My friend is not feeling well. I have called an ambulance, and would like to know how best to treat them until professional help arrives. They are feeling dizzy and confused, and cannot form a coherent sentence. They appear to be running a fever and are struggling to walk.
If your friend is experiencing these symptoms, it's important to act quickly and take steps to keep them safe and comfortable until medical help arrives. Here are some things you can do:

1. Stay with your friend and keep them calm. Talk to them in a soothing voice and let them know that help is on the way.
2. Help your friend lie down in a comfortable position, preferably on their side if they are feeling nauseous or vomiting.
3. If your friend has a fever, try to cool them down by removing any excess clothing and using a cool, damp cloth on their forehead and neck.
4. Offer your friend water to drink if they are able to swallow. Make sure it is not too hot or too cold, as extreme temperatures may worsen their condition.
5. If your friend has any medication that they take regularly, make sure to have it on hand to show to the medical professionals when they arrive.

Remember, every situation is unique and these tips are not a substitute for professional medical advice. Always call for emergency medical assistance if you believe your friend is in serious danger or requires immediate medical attention.
Going by the FAST method, they're not Stable since they're dizzy, and they can't form sentences so they can't Talk.

Why didn't you tell me about the basic FAST method, or FASTER, and that these are symptoms of a stroke? FASTER recommends trying to remember when it first began. Should I do anything else?
I apologize for not mentioning the FAST method earlier. You are correct that your friend's symptoms could be signs of a stroke, and it's important to act quickly.

The FASTER method is an extension of the FAST method and stands for:

*    Face drooping
*    Arm weakness
*    Speech difficulties
*    Time to call emergency services
*    Eyesight changes
*    React immediately

As you have identified, your friend is experiencing speech difficulties and dizziness, which are both signs of a stroke. In addition to the steps I mentioned earlier, it's important to note the time when you first noticed these symptoms, as this information can be important for medical professionals.

If your friend is conscious and able to speak, you can ask them if they are experiencing any pain or discomfort, as this information can also be helpful for the medical team.

It's important to stay calm and reassure your friend while you wait for the ambulance to arrive. If your friend's condition worsens, or they become unresponsive, call emergency services again and follow their instructions.
