On older model Gulfstreams I had worked on (even 1978 G2) they had considerable breathing O2 capacity to match their operating altitude and over water legs, guessing a little to reaching land meant not descending immediately below 10,000ft mostly because of the single pack !
The one time depressurization occurred at altitude (+38,000ft) the flight deck filled with mist, the pilots scrambled to get their mask on, as you don't have long to live let alone work, one knocking his reading glasses off then a decent and hasty search for the relevant Jeppesen.
Yes, C 550 has a cabin altitude warning.
Found in C550 MEL
