Hi, I’m a paramedic x14 yrs. Didn’t watch the video, but I don’t think this is likely to be the case. In almost every case I’ve seen pink-tinged foamy sputum from CHF, the patient is in critical condition, and is in absolutely no state to be delivering a deranged rant. Even in the cases where they work on it with hacking and coughing for a bit, they’re still pretty much out of gas and not going to be carrying on like dumbass here. At least, that’s my experience.
