How to use a for loop for repetitive timed actions

I am trying to figure out how to use a for loop for some repetitive timed actions. A snippet of the code I am using right now is shown below, although only showing 2 repeats. I haven't been able to come up with something that seems like it would work.

CASE ten_sec_cnt IS

WHEN "000" =>

IF ((rollovr_cnt = X"0") and (duration = X"00")) THEN

next_red <= '0'; -- turn red LED on

next_av_done <= avdone;

next_state <= state;

ELSIF ((rollovr_cnt = X"1") and (duration = X"F2")) THEN -- time = 5 sec

next_red <= '1'; -- turn red LED off

next_av_done <= avdone;

next_state <= state;

ELSIF ((rollovr_cnt = X"2") and (duration = X"B9")) THEN -- time = 7 sec, double-flash, start of 10 seconds

next_red <= '0'; -- turn red LED on

next_av_done <= avdone;

next_state <= state;

ELSIF ((rollovr_cnt = X"2") and (duration = X"D2")) THEN -- time = 7250 ms

next_red <= '1'; -- turn red LED off

next_av_done <= avdone;

next_state <= state;

ELSIF ((rollovr_cnt = X"3") and (duration = X"04")) THEN -- time = 7750 ms

next_red <= '0'; -- turn red LED on

next_av_done <= avdone;

ELSIF ((rollovr_cnt = X"3") and (duration = X"1C")) THEN -- time = 8 sec

next_red <= '1'; -- turn red LED off

next_av_done <= avdone;

next_state <= state;

ELSIF ((rollovr_cnt = X"3") and (duration = X"80")) THEN -- time = 9 sec

next_red <= '0'; -- turn red LED on

WHEN OTHERS => null;

END CASE;
