Authors' conclusion

DA-CPR in the VG was associated with associated with higher odd of favorable neurological outcomes and survival in patients with OHCA, while instruction and CPR initiation times were modestly longer. Optimizing protocols to reduce video transition workflows and incorporating dispatch-center and technical variables should be priorities for future prospective studies.
