They're good.I want to suggest that a person's lungs are suffering because of pollution or other factors.
Are these good?
1. The air was polluted more days than it was clean. The city's inhabitants escaped to the countryside to soothe their poisoned lungs.
That tells us everyone deserted the city. If only some of them left town, say something like
- City inhabitants
- Many of the city's inhabitants
- A lot of city inhabitants
2. The guerillas had used tear gas. John and Nicole escaped back to their hotel room, coughing viciously and drinking water to calm their poisoned lungs.
