Fabrice Muamba is currently recovering at the London Chest Hospital, where his condition is now described as "comfortable" in intensive care.
The news is far more positive after the Bolton midfielder's heart stopped for two hour following his collapse during the first half of the FA Cup quarter-final at White Hart Lane on Saturday evening.
Muamba joined Arsenal as a schoolboy after moving to England aged 11 from the Democratic Republic of Congo, and went on to play in the first team before joining Birmingham in May 2007 following a loan spell.
Premier League chairman Richard Scudamore has promised a review into medical procedures at football grounds, but Manchester City boss Roberto Mancini does not believe what is currently in place is good enough, demanding twice-yearly medical screenings.
Wenger believes clubs do what they can to make sure any underlying health problems are brought to light.
"He had regular screens everywhere; here, at Birmingham and at Bolton as well," Wenger told Arsenal Player.
"I am not a specialist enough in medicine to say 'is the screening enough for the kind of problem that he had?'
"It raises a few questions, but you need to be better informed on what happened to him to see if the players need deeper analysis of heart problems.
"You can always learn something out of these situations and that is maybe what we can learn out of it."
Wenger continued: "It is too early to ask whether it is a lack of control, does football need to go in deeper with research or deeper in control with heart problems to stop these kind of situations.
"If it is preventable - at the moment nobody has given us any answer, but that is what you are waiting for. Our medical team tell me that there is constant ongoing research in this area and that it must continue."
Some of the current Arsenal squad remain good friends with Muamba.
Wenger added: "He is a loved guy. Because we have a young team, many of them grew up with Fabrice and there was a strong link when you fight together in the youth teams because it creates a special bond.
"The players were quite low yesterday and two days ago, but today it is a bit better because we have good news about him."
