EGAN'S CH. 45 (EXAM 6) QUESTIONS AND ANSWERS ALREADY PASSED
To safely and effectively initiate and manage a mechanical vent, an RT must be able to: - Ventilator design, classification, & operation Appropriate clinical application of ventilatory modes Physiologic effects of mechanical ventilation & pulm. mechanics Four basic functions: - input power power transmission and conversion control system output (pressure, volume and flow waveforms) The power source for a vent comes from: - Electrical energy (energy= volts * amperes * time) Compressed gas (energy= pressure * volume) Characteristic of electrical energy: - Vents use voltage from an electrical line outlet normally 110-115 volts alternating current (AC) (60Hz) This AC volte may be reduced & converted to direct current (DC) DC source can then be used to power delicate electronic control circuits Some portable vents have a rechargeable battery Pneumatic energy (compressed gas) - Most modern ICU vents are pneumatically powered
