It is called a BVM or bag valve mask that is not recommended for single person use.
The bag-mask device is not recommended for a single rescuer to provide breaths during CPR.
I assume this is a test question. Shame, shame. :) Unless the rescuer is trained with proper equipment, simply provide compressions. Do not stop for breaths as it is more effective without them.
30 compressions to 2 vents, for a single person, lay rescuer.
A 100 ton metal press.
By holding and tipping the head back.

Pulmonary ventilation is the volume air that is breathed in or out in a single minute. It is the sum of the tidal volume (volume of air per breath) and the ventilation rate (the number of breaths per minute). For an individual's pulmonary ventilation to increase, there must be an increase in at least one of these two values. The individual can begin breathing deeper at the same rate (increasing tidal volume) or the individual can begin breathing faster at the same volume (increase ventilation rate) or both.
at a tim one device
i think yes it is a single user device
Phase to phase, two wire is classed as single phase. If the voltage from the phase to phase match the device's operating voltage, then connecting the device will allow it to operate.
No.
