Ventilation using a hospital ventilator consists of a _________________.

Question

BlackTom AI · Accepted Answer

In hospital settings, mechanical ventilation is delivered by a device that pushes air into the patient's lungs under positive pressure, increasing airway pressure during inspiration. 
Option 1: NEGATIVE PRESSURE PUMP. This would imply a system that creates negative pressure around the chest to draw air in, similar to early iron lung designs; modern hospital ventilators do not operate this way, so this option is incorrect. 
Option 2: POSITIVE PRESSURE PUMP. This describes the standard mechanism of contemporary hospital ventilators, which generate positive pressure to deliver a tidal volume to the patient during inspiration and then allow exhalation. This aligns with current clinical practice for initiating and maintaining mechanical ventilation, making this the correct description. 
Overall, the correct characterization is a positive pressure delivery system, while the negative pressure concept is associated with historical, non-invasive, or specific niche ventilation modalities rather than routine hospital ventilators.
