Summary

The aim of this study is to evaluate the effect of power breath device on arterial blood gases, diaphragmatic excursion and the 6 min walk test after cardiac valve surgery.

Conditions

  • Heart Valve Diseases

Interventions

OTHER

Power breath plus

Power breath plus use a variable load calibrated spring. It can be adjusted from the lowest load setting (17cmH2O) when training began and increased as the patient breathing muscles adapt and become stronger (maximum load setting 274cmH2O). Use a comfortable chair, preferably straight-back so that the spine is straight at all times during the exercise. patients will be instructed to exhale calmly, followed by a maximal forced inspiration to total lung capacity using a mouthpiece and a nasal clip as an aid to prevent air leaks and will ask to make 10 breaths for 3 sets once daily for 7 days with 2min rest between sets

OTHER

Incrementing the training load

The resistance will be increased incrementally, based on the rate of perceived exertion (RPE) scored by the patient on the modified Borg Scale. If the RPE is less than 5, the resistance of the inspiratory trainer will be increased incrementally by 2cmH2O. The resistance will not change if the level of perceived exertion is rated from 6 to 8, and the resistance will be decreased by 1 to 2 cmH2O if the level of perceived exertion is rated 9 or 10.

OTHER

Diaphragmatic breathing exercises

Training by using incentive spirometer: * Loosen any tight clothing, especially around neck. * Each patient will be instructed to sit upright with placing incentive spirometer at the same level of his mouth to promote optimal lung expansion while using the spirometer. * The patient will be instructed to exhale letting all the breath out. * patient will asked to close the lips around the mouthpiece of the spirometer. * patient will be instructed to inhale slowly, breathing in until unable to do any more, this would raise the balls to the top of the column. * patient will be asked to hold the breath as long as possible (at least five seconds) then exhale slowly. * Session will be in the form of 30 times in sets, each set consist of 5-6 repetitions with rest 1 minute between sets. * Intensity of exercise will be increased by increasing time of session, time of holding the breath and numbers of repetitions according to patient's status.
