Controlled Clinical Trial
Optoelectronic vital capacity measurement for restrictive diseases.
To determine whether optoelectronic plethysmography accurately evaluated vital capacity (VC) in patients with respiratory muscle dysfunction of variable severity, including those with paradoxical abdominal movements. ⋯ Optoelectronic plethysmography is accurate and suitable for VC measurement in patients with various degrees of respiratory failure, including those with paradoxical abdominal movements. This noninvasive method may be an attractive alternative for accurately measuring VC in the event of air leakage (through the mouth or tracheostomy) or when patients are unable to breathe with the dead space added by the spirometer.

The aging Taiwan population is expected to require vast medical resources, including prolonged mechanical ventilation (PMV). This study determined the trends in hospital resource utilization and associated factors in PMV patients in Taiwan. ⋯ These population-based data demonstrated a decrease in the prevalence of PMV, especially for older patients, and that stay decreased; however, hospital treatment costs increased. Moreover, healthcare providers and patients should recognize that attributes of both the patient and the hospital may affect hospital resource utilization. Additionally, these analytical results should be applicable to similar populations in other countries.

A combination of helium and oxygen (heliox) can facilitate gas exchange and limit peak inspiratory pressures through reduced resistance to gas flow and decreased turbulent flow. The combination of these gases has been used for a variety of upper and lower airway conditions, including patients who were spontaneously breathing, receiving noninvasive ventilation, as well as during mechanical ventilation. ⋯ We report the use of such a combination of gases in 2 patients with bronchiolitis obliterans syndrome following lung transplantation as a supportive measure to facilitate ventilation during the initial treatment course for acute respiratory failure in the ICU. A heliox mixture was administered with noninvasive ventilation and with mechanical ventilation through the ventilator in a heart-lung transplant recipient and a lung transplant recipient, respectively.
