Comparison of the Impact of Three Programs of Inspiratory Muscles.

"The physiotherapist perform the IMT using the threshold IMT inspiratory muscle trainer, connected to the intubation tube. He manage the resistance to the higher resistance tolerated by the patient in a set of 6 breaths. Participant repeats 4 sets of 6-10 breaths with 2 minutes of resting with mechanical ventilation between each set.~This treatment is made twice a day, 7days per week from inclusion to extubation exept if Glasgow score is under 8, hyperthermia more than 39°c, haemodynamic's instability, or hypoxemia( PaO2/FiO2\<150)."

"The physiotherapist perform the IMT using the threshold IMT inspiratory muscle trainer, connected to the intubation tube. He manage the resistance to 30% of the Maximal Inspiratory Pressure initially recorded the day of the inclusion. Participant breaths against this resistance during 5 minutes. The resistance is daily increased of 10 % to the higher tolerated.~This treatment is made twice a day, 7days per week from inclusion to extubation exept if Glasgow score is under 8, hyperthermia more than 39°c, haemodynamic's instability, or hypoxemia( PaO2/FiO2\<150)."

"The physiotherapist perform the IMT using the threshold IMT inspiratory muscle trainer, connected to the intubation tube. He manage the resistance at 30% of the Maximal Inspiratory Pressure of the day for the first set of 20 breaths with a resistance 's increasment of 10% at each set. Participant repeats 4 sets of 20 breaths with 2 minutes of resting with mechanical ventilation between each set.~This treatment is made twice a day, 7days per week from inclusion to extubation exept if Glasgow score is under 8, hyperthermia more than 39°c, haemodynamic's instability, or hypoxemia( PaO2/FiO2\<150)."
