“…Although all patients completed the study, six were not compliant with the ventilatory treatment. This subset of patients did not show improvement in MIP and Pa,CO 2 [26]. SAURET et al [86] studied 17 patients with severe COPD (forced expiratory volume in one second (FEV1) 0.60±0.15 L) in acute hypercapnic respiratory failure due to intercurrent bronchial infection.…”

“…MONTSERRAT et al [26] evaluated the acute effects of NPV in 20 consecutive patients with COPD in ARF due to bronchial infection (table 2). Arterial blood gas tensions and maximal inspiratory pressure (MIP) were measured before and after 6 h of NPV or conventional medical treatment given in random order on two consecutive day.…”

“…In these studies, an iron lung [25] and a ponchowrap [26] were used, respectively, to administer NPV. In these reports, NPV, carried out continuously for 6 h [26], or intermittently for 7 days (8 h·day -1 ) [25], was found to be effective in improving respiratory muscle strength and in decreasing arterial carbon dioxide tension (Pa,CO 2 ). The effects of NPV on electromyographic activity (EMG) of respiratory muscles in patients with ARF have not been investigated.…”

Negative pressure ventilation in the treatment of acute respiratory failure: an old noninvasive technique reconsidered. A. Corrado, M. Gorini, G. Villella, E. De Paola. ©ERS Journals Ltd 1996. ABSTRACT: Noninvasive mechanical ventilatory techniques include the use of negative and positive pressure ventilators. Negative pressure ventilators, such as the "iron lung", support ventilation by exposing the surface of the chest wall to subatmospheric pressure during inspiration; whereas, expiration occurs when the pressure around the chest wall increases and becomes atmospheric or greater than atmospheric.In this review, after a description of the more advanced models of tank ventilators and the physiological effects of negative pressure ventilation (NPV), we summarize the recent application of this old technique in the treatment of acute respiratory failure (ARF). Several uncontrolled studies suggest that NPV may have a potential therapeutic role in the treatment of acute on chronic respiratory failure in patients with chronic obstructive pulmonary disease and restrictive thoracic disorders, reducing the need for endotracheal intubation. In the paediatric field, after substantial technical improvement, NPV has been successfully reintroduced for the treatment of ARF due to neonatal distress syndrome and bronchopulmonary dysplasia, and for the weaning from positive pressure ventilation in intubated patients.The positive results of these reports need to be formally confirmed by further prospective and controlled studies before recommending the generalized use of negative pressure ventilation in acute respiratory failure as a standard of care.

Chronic obstructive pulmonary disease (COPO) is the only leading cause of death with a rising prevalence It is the fourth leading cause of death in the United States and accounts for approximately 500,000 hospitalizations and 110,000 deaths for exacerbations each year. Patients who are admitted to the intensive care unite (ICU) for COPO exacerbations have an in-hospital mortality of 24%.1-4 It has been estimated that by the year 2020, COPO will be fifth among the conditions that will be the most burden to society.5Morbidity and mortality due to COPO vary dramatically between industrialized countries. These variations have been attributed to different exposures to risk factors such as tobacco, atopy, occupational hazards, genetic factors, and air pollution. Outside the United States, COPO has had a similar impact on health and mortality throughout the developed and underdeveloped world, and many of the important issues surrounding COPO in the United States applyelsewhere. 6 DefinitionsThe term COPD, as recommended by the American Thoracic Society, must be applied to patients who have chronic bronchitis and/or emphysema with significant airflow limitation that does not change significantly over a period of several months of observation, thus distinguishing these patients from those with asthma. 5New definitions of acute COPO exacerbation (AECOPO) have been suggested, but the one widely accepted is generally considered as the presence of one or more of the following findings: increase in sputum purulence, increase in sputum volume, and worsening of dyspnea. Patients with COPO present acute decompensation one to three times a year, and 3% to 10% require hospitalization.1.2 Assessment of the magnitude of these three symptoms can determine the severity of an exacerbation. When all three symptoms are present, it is a type I exacerbation. If any two of the three symptoms are present, it is 101 G. Ortiz-Ruiz et al. (eds.), Sepsis
