<s>[INST] my dad has copd. over the weekend he got too hot and passed out if you will. he got light headed and we sat him in a chair and his eyes rolled back, and he started shaking and sweating. he does not remember anything. he came to in about 5 to 7 seconds later, could this be some type of seizure? or is this common in patients with copd?? thank you in advance for your response.
