Medical masks, such as oxygen masks, are generally used as a way to treat medical conditions or prevent the spreading of diseases. The masks worn by surgeons protect the patient just as much as they protect the doctor. While an oxygen mask does not provide protection per se, it does allow a patient with a lung problem, such as [[emphysema]] to lead a normal life. | Medical masks, such as oxygen masks, are generally used as a way to treat medical conditions or prevent the spreading of diseases.
