Mechanically ventilated patients interact with ventilator functions at different levels such as triggering of the ventilator, pressurization and cycling from inspiration to expiration. Patient ventilator asynchrony in any one of these phase results in fighting with ventilator, increase in work of breathing and respiratory muscle fatigue. Patient ventilator dyssynchrony occurs when gas delivery from the ventilator does not match with the neural output of the respiratory center. ⋯ Patient-ventilator interaction during noninvasive mechanical ventilation may be affected by the type of masks used, ventilator types, ventilation modes and parameters, humidification and sedation. Among the different patient groups it is important to know causes and solutions of patient-ventilator asynchrony problems. By this way patient will adapt ventilator and then dyspnea, ineffective respiratory effort and work of breathing may decrease subsequently.

In Turkey, there is inadequate data about the direct or indirect cost of community acquired pneumonia (CAP). This study aims to identify the clinical, laboratory, and radiological properties, direct hospital costs of CAP, and the factors that affect these costs. Grouping of the subjects and cost analysis were evaluated in accordance with Pneumonia Severity Index (PSI) and 'Turkish Thoracic Society (TTS) CAP Guideline'. 114 cases with an average age of 70.9 were analyzed retrospectively. ⋯ Existence of a comorbid disease was detected to have increased the total cost (p= 0.003). Total costs according to PSI scoring were 1274.60 Euro in low-risk group, and 1929.49 Euro in high-risk group (p= 0.04). Hospital mortality due to CAP was 2.6%.

Case Reports[Entrapment of a Swan-Ganz catheter within the right pulmonary artery ligature during right pneumonectomy].
Entrapment of a pulmonary artery catheter in the pulmonary artery is a rare and severe complication that may lead to fatal complications such as pulmonary artery injury. We describe entrapment of a Swan-Ganz catheter within the right pulmonary artery ligature in a patient undergoing right pneumonectomy. This situation resulted with removal of catheter safely without any complication. We concluded that with early recognition of the complication during thoracotomy, is golden standard in preventing pulmonary artery catheter entrapment and surgeons should be aware of the risk of accidentally transfixing pulmonary artery catheter in every type of operation that takes place in thorax.

Review[Current strategies for the diagnosis and treatment of acute respiratory distress syndrome].
Acute respiratory distress syndrome is a frequently encountered condition in the intensive care units, with high mortality rates despite cumulating knowledge on its pathogenesis. It is important that cardiac pulmonary edema should be ruled out for diagnosis. ⋯ Low dose steroids, nitric oxide inhalation, surfactant, antioxidants, Beta(2) adrenergic agents, HMG-CoA reductase inhibitors are promising agents. Fluid restriction and immunonutrition should be considered when these patients are being cared for.

Randomized Controlled Trial[The clinical and microbiological comparison of the use of heated humidifiers and heat and moisture exchanger filters with Booster in mechanically ventilated patients].
Ventilator associated pneumonia (VAP) is the most frequent nosocomial infection in intensive care units that is associated with prolonged mechanical ventilation, hospitalization and increased health-care costs. Various humidifiers can be used for humidification during mechanical ventilation. Many studies were conducted to identify the effects of two different humidifiers, i.e. heated humidifiers and heat and moisture exchanger filters (HME), on VAP development; and HME filters were found to decrease the VAP frequency. ⋯ The rate of VAP and endotracheal tube occlusion was not significantly different between the groups. The mean secretion score was lower in group 1 (p= 0.041). In conclusion, although both humidifiers have similar microbiological effects, heated humidifiers could be preferred particularly for the patients with an underlying chronic lung disease due to its positive effects on PETCO(2) values and secretion scores.
