This is one of the most important question that families tend to ask. Some patients can eventually breathe on their own. Some patients need to stay attached to machines forever. Unfortunately, it can be very hard to predict if your loved one will come off the breathing machine. However, older patients, patients with chronic health issues, and patients with severe brain injuries are less likely to be able to breathe on their own. Also, the longer someone needs a breathing machine, the less likely it is that the patient will ever come off.
