MAP vs. NAP: The Impact of Mechanical Ventilation on Hemodynamics

Please note: exam questions are subject to change.

1. In Positive Pressure Ventilation (PPV), increased intrathoracic pressure during inspiration primarily leads to: Enhanced venous return Decreased venous return Increased cardiac preload Improved right ventricular output
2. How does Mean Airway Pressure (MAP) affect preload? MAP reduces preload by applying pressure on the heart MAP increases preload by enhancing venous return MAP has no impact on preload MAP decreases afterload instead of preload
3. Increased afterload is typically caused by: Improved venous return Compressed or restricted blood vessels Reduced Mean Airway Pressure (MAP) Decreased pulmonary resistance
4. Which of the following is considered the most stable and commonly safest method to raise MAP? Raising PIP or volume Shortening rise time Raising PEEP Increasing respiratory rate
5. If CPAP levels are not high enough to maintain an "open lung" state, the lung may be at risk for: Hypoventilation and bronchospasm Atelectotrauma and volutrauma Reduced cardiac output and venous return Improved oxygen saturation
