Continuity mistake: The mistake begins at 00:13:11 while Andrews is talking with the patient's partner. Between the cuts, you can see, that the "necklaces" with the pictures of them disappear and appear. This goes on for like 3 to 5 cuts and every time the necklace is there and in the next shot not. (00:13:11 - 00:13:57)
Continuity mistake: When Dr. Andrews tells Mrs. Cross via video chat that her husband has blood in his NG tube, the clock in the top left corner of Mrs. Cross' phone says 5:09. Two shots later, it has suddenly changed to 5:01. A few moments later it changes to 5:10, then back to 5:01 and then for some reason to 4:53 at the end of the scene.
