CO2 hose leaked

A co2 line to my keg came loose and leaked out the entire CO2 cylinder completely. The hose came loose at the keg and thus the keg was open to the atmosphere and the head pressure in the keg was 0 psig. This all happened in the refer and in a 24 hour period. I must have bumped it loose when I checked on it last night. The keg had been carbing for a week and was nearly 100% carbonated. It's too late to get a cylinder this evening , so it will have to wait until tomorrow evening to get co2 back on the system. I am very new to kegging and home brewing, is there anything I should do until I get co2. I removed the QD's and left the keg in the refer.
Will recarbonating the flat beer affect the beer?

it should be fine until you get the C02 refilled just leave the keg pressurized in the fridge.

Invest in some hose clamps!
