximum inspiratory pressure and maximum expiratory pressure in healthy subjects
