There is a need for portable and less expensive devices for patients with chronic respiratory insufficiency. The case of a 44-year-old Hispanic woman is illustrative. The patient had severe restrictive lung disease secondary to right phrenic nerve crush/pneumoperitoneum and left pneumonectomy/decortication for bilateral lower lobe tuberculosis. In 1969, 12 years after her last operation, she developed dyspnea, coryza, and somnolence. She was hospitalized with a PaO2 of 30mmHg; PaCO2 of 77mmHg and a pH of 7.28. Pulmonary function tests showed alveolar hypoventilation and her resting ventilation was between 2.26 to 3.74L/min. Her vital capacity was 1130cc (37% of predicted value) and maximum breathing capacity was 36L/min (44% of predicted value). From 1969, she used a poncho (wraparound) ventilator for her long-term respiratory care and modified the poncho suit to meet her personal needs. In 1971, she discovered that a mouth intermittent positive pressure ventilation (MIPPV) method, often used by patients with neuromuscular disorders, was easier to apply. Since then, she has continued to use a Bantam Respirator with MIPPV and a lipguard/mouthpiece during the night, and the respirator with a mouthpiece for a few hours during the days. However, when she has an upper respiratory infection or feels tired, she finds that she needs the greater rest and comfort that the poncho provides. With the assistance of these two respiratory devices, she has been able to complete her education, marry, and lead a fulfilling life in the community. This patient is considered the first person with severe lung pathology to utilize MIPPV for sleep.
