2. Assisted ventilation: For some patients who have difficulty breathing or need assisted breathing, the ventilator mask can provide additional oxygen or airflow support to help them maintain normal breathing.
3. Long-term care: For patients who need to rely on ventilators for a long time, the ventilator mask is an indispensable part of their daily life. It can provide stable oxygen or airflow to maintain the patient's normal breathing.
