The statement “Why don’t you use a ventilator for polio-induced respiratory muscle weakness iron lung” is incorrect. A ventilator can be used if the polio patient has symptoms such as dyspnea and apnea. Adverse effects such as flatulence, aspiration, and difficulty in expectoration may occur with the use of a ventilator. Patients with polio have a variety of clinical presentations, with symptoms varying greatly between clinical subtypes. In severe cases, asymmetric flaccid paralysis and even respiratory muscle paralysis can occur, which can be life-threatening. Ventilators may be used when patients have symptoms such as dyspnea and apnea. Adverse effects may occur with the use of ventilators, such as skin lesions, flatulence, aspiration, difficulty in expectoration, dryness of the mouth and throat, and pneumonia. Patients with polio should choose whether or not to undergo ventilator therapy under the guidance of a doctor.
