Lung function test (LFT) is a good picture of how much air moves in and out of lung and how efficiently oxygen is moved in and carbon dioxide is moved out. The published guidelines for measuring PEF by American thoracic society provide no precise recommendations about the speed of inspiration preceding expiration and the appropriate duration of the post inspiratory pause. Although long post inspiratory pauses (> 3s) are generally not used, pauses of 3s). Whereas according to American thoracic society, pause of 3s inspiratory pauses are not recommended. So the study was to find out which...

Physiotherapists have the set goals of early weaning of the patient on mechanical ventilator, maintenance of bronchial hygiene, increasing the arousal of the patient, correcting the respiratory pattern for Patients with neurological insults and on mechanical ventilator. The three potential respiratory disabilities in these patients are - inability to ventilate, inability to cough, and risk of aspiration. Ventilatory insufficiency is mainly related to weakness or failure of the inspiratory muscles. Cough insufficiency is related to inspiratory, expiratory, and upper-airway dysfunction. And the...

This book contains a collection of papers dealing with various aspects of the biology and aquaculture of the large branchiopod crustacea; the Anostraca, Conchostraca, and Notostraca.

Additional manuscripts contributed by colleagues who were unable to attend are also included. A special feature of this volume is a checklist of the Anostraca, including information on distribution, location of type material, taxonomic problems, and literature...

The book documents the physical-chemical distribution of heavy metal in biotic and abiotic components with reference to hydrological characteristics of East Berbice-Corentyne Coast, Guyana. Besides heavy metal concentrations increased in water and sediment samples of the polluted sites. It also provide information on the bioaccumulation of heavy metals and its associated histopathological perturbations were studied in various tissues of M. cephalus collected from polluted and compared with the fish collected from less polluted of Corentyne coast. The presence of large lipid droplets in liver...
