Advances in perinatal and pediatric intensive care and recent advances in mechanical ventilation during the last two decades have resulted in an exponential increase in the number of children undergoing home mechanical ventilation (HMV) treatment. Although its efficacy in chronic respiratory failure is well established, HMV in children is more complex than that in adults, and there are more considerations. This review outlines clinical considerations for HMV in children. The goal of HMV in children is not only to correct alveolar hypoventilation but also to maximize development as much as possible. The modes of ventilation and ventilator settings, including ventilation masks, tubing, circuits, humidification, and ventilator parameters, should be tailored to the patient's individual characteristics. To ensure effective HMV, education for the parent and caregiver is important. HMV continues to change the scope of treatment for chronic respiratory failure in children in that it decreases respiratory morbidity and prolongs life spans. Further studies on this topic with larger scale and systemic approach are required to ensure the better outcomes in this population.

Chronic eosinophilic pneumonia is an idiopathic condition characterized by chronic infiltration of the lung with eosinophils, weight loss, dyspnea, and pulmonary infiltration. Recently, we have experienced one case of chronic eosinophilic pneumonia presenting as the acute respiratory failure. A 34-year-old man was admitted to the hospital with one month's history of coughing, dyspnea, mucoid sputum, weight loss and one day's history of subcutaneous emphysema. The radiographic lung lesion and dyspnea rapidly progressed to a critical condition of acute respiratory failure. The combination of blood eosinophilia, lung infiltration on the chest x-ray, sign of acute rapiratory failure, rapid response to steroid therapy, and the finding of the transbronchial lung biopsy permit the diagnosis of chronic eosinophilic pneumonia.

Acute exacerbation(s) of chronic obstructive pulmonary disease (AECOPD) tend to be critical and debilitating events leading to poorer outcomes in relation to chronic obstructive pulmonary disease (COPD) treatment modalities, and contribute to a higher and earlier mortality rate in COPD patients. Besides pro-active preventative measures intended to obviate acquisition of AECOPD, early recovery from severe AECOPD is an important issue in determining the long-term prognosis of patients diagnosed with COPD. Updated GOLD guidelines and recently published American Thoracic Society/European Respiratory Society clinical recommendations emphasize the importance of use of pharmacologic treatment including bronchodilators, systemic steroids and/or antibiotics. As a non-pharmacologic strategy to combat the effects of AECOPD, noninvasive ventilation (NIV) is recommended as the treatment of choice as this therapy is thought to be most effective in reducing intubation risk in patients diagnosed with AECOPD with acute respiratory failure. Recently, a few adjunctive modalities, including NIV with helmet and helium-oxygen mixture, have been tried in cases of AECOPD with respiratory failure. As yet, insufficient documentation exists to permit recommendation of this therapy without qualification. Although there are too few findings, as yet, to allow for regular andr routine application of those modalities in AECOPD, there is anecdotal evidence to indicate both mechanical and physiological benefits connected with this therapy. High-flow nasal cannula oxygen therapy is another supportive strategy which serves to improve the symptoms of hypoxic respiratory failure. The therapy also produced improvement in ventilatory variables, and it may be successfully applied in cases of hypercapnic respiratory failure. Extracorporeal carbon dioxide removal has been successfully attempted in cases of adult respiratory distress syndrome, with protective hypercapnic ventilatory strategy. Nowadays, it is reported that it was also effective in reducing intubation in AECOPD with hypercapnic respiratory failure. Despite the apparent need for more supporting evidence, efforts to improve efficacy of NIV have continued unabated. It is anticipated that these efforts will, over time, serve toprogressively decrease the risk of intubation and invasive mechanical ventilation in cases of AECOPD with acute respiratory failure.

Toluene is an aromatic hydrocarbon found in glues, cements, and solvents. It is known to be toxic to the nervous system, hematopoietic system, and causes acid-base and electrolyte disorders. Acute respiratory failure with hypokalemia and rhabdomyolysis with acute renal failure should be considered as potential events in protracted glue sniffing. We reported the case of 26-year-old woman was admitted to the emergency department with the development of respiratory failure and altered mentality due to hypokalemia after chronic glue sniffing. She was weaned from the ventilator 3 days later after potassium and sodium bicarbonate replacement and was discharged without respiratory symptoms and other complications.

On 7 December 2007, the Hebei Spirit ran aground near Taean and released approximately 10,900 tons of oil into the sea. Crude oil on the coastal areas and fumes in the air increased the number of health problems among the local population. We report a case of respiratory failure after the oil spill clean-up work. A 66-year-old female was admitted to hospital with cough, sputum, and dyspnea of 1-month duration after the oil spill clean-up. She was diagnosed with community-acquired pneumonia and treated with empirical antibiotics. However, she had progressive respiratory failure without identification of the pathogen. Respiratory failure due to chronic inhalation of hydrocarbons from the crude oil spill clean-up was suspected. After mechanical ventilation care, she recovered from respiratory failure and was discharged. We report a case of severe respiratory toxic effects after an oil spill clean-up. We concluded that long-term hydrocarbon inhalation during the oil spill clean-up may have induced respiratory failure in this case.

Particulate matter (PM) is suspended dust that has a diameter of <10 ㎛ and can be inhaled by humans and deposited in the lungs, particularly the alveoli. Recent studies have shown that PM has an adverse effect on respiratory diseases. The aim of this article is to review respiratory diseases associated with PM. According to existing studies, PM is associated with chronic obstructive pulmonary disease, bronchial asthma, and several other respiratory diseases and increases the mortality rates of these diseases. Moreover, increased exposure in the high concentration of atmospheric PM is associated with the development of lung cancer. The most simple and common way to protect an individual from airborne PM is to wear a face mask that filters out PM. In areas of high concentration PM, it is recommended to wear a face mask to minimize the exposure to PM. However, the use of N95 or KF94 masks can interfere with respiration in patients with chronic respiratory diseases who exhibit low pulmonary function, leading to an increased risk of respiratory failure. Conclusionally, reduction of the total amount of PM is considered to be important factor and strengthening the national warning notification system to vulnerable patients and proper early management of exacerbated patients will be needed in the future.

The classical manifestation of asphyxiating thoracic dystrophy comprise narrow chest, short limbs, and pelvic changes. The degree of respiratory distress varied from negligible to lethal. The development of progressive renal failure may indicate that the condition is asphyxiating thoracic dystrophy. We have experienced a case of asphyxiating thoracic dystrophy who died from chronic renal failure in a 5-month old infant. Abriefreviewofassociatedliteratureisalsopresented.

연구배경: 심인성 폐부종은 임상실험이나 동물실험에서 비특이적 기도과민 반응을 증가시킨다는 많은 보고가 있다. 또한 만성 신부전 환자는 혈관밖 폐수분 증가에 의하여 무증상에서 명확한 폐부종까지 다양한 임상 양상을 보이고 있다. 여러 보고에 의하면 만성 산부전 환자에서 혈관 밖 폐수분 증가로 폐활량이 감소하며 혈액투석 후는 폐 간질성 부종의 감소 혹은 소설로 폐활량이 호전 된다고 한다. 그런데, 이 폐 간질성 부종이 비특이적 기관지 과민 반응을 야기하는 한 기전으로 생각하고 있다. 그래서 연구자들은 만성신부전 환자에서 폐간질성 부종에 의하여 기관지 반응이 증가되는지 여부를 알기 위하여 본 실험을 시행하였다. 방법: 다른 동반질환이 없는, 1주에 3번씩 혈액투석을 하고 있는 18명의 만성신부전 환자를 대상으로 하였다. 이 환자들은 혈액투석전 폐기능 검사와 메타코린 기관지 유발검사를 하였고, 기관지 과민반응을 나타낸 환자는 혈액투석후 폐기능검사와 메타코린 기관지 유발 검사를 반복 시행하였다. 결과: 1) 18명중 12명에서 혈액투석전 메타코린 기관지 수축 유발검사에서 양성 반응을 하였고(66.7%), 이 기관지 과민반응은 혈액투석후 감소되었다. 2) 폐기능은 혈액투석후 호전되었고, 혈액투석 전후 $FEV_1$ 변화와 체중 변화는 유의한 상관 관계가 있었다(r=-0.62, p<0.01). 3) $PD_{20}$와 $FEF_{25}$ 사이에도 유의한 상관관계가 있었다(r=0.59, p<0.05). 결론: 만성 신부전 환자에서 관찰된 폐기능 저하와, 기관지 과민성 반응은 폐 간질성이 부종에 의할 것으로 사료된다.
