Andet: Conventional ventilator
30 minutes of non-invasive ventilation was performed with conventional ventilator.The order of the procedures was determined by randomization.
|
A ventilator designed for invasive ventilation was used has mode non-invasive ventilation with leakage compensation (50% of the predetermined tidal volume).
A ventilator was used designed for non-invasive ventilation has an algorithm that calculates the loss of pressure and automatically compensates for leak

Andet: Specific ventilator
30 minutes of non-invasive ventilation was performed with specific respirator.
The order of the procedures was determined by randomization.

Tidsramme |
|---|---|---|
|
Variability of heart rate front the use of noninvasive ventilation in two different ventilators in patients after cardiac surgery, measured by Polar RS800 CX.
Tidsramme: 3 hours
|
The autonomic variables evaluated are: standard deviation of all normal RR intervals recorded in a time interval (SDNN); standard deviation of the mean of normal RR intervals every 5 minutes at a time, expressed in milliseconds (SDANN); percentage of R-Ri with adjacent difference of duration greater than 50 milliseconds (pNN50) and the square root of the average squared difference between the adjacent R-Ri normal in a period of time, expressed in milliseconds (rMSSD).
All variables will be assessed by Polar RS800CX
