I'm really worried about my dad. He's a smoker and he's got issues with sugar and BP. He came down with a bad fever and weakness over the last five days, but the tests didnt show dengue or typhoid. After admitting him to the hospital, he suddenly started having trouble breathing, was sweating a lot, and his oxygen levels dropped. The doctor had to move him to the ICU and put him on a ventilator. They said he's got pneumonia and his left lung is affected. They took a sample for a culture report, but thats going to take 35 days. He's been on the ventilator for the last 20 hours, but theres no improvement. His BP also dropped, but they managed to control it with a high dose of meds. We're all quite anxious and I'm just trying to understand what the recovery process might look like from here. Could you shed some light on what we should expect or do next?
