We do have LP-15, but the auto BP is optional (not standard). We also do not use the built in SAO2 on the LP-15. We do manual BPs, use a handheld SAO2, and use the EKG for EKGs. I know it sounds pretty silly, but the intent is two-fold.
First, the more gadgets on a machine, the higher the chances it breaks. The built in BP, SAO2 are nice features, but it is still fluff.
Second, by making crews take BPs it encourages more "hands on" the patients. So many crews today put on the probes, electrodes, and monitors and don't actually put hands on the patients.
