Overview

the goal of this clinical trial is to find out the effect of adding proprioceptive neuromuscular facilitation to inspiratory muscle training on weaning off mechanical ventilation. the main question it aims to answer is is there a significant difference in the effect of inspiratory muscle training combined with PNF on the duration of weaning in the mechanically ventilated ICU patients. researchers will compare effect of (Inspiratory muscle training combined with PNF) to (Inspiratory muscle training) and control group. participants will be mechanically ventilated both sexes patients will be recruited in this study from intensive care unit, their ages older than 18 years. The selected patients will be mechanically ventilated due to respiratory failure and will randomly assigned into three equal groups.

type of study: randomized control trial this study is a prospective interventional study one that will be conducted on ninety three mechanically ventilated patients with respiratory failure of both sexes their ages older than 18 years from intensive care unit and will randomly assigned into three equal groups: 1. intervention group 1:include 31 mechanically ventilated patients will receive inspiratory muscle training along with Conventional rehabilitation program plus medical treatment. 2. intervention group 2: include 31 mechanically ventilated patients will receive inspiratory muscle training combined with proprioceptive neuromuscular facilitation along with Conventional rehabilitation program plus medical treatment. 3. Control group: include 31 mechanically ventilated patients will receive Conventional rehabilitation program plus medical treatment. Instrumentations: A) Evaluation: All the following will be measured for all patients who will participate in this study 1. ICU length of stay. 2. Monitoring: * Mode of ventilation parameters. * Fiao2 * PEEP * Tidal Volume * Respiratory Rate * The Duration and Type of Weaning: * Simple * Prolonged * Difficult * The patient vital signs: * Heart rate * Respiratory rate * Oxygen saturation 3. Maximum inspiratory pressure 4. Laboratory investigation: \- Arterial Blood Gases (ABG): for measurement of Pao2, Partial pressure of CO2 (Paco2), Hco3 and PH 5. Sonar parameters: \- Diaphragmatic excursion. 6. APHACH II score 7. Shallow breathing index. 8. Lung compliance: - Static and dynamic

Interventions

threshold inspiratory muscle training + conventional chest physiotherapyDEVICE

threshold inspiratory muscle training: threshold inspiratory muscle training in addition to conventional chest physiotherapy. The TIMT device will be connected to an endotracheal tube and will be verified to be reliable for inspiratory muscle training. With patient in 45 supine position, he will instructed to exhale slowly, empty the air in the lungs and then inhale deeply and vigorously as fast as possible. The MIP will recorded. The inspiratory resistance is set at 50% of MIP. When the heart rate, pulse oxygen, and respiratory rate are relatively stable during inspiratory training, the inspiratory resistance will be increased by 1-2 cm H2O per day. the resistance will be adjusted every day to be 50% of the new maximum inspiratory pressure then 1-2 cm H2O added. Each patient performed 6 breaths × five sets × twice daily × 5 days/ week. Until patients are weaned from mechanical ventilation.

proprioceptive neuromuscular facilitation + threshold inspiratory muscle training + conventional chest physiotherapyDEVICE

PNF training: in the form of rhythmic initiation technique (RIT) and initial stretch technique (IST) in addition to TIMT plus Conventional Chest Physiotherapy. The RIT performed to teach coordination of motion and to establish the correct breathing pattern. The IST applied to reinforce the strength of inspiratory muscles. Its main aim is to facilitate the initiation of motion . PNF techniques include two sessions per day, 5 days/week until patients are weaned from mechanical ventilation. Including four 90-second manual stimulations each (upper ribs, lower ribs, sternum, and diaphragm). After every stimulation the patient rested for one minute.

Conventional Chest PhysiotherapyOTHER

Conventional Chest Physiotherapy only: two sessions per day, 5 days/week which included Vibration, Percussion, hyperinflation, and suctioning if indicated until patients are weaned from mechanical ventilation.
