When my father installed a pacemaker in the hospital, the doctor punctured his lung, causing pneumothorax and pleural effusion. Can I ask the hospital for medical compensation?

My personal suggestion is to discuss with the hospital first. If the two sides can solve it through consultation, there is no need to take legal channels. If negotiation is not appropriate, you can try to find a lawyer. Now, the proof should be reversed. If we really want to take legal channels, we must produce evidence about the infringement and the consequences of the damage. In other words, it is necessary to provide certain evidence to the court to prove that he has indeed received treatment or surgery in that hospital, and the hospital has caused damage to his rights and interests. Lawyers should be clear about the specific process or something. But in any case, we must protect the medical records.
