Strategies for ventilatory support.
Since the introduction of manual positive pressure ventilation during the Copenhagen polio epidemic of 1952, a range of mechanical devices and methods of ventilatory support have been developed to provide life-saving respiratory therapy to critically ill patients. In addition to the development of the equipment hardware to enable effective mechanical ventilation, there has been a gradual realis...
متن کاملRespirator performance rating tables for nontemperate environments.
Respirator performance rating tables have been constructed for hot, humid (29 degrees C, 95% RH); hot, dry (49 degrees C, 30% RH); and cold, dry (-32 degrees C, 70% RH) conditions. These tables convey expected wearer performance percentages compared to unmasked workers for various mask elements and work rates. The hot, humid condition was found to be the most severe overall. Many table entries ...
متن کاملDiscontinuing mechanical ventilatory support.
The ventilator discontinuation process is a critical component of ICU care. Ongoing ventilator dependency is caused by both disease factors (eg, respiratory, cardiac, metabolic, and neuromuscular) and clinician management factors (eg, failing to recognize discontinuation potential and inappropriate ventilator settings/management). A multispecialty evidence-based task force has recommended a ser...
متن کاملWeaning from ventilatory support.
PURPOSE OF REVIEW In intubated patients, mechanical ventilation offers essential ventilatory support, while the respiratory system recovers from acute respiratory failure. Yet, invasive mechanical ventilation is associated with risks and complications that prolong the duration of mechanical ventilation and increase the risk for death. Therefore, safely weaning the patient from the ventilator as...
متن کاملBreathing simulator of workers for respirator performance test
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 t...
