Eighty attempts at placing suction catheters in the left main bronchus were analysed by studying chest radiographs. When angled catheters were used via a tracheostomy tube the success rate was 75%; the rate fell to 15% when straight tubes were used through an orotracheal tube. Assessment and control of the tube length was found to be important to avoid kinking and subsequent obstruction of the ...

We present an interesting case of a complete vanishing of the left main bronchus in a lung transplant recipient who had a successful outcome due to acute respiratory support with venovenous extracorporeal membrane oxygenation in order to perform airway dilation.

Recommended by Jörn Altmann This paper presents a simplified method for signal level clearance evaluation in each place of signal reception up to threshold for a given portable TV receiver device. It describes briefly the structure of transmission system considering the " 1Seg " structure of ISDB-T. The preliminary laboratory test was made before the field tests to verify the main features of h...

The main objective of regression testing is to test the modified software during maintenance phase of Software Development Life Cycle. An easiest strategy to regression testing is to retest all test cases in a test suite, but due to limitation of resources and time constraint, it is not efficient to implement. Test case prioritization technique increases the effectiveness of regression testing ...
