The results of research into a biochemical marker for depression are presented. The research was carried out on a normal population in a primary care setting. Cholesterol levels were identified as the blood marker for anxiety and depression. The Hamilton Rating Scale for Depression was chosen to identify depression. Those with low cholesterol scored significantly higher on the Hamilton Rating Scale for Depression.
The assessment of mechanical ventilator performance is a complex task requiring measurement of a number of different transducers under a variety of conditions. The use of dedicated testing equipment can alleviate the complexity of the experimental apparatus. This paper assesses the accuracy and versatility of the Biotek VT-1 and VT-2 dedicated ventilator testers. Results show that the testers perform within the manufacturer's specifications and have the required flexibility to be used in investigating faults reported with ventilators.
