What should you do if you are alone and need to call for emergency help?

Using a cell phone while staying with the victim is the best course of action in this scenario. When you are alone and need to call for emergency help, maintaining your presence with the victim is crucial. This ensures that you can monitor their condition and provide assistance as needed while waiting for professional help to arrive.

When you call for emergency assistance with a cell phone from the location of the victim, you can accurately describe the situation to the operator and provide details about your location. This method allows for a quicker response since help can be dispatched while you continue to assist the victim.

Starting CPR immediately might seem like an appropriate action if the victim is unresponsive, but if calling for help can be done simultaneously using a cell phone, it's beneficial to do so. Leaving the victim to call 911 takes away critical care from them when they may need immediate assistance. Yelling for help could eventually attract attention, but it is unreliable and does not ensure immediate care for the victim. Thus, the choice of using a cell phone to call for help while staying with the victim effectively balances the need for emergency assistance with the requirement to tend to the person in need.
