<s>[INST] My husband was sitting in bed eating. He turns ovr vomits, then falls off bed unconscious. He didnt show any signs of choking, or gasping for air. It took me several minutes to make him come to. He said he was joking is this possible without showing the usuall choking signals Im really scared its something worse? [/INST] I'm a little surprised you didn't say that you called 911 if you are sure he became unconscious which is usually not hard to tell. It is certainly possible for someone to choke on something without making a noise, but usually a witness can describe other things happening such as a sudden flushing in the face and the person themselves usually becomes desperate and may even thrash about trying to dislodge whatever they are choking on. I think you need to get your husband evaluated as he may have had something else happen that caused that entire event. </s>
