Ron was a soldier; he had been to many battlefields in his lifetime, and aside from having a strong body, he also had a massive amount of experience.
He knew that when transporting injured comrades, it was very careless to ignore their physical condition.
Ron immediately knew that Paul's body was weakening and he was losing his consciousness.
And if he loses consciousness, perhaps his body will make him go into a coma, and his mind might not wake up again due to the trauma he has suffered.
To prevent Paul from suffering that fate, he was continuously chattering with Paul like a chatterbox.
Even if it was just random nonsense and small talk, Ron was doing his best to keep Paul sane and conscious.
Making Paul remember his loved ones was also a method to give him a reason to keep living and pushing forward.
As they say, a warrior doesn't lose until he himself accepts the loss in his mind and body.
