Myasthenia gravis can be treated with a non-invasive ventilator, and it is generally manageable with medication. Early stages of myasthenia gravis may present with symptoms such as ptosis, poor breathability, respiratory difficulty, worsening symptoms after activity, and increased severity in the evening. Respiratory weakness might require treatment with a non-invasive ventilator. If respiratory weakness does not improve with medication and leads to respiratory failure, it is advisable to use a non-invasive ventilator to improve the patient's symptoms and alleviate difficulties. Respiratory muscle weakness can be life-threatening and requires active treatment.
