Dr Pichit Siriwarn, rescue chief of the Red Cross Society said that his office now prepared personnel, medical supplies, ambulances as well as emergency mobile communications unit and 25 satellite phones in case of emergency.
The preparation is aimed at minimize any loss if there is more clashes.
"Princess Maha Chakri Sirindhorn is worried about the situation. The princess assigned medical teams to be ready if some clashes happens," Dr Pichit said.
Medical units will be set up at Chamai Maruchet Bridge and the teams will cooperate with Narantorn Rescue Centre to work out emergency plans to come to reach people as soon as possible in case of emergency.
Clashes between police and anti-government protesters on Friday left many injured, particularly when police fired tear gas to the protesters.
