RESPIRATORS IN INTENSIVE-CARE MEDICINE - BASIC INFORMATION

Microprocessor-controlled intensive care ventilators combine controls of pressure, flow, volume, and timing to generate various breathing mo des and differentiated breathing patterns that will meet the respirato ry needs of the patient. This is essential when respirator-supported v entilation is performed. Graphic representation of ventilatory paramet ers is another important feature, facilitating subtle adjustments. The future may bring even more desirable options to improve monitoring of respiratory mechanics and make management easier. Modern ventilators differ less in technical features than do the accessories with differe nt options. Most of these options are costly without any corresponding benefit in terms of treatment or diagnosis; nevertheless, future upgr ading possibilities should be borne in mind when hardware is purchased . There is no ideal ventilator, and the success of respiratory treatme nt will therefore continue to be dependent on the patient's underlying disease and the therapist's level of training and experience rather t han on the choice of respirator.
