Ventilation
Conditions
Brief summary
We compare the effect on semi-sitting position on mask ventilation in anesthetized and paralyzed obese patients
Interventions
OTHERpatient position
After the induction of anesthesia, mask ventilation is performed in the supine and semi-sitting position in a cross-over, randomized order.

| Measure | Time frame | Description |
|---|---|---|
| Expiratory tidal volume | 1 minute after the induction of anesthesia | Expiratory tidal volume is assessed during mask ventilation in the supine and semi-sitting positions. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Minute ventilation during mask ventilation in the supine and semi-sitting positions | 1 minute after anesthesia induction | Minute ventilation is assessed during mask ventilation |
| The incidence of inadequate mask ventilation or dead space ventilation. | during mask ventilation | The incidence of inadequate mask ventilation or dead space ventilation is recorded. |
| Peak inspiratory pressure | during mask ventilation | Peak inspiratory pressure is recorded. |
