The Face

Background: The aim of this study was to evaluate the effect of a newly designed foam cushion on the air leakage and pressure when applied to the face. Methods: A teaching manikin connected to a bilevel positive airway pressure ventilator attached to four different brands of oronasal masks (Amara, Mirage, Forma, and Wizard) was used. The foam cushions of 5-mm and 10-mm-thickness were attached to the masks, and each mask was tested without a cushion. Six pressure sensors were placed on the manikin’s face, and data were recorded. Inspiratory volume and air leak flow from the ventilator were observed. Results: Air leakage was influenced by both the mask brand and the presence of a cushion. The presence of a cushion did not affect the Wizard mask in terms of leakage (p = 0.317) or inspiratory volume (p = 0.726). The Wizard and Amara masks generated the lowest contact pressure on the frontal forehead (p < 0.001) compared to the other five points. Conclusions: Utilisation of a cushion reduces air leakage and maintains greater inspiratory volume regardless of its thickness. The contact pressure varies depending on the brand of the mask, which would require a difference in the thickness of the cushion for pressure reduction.

Background: Location of the affected bronchus of pleural air leaks is the most important step of trans-bronchoscopic bronchial occlusion for the treatment of intractable pneumothorax. The balloon occlusion test is the most commonly used technique, but has failed in some cases. The aim of the present study was: (1) to determine if endo-bronchial end-tidal CO2 (EtCO2) measurement can identify the affected bronchus that is the source of a persistent pleural air leak; and (2) to establish a methodology for endo-bronchial EtCO2 testing in locating affected bronchus in intractable pneumothorax. Methods: A total of 28 patients with intractable pneumothorax underwent bronchoscopy with (1) the balloon occlusion test for the identification of the affected bronchus; and (2) endo-bronchial EtCO2 measurement (EtCO2 test) at the orifices of the bronchus of the affected lung. The effectiveness of these two methods of affected bronchus identification were compared. The threshold EtCO2 (T-EtCO2) was determined. Results: The positive rates of locating the affected bronchus by the endo-bronchial EtCO2 test, balloon occlusion test, and combination of the two techniques were 60.7% (17/28), 64.3% (18/28) and 96.4% (27/28), respectively. The average differences in EtCO2 between the affected bronchus and the main carina, main bronchus, and non-affected bronchus were (in mmHg) 4.41 ± 1.99 (95% confidence interval: 3.5, 5.3), 4.73 ± 2.10 (3.80, 5.66 ) and 5.57 ± 2.53 (4.45, 6.69), respectively. Conclusions: (1) The endo-bronchial EtCO2 test is complementary to the balloon occlusion test of the leading bronchus. (2) A threshold (T-EtCO2) value of >5 mmHg is optimal for this technique.

Objectives - to analyze the causes of postoperative air leak and to propose a therapeutic and diagnostic algorithm for this complication. Material and methods. The study includes the analysis of the prolonged air leak causes after various lung resections, the classification of the causes according to their affiliation, the designed definitions of basic concepts. Results. The most common causes of prolonged air leakage are the incompetence of the lung resection line, the undetected (unresolved) cause of pneumothorax, the inadequate drainage system function. Various tactical approaches to this problem were described. Depending on the effectiveness of the auxiliary techniques, the indications for repeated operations were determined. Conclusion. Knowledge of the causes of postoperative prolonged pathological air leak is the basis for the optimal management of patients after lung resection.

Air Leak Test

Ford Otosan’s Yeniköy plant, which assembles the Transit Courier and Tourneo Courier, has developed a innovative air leakage test method. Air leakage is not a directly measurable metric by customer, but it can be observed in some different ways such as wind noise, road noise, water ingress, dust intrusion, door closing efforts, and better cooling/heating performance. In order to detect leak point by conventional method is dramatically time consuming, needed to remove trim parts and issues under 11/s could not be detectable. Innovative air leakage test method has been designed by using air heater unit, air leak test device and thermal camera. By the assistance of thermal imaging method air leak rate has been improved.
