Mechanical Ventilation Endotracheal intubation and mechanical ventilation is indicated when patients have: Airway compromise Respiratory failure Ventilator Settings to be familiar with: Modes: AC, IMV, SIMV, PSV AC-always gives the patient a minimum number of breaths IMV and SIMV are weaning modes, we are letting the patient control more of their respirations (patient has more control) PSV (pressure support ventilation): inspiratory pressure is added to spontaneous breaths to overcome the resistance of the endotracheal tube or to increase the volume of spontaneous breaths. PSV may also be used as a stand-alone mode to facilitate spontaneous breathing. Rate-sets the minimal number of respirations Tidal Volume (VT)-the amount of air normally inhaled & exhaled during one respiratory cycle. FIO2- sets the percentage of oxygen given to the patient, remember 21% is room air. PSV--pressure support ventilation I:E-inspiratory to expiratory phase PEEP-positive expiratory end pressure; prevents collapse of small airways & alveoli at end expiration. Starts at 2.5 cm H20, maximum is10 cm H20. When is it indicated? In highly hypoxemic states (ARDS) and when decreased FIO2% is needed to avoid oxygen toxicity. Peak inspiratory pressure (PIP): pressure within the ventilator system, normal is 20-40 Important alarms—mean air pressure, above 20 cmH20 is high If pressure alarms are going off: May need suctioning The patient may be agitated and “biting” the ETT They may be experiencing bronchospasm. May be developing a condition called ARDS.
