NSG233.07.01.01 Mechanical Ventilation Noninvasive positive-pressure ventilation High-frequency oscillatory support ventilators Volume-cycled ventilators Positive pressure ventilators a method of positive-pressure ventilation that can be given via facemasks that cover the nose and mouth, nasal masks, or other oral or nasal devices such as the nasal pillow (a small nasal cannula that seals around the nares to maintain the prescribed pressure). deliver very high respiratory rates (i.e., 180 to 900 breaths/min) that are accompanied by very low tidal volumes and high airway pressures (hence the name high-frequency oscillatory support ) deliver a preset volume of air with each inspiration. inflate the lungs by exerting positive pressure on the airway, pushing air in, similar to a bellows mechanism, and forcing the alveoli to expand during inspiration. Pressure-cycled ventilators delivers a flow of air (inspiration) until it reaches a preset pressure, and then cycles off, and expiration occurs. SIMV APRV PSV PAV delivers a preset tidal volume and number of breaths per minute. a time-triggered, pressure-limited, time-cycled mode of mechanical ventilation that allows unrestricted, spontaneous breathing throughout the ventilatory cycle. applies a pressure plateau to the airway throughout the patient-triggered inspiration to decrease resistance within the tracheal tube and ventilator tubing. provides partial ventilatory support in which the ventilator generates pressure in proportion to the patient’s inspiratory efforts. BiPAP Pressure support ventilation Continuous mandatory (volume or pressure) ventilation CPAP offers independent control of inspiratory and expiratory pressures while providing pressure support ventilation (PSV). applies a pressure plateau to the airway throughout the patient-triggered inspiration to decrease resistance within the tracheal tube and ventilator tubing. the ventilator delivers a preset tidal volume or pressure at a preset rate of respirations. provides positive pressure to the airways throughout the respiratory cycle. NSG233.07.01.02 Nursing support during Mechanical Ventilation The nurse maintains the patient's head of the bed so that it is elevated 30° or higher unless contraindicated to prevent the risk of aspiration. Increased adventitious breath sounds may indicate a need for suctioning. Which of the following would be a nursing diagnosis for a patient receiving mechanical ventilation? Select all that apply. Ineffective airway clearance

Impaired gas exchange Impaired verbal communication Which of the following would be potential complications of patients receiving mechanical ventilation? Select all that apply. Ventilator problems Alterations in cardiac function Barotrauma *** Based on the assessment data, potential complications may include the following:  Ventilator problems (increase in peak airway pressure or decrease in pressure or loss of volume)  Alterations in cardiac function  Barotrauma and pneumothorax  Pulmonary infection and sepsis  Delirium and postintensive care syndrome Nursing support during weaning Which of the following is true regarding nutritional support when weaning mechanical ventilation? Select all that apply. Adequate protein intake is important increasing respiratory muscle strength. Consultation with dietitian or nutrition support team should be arranged soon after the patien admitted. Daily nutrition should be closely monitored. Put the following in order: The patient is gradually removed from the ventilator Patient is removed from the endotracheal or tracheostomy tube Patient is weaned from oxygen therap Which of the following are methods of weaning mechanical ventilation? Select all that apply.
