conclusions we found the magnetic field assistant device to be an accurate, radiation-independent jig for close passing of guide wire after close reduction of femoral fracture. it can reduce the need for radiation during placement of guide wire for closed intramedullary nailing of the long bones. more studies are required to improve and evaluate the technique and equipment. results outcomes of ...

This paper presents an experimental investigation into the compression behavior of shape memory alloy hybrid composites (SMAHC) subjected to quasi-static loading taking into account of rotation effects of shape memory wire in basalt continuous filament (BCF) direct roving epoxy composite. Two types of specimen prepared, the BCF direct roving reinforced epoxy composite filled with shape memory w...

Recently, spirometers have become available for use within general practice as an alternative to peak flow meters. This study investigates whether practice assistants, after comprehensive training, can effectively carry out spirometry with patients suffering from asthma and other chronic obstructive pulmonary diseases. A scoring system, consisting of 20 items, was devised to determine the effec...

The efficiency of the carbon dioxide absorption by soda lime was determined in the following way. (1) " Circle " breathing. In six experiments, a subject breathing through a Waters canister fully packed with 425 g of fresh soda lime was connected to a closed circuit spirometer as described by Erikson et al. (1951). The expired air then passed the canister before entering the spirometer where th...

STUDY OBJECTIVES Laboratory-based spirometry is the "gold standard" for the assessment of lung function, both in clinical and research protocols. These spirometers, however, are neither practical nor affordable for home-based monitoring or studies that collect data in multiple locations. Traditionally, peak flowmeters have been used, but they have important limitations. DESIGN Based on data f...

BACKGROUND An objective method to evaluate thoracoabdominal movement is needed in daily clinical practice to detect patients at risk of hypoventilation and to allow for timely interventions in neuromuscular diseases. The clinical feasibility, reliability, and validity of a newly developed method for quantifying respiratory movement using fiber grating sensors, called the Respiratory Movement Ev...

1. THE subject which I have the honour to bring before this Society, is the consideration of the functions of the organs of respiration, with reference both to health and disease, as deduced from the result of an extensive research. Before commencing this investigation, it is advisable to ascertain what has been already done by others upon the same subject, in order that the observer may be dir...

In the past, many attempts (1, 2, 3, 4, 5, 6, 7, 8, 9, 10) have been made to discover the origin of postoperative pulmonary complications. Nearly all of these attempts have been concerned with the study and analysis of hospital records. The results of this method of study have been disappointing. In the present research, the question has been analyzed from a new angle. The aim has been to measu...

OBJECTIVE To assess the effects of different oxygen concentrations and flow rates on the measurement errors of neonatal pneumotachometers in heated and unheated situations and to develop correction factors to correct for these effects. DESIGN Prospective laboratory study. SETTING Outpatient clinic with equipment in a standardized setting. SUBJECTS Neonatal pneumotachometers. INTERVENTIO...
