Which device uses oxygen under pressure to deliver artificial ventilations?

• A. Automatic Transport Ventilator (ATV)
• B. Bag-Valve Mask (BVM)
• C. Flow-Restricted, Oxygen-Powered Ventilation Device (FROPVD)
• D. Continuous Positive Airway Pressure (CPAP)

Answer: (C)

The correct choice is a Flow-Restricted, Oxygen-Powered Ventilation Device (FROPVD) because this type of device is specifically designed to deliver positive pressure ventilation using oxygen that is supplied at high pressure. The mechanism relies on the principle that by restricting the flow of oxygen, the device can control the volume and pressure of the air delivered to the patient, allowing for effective artificial ventilation.

FROPVDs are beneficial in emergency medical situations as they do not require a good seal on the face, and trained personnel can operate them efficiently to provide quick assistance to patients who are unable to breathe adequately on their own. This can be particularly useful during advanced airway management when immediate oxygen delivery is critical.

In contrast, an Automatic Transport Ventilator (ATV) and Continuous Positive Airway Pressure (CPAP) devices do not utilize high-pressure oxygen to deliver ventilation in the same manner as a FROPVD. An ATV provides controlled mechanical ventilation but is not solely reliant on oxygen under pressure for function. The Bag-Valve Mask (BVM), while also used to deliver artificial ventilations, operates on manual methods and does not utilize pressurized oxygen in its mechanism. Thus, the FROPVD stands out as the correct device for this particular method of delivering
