Pulmonary Physicians manage basic Pulmonary disease, such as COPD, asthma (which can go to Allergy as well), Interstitial Lung Disease (Sarcoid, GoodPastures, etc.), Pleural Effusions in both the in-patient and out-patient settings. They can use their critical care background to manage Ventilators in the ICU. These days, a lot of Pulm/CC doctors have gotten into Sleep Medicine, which is lucrative. Basically, you run a sleep study on someone and prescribe BiPap or CPAP to help them sleep at night and follow up with them. The average hours are probably 50-60 or so per week. These averages are not that helpful, as the amount that you work depends on the amount of work you have to complete. Since you don't work for free, the more you work, the more money you make! Most days are probably pretty routine. However, in a Pulm/CC group, the calls must be pretty tough, since you have some critically ill patients. I have been told that the typical starting salary for a Pulm/CC doctor without Sleep training is around $220,000 per year. I think Sleep can add to that quite nicely, probably $5-15 K per month, depending on volume and whether or not the group already has a sleep specialist.
