Conditions

Time of weaning from mechanical ventilation in patients after cardiac surgery.

Interventions

Intervention 1: In the intervention group, patient after cardiac surgery, if whitin 6 hours do not wean

we use of volume assured pressure suppporte ventilation (vaps) and register the time. Intervention 2: In the control group, patient after cardiac surgery, if whitin 6 hours do not wean

we use of pressure suppporte ventilation (psv)( routine method) and register the time.

Treatment - Devices

In the intervention group, patient after cardiac surgery, if whitin 6 hours do not wean

we use of volume assured pressure suppporte ventilation (vaps) and register the time.

In the control group, patient after cardiac surgery, if whitin 6 hours do not wean
