Answer :
The most accurate statement about bag-valve-mask resuscitators (BVMs) among the given options (c) Ventilations are more effective when two rescuers operate the BVM.
When a single rescuer is performing cardiopulmonary resuscitation (CPR) using a BVM, it allows for better coordination with chest compressions. This is because the rescuer can provide ventilations by squeezing the bag while also being able to time the compressions effectively. The ability to coordinate both actions is crucial for maintaining adequate oxygenation and circulation during CPR. Having two rescuers operating the BVM allows for better coordination and efficiency in providing ventilations to the victim. One rescuer can focus on maintaining a proper mask seal and delivering the ventilations, while the other rescuer can assist with proper positioning of the victim's airway and monitoring their response. This two-rescuer approach ensures adequate ventilation and reduces the risk of interruptions or inadequate breaths. In contrast, using a BVM as a single rescuer may pose challenges in coordinating ventilations with chest compressions during cardiopulmonary resuscitation (CPR).

option c. Ventilations are more effective when two rescuers operate a BVM. This ensures a proper seal and effective delivery of breaths. Single-rescuer operation can be challenging to coordinate with chest compressions effectively.
The most accurate statement about bag-valve-mask resuscitators (BVMs) is that ventilations are more effective when two rescuers operate the BVM. A BVM involves a manual resuscitator used to provide positive pressure ventilation to individuals who are not breathing or not breathing adequately. Using a BVM effectively often requires two rescuers: one to maintain a tight seal on the mask and another to squeeze the bag, ensuring that ventilations are delivered properly.
- BVMs are readily available at all emergency scenes. This is not true, as the availability of BVMs can vary depending on the location and resources of the emergency responders.
- Monitoring the victim for full exhalation is not required. This statement is incorrect; it's very important to monitor for full exhalation to avoid potential complications such as barotrauma.
- Ventilations are more effective when two rescuers operate the BVM. This is the correct answer because two rescuers can ensure a better seal and more effective ventilations.
- When used by a single rescuer, BVMs allow easy coordination with chest compressions. This is incorrect. It can be quite difficult for a single rescuer to coordinate BVM use with chest compressions efficiently.
