Harry, a taxi cab driver, is found parked in his taxi and in great pain. He has a puncture wound in his right thorax (where he had been stabbed by an assailant), and the paramedics correctly determine that his lung is collapsed. When he is taken to the hospital and blood gas measurements are taken, he is found to have a high arterial PCO2 and a pH of 7.15. He is treated surgically, and during his recovery smokes numerous cigarettes despite his physician's warning.When blood gas measurements are again performed, his arterial PCO2 and pH are found to be normal, but he shows a car-boxyhemoglobin saturation of 18%. Pulmonary function tests are ordered, and they reveal that he has a vital capacity slightly below normal and an FEV| that is significantly lower than normal.
What condition did Harry have when he was rushed to the hospital? What was the cause of the initial blood gas results, and of his later carboxyhemoglobin levels? Also, what do the pulmonary function tests suggest about Harrry's health?

Among the evils which a vitiated appetite has fastened upon mankind, those that arise from the use of Tobacco hold a prominent place, and call loudly for reform. We pity the poor Chinese, who stupifies body and mind with opium, and the wretched Hindoo, who is under a similar slavery to his favorite plant, the Betel but we present the humiliating spectacle of an enlightened and christian nation, wasting annually more than twenty-five millions of dollars, and destroying the health and the lives of thousands, by a practice not at all less degrading than that of the Chinese or Hindoo.
