"The demands remain the same. The expectation when it comes to the Indian cricket team has always been the same," Dhoni said at the launch of the Celkon Mobile Cup here.
"If it's moving, it only moves in one direction - it goes up. It doesn't matter whether we have won the last series or lost or what has happened on the field," he explained.
India play West Indies in their first game at the Sabina Park here on Sunday.
Dhoni attributed the team's recent success to a friendly dressing room atmosphere where the players "enjoy each others success".
The Champions Trophy triumph in England means India, the numero uno side in the ICC rankings, now hold both the major ODI titles following their victory in the World Cup on home soil two years ago.
And Dhoni said he was lucky to have players at his disposal who are not afraid of pressure.
"I'm fortunate to have the players in the side to really soak up the pressure," he said.
"What we have done really well is we have enjoyed each others' success and that has really contributed to the side winning most of the games," the wicket-keeper batsman said.
"If I'm happier than the person who has actually scored a century or a fifty, you understand that's the kind of atmosphere that you want, because at the end of the day, what we play is a team sport," he added.
