Comparison of Manual and Mechanical Ventilation During Intensive Care Unit Transport Following Cardiac Surgery: Impact on Oxygenation, Ventilation, and Hemodynamic Stability
Authors' conclusion
In patients who have undergone cardiac surgery, hypotension occurred more frequently in the BVM group than in the mechanical ventilation group during transport to the ICU. However, oxygenation and ventilation parameters were comparable between the two groups.
Study context
- Population
- Patients after cardiac surgery transported to the intensive care unit (ICU), single-center tertiary academic hospital, September 2023–August 2024
- Participants
- 48 patients
- Comparison
- Bag valve mask (BVM) vs Mechanical ventilation
Methodological detailsprospective, single-blinded, single-centre
- Prospective
- Single-blinded
- Single-centre
Primary result
As reported in the abstract
Oxygenation and ventilation (% change in PaO2/FiO2 ratio and PaCO2 pre- vs post-transport)
- BVM vs Mechanical ventilation: P = 0.133
- BVM vs Mechanical ventilation: 0.902
Safety
| Outcome | P value |
|---|---|
| Hypotension (>10% decrease in MAP) · during transport to ICUSignificantly more frequent in the BVM group | P = 0.00986 |
