I would suggest on an emergency deal like that that the Reciever/Dryer be replaced... with the right amount of correct oil placed in it ....of course...because the theory is that any leak means air/water vapor cantamination in the system... replacing it this emergency fix may help because you are not flushing.. and the moisture which has gotten into the oil...and been caught by the dessicant in the R/D is not subject to evacuation (vacuuming of the moisture out)....
At some time when you have more time... to safeguard the compressor..... since when you have a leak typically you lose oil with it..... and therefor do not know how much oil is in your system... that at some point you have the system flushed, and refilled measureing the amount of oil put back in...
too much oil is bad and too little is bad....
