Breathing machines are widely used to evaluate respirator performance but they are
capable of generating only limited air flow patterns, such as, sine, triangular and square
waves. In order to evaluate the respirator performance in practical use, it is desirable
to test the respirator using the actual breathing patterns of wearers. However, it has
been a difficult task for a breathing machine to generate such complicated flow patterns,
since the human respiratory volume changes depending on the human activities and workload.
In this study, we have developed an electromechanical breathing simulator and a
respiration sampling device to record and reproduce worker’s respiration. It is capable of
generating various flow patterns by inputting breathing pattern signals recorded by a
computer, as well as the fixed air flow patterns. The device is equipped with a
self-control program to compensate the difference in inhalation and exhalation volume and
the measurement errors on the breathing flow rate. The system was successfully applied to
record the breathing patterns of workers engaging in welding and reproduced the breathing
patterns. 相似文献

The Occupational Safety and Health Administration (OSHA) mandate requiring medical information for respirator users provides the physician with little or no guidance as to what objective criteria may be valuable in assessing the worker's ability to use a respirator safely. Therefore, the purpose of this study is to use the results of clinical pulmonary function testing to predict performance time on maximal- and endurance-type exercise tests. Respirator mask wear reduced clinical pulmonary function measures from 7%-15% from mouthpiece controls. The resistances of the mask reduced forced vital capacity by an average of 11.6% (0.65 L); forced expiratory volume in 1 sec by 7.3% (0.33 L); and maximum voluntary ventilation in 15 sec by 7.4% (12.4 L/min). Stepwise linear regression analysis was used to determine the clinical pulmonary function measures that were the best predictors of work performance. The MVV.25 with the respirator was determined to be the best predictor of maximal exercise performance both with and without the respirator. The difference in peak inspired flow with and without the respirator was the best predictor of performance time with the respirator during the endurance walk to exhaustion. Recommendations are made to the physician for procedures for determining a worker's pulmonary capacity and calculating the effect of the respirator in reducing that capacity. This information then will allow the physician to determine safe levels of ventilation for a particular work task. 相似文献

A useful system to study the cardiopulmonary effects of respirators in the workplace would be reliable, portable, and lightweight and would not encumber the nose or mouth or require modification to the respirator. Twenty men using such a system (which measured ventilatory parameters by respiratory inductive plethysmography [RIP]) were studied. The subjects all performed their usual jobs which involved some work with and some without a respirator. Twelve subjects used airline respirators and eight used air-purifying respirators. The RIP equipment measurements included respiratory frequency, tidal volume (VT), minute ventilation (V), and heart rate (HR). The RIP data from 20 other subjects was lost because of equipment malfunction, primarily lead separation in those whose jobs involved climbing around large workpieces. In general, the workers' cardiopulmonary parameters increased during respirator wear, probably because of a combination of factors, including the increased exercise of most respirator-requiring tasks and the weight and heat stress associated with the respirator and protective clothing. When the ventilatory parameters with and without a respirator were compared at the same heart rates, no significant differences were noted in VT for the entire group. Respiratory frequency, however, and V increased with respirator wear. The effects of respirators alone were found to be commonly confounded in the workplace by changes in protective clothing, exercise requirements, and ambient heat stress. Further improvements in the portable RIP system are needed before it can be accepted as a reliable ventilatory measurement device in the workplace. 相似文献
