Mechanical Ventilation
What does a PaO2 of 60 mmHg signify?
When is a patient who is mechanically ventilated suctioned?
As needed
To keep the patient safe during transport, what should the nurse do?
What are some of the adverse events that can occur due to disordered swallowing?
Which ventilator setting is monitored closely in patients receiving volume-controlled ventilatiion and is dependent on the lung's compliance and resistance?
Peak inspiritory pressure (PIP)
What are the adverse effects associated with using PEEP for a mechanically ventilated patient?
Decreased cardiac output
Increased intracranial pressure
Barotrauma
What are the benefits of a closed suctioning device?
Reduces symptoms of hypoxemia
Aids in maintaining oxygenation
Maintains PEEP
What positions should the patient who is mechanically ventilated avoid?
Flexion and extension of the head
Which medications are often given to mechanically ventilated patients for pain?
Fentanyl and Morphine
When a patient receives volume intermittent mandatory ventilation (VIMV) who has a total respiratory rate of 55 breaths per minute and shallow breathing, which complication would the nurse worry about?
Atelectasis
If a patient airway becomes obstructed, what method is used to reinstate the airway?
Head-tilt/chin-lift
Why do nurses suction shallowly instead of deeply?
Deeper suctioning has shown no benefit
What kind of trauma occurs when lung tissue injury is induced by local or regional overdistending volume?
What medication may be given to sedate the patient or reduce anxiety if they are mechanically ventilated?
Propofol
What does CPAP do?
It provides pressure at end-expiration, which prevents alveolar collapse and improves the functional residual capacity and oxygenation
What would be an advantage of a nasotracheal intubation?
It facilitates the swallowing of oral secretions
What assessments would the nurse complete on the mechanically ventilated patient?
Breath sounds, BP, heart rate, work of breathing
What kind of trauma occurs when alveolar injury or rupture occurs as a result of excessive pressure, excessive peak inflating volume, or both?
Barotrauma
If the idea is that the patient needs deep sedation or therapeutic paralysis, which medication is given for paralysis, and what would be given beforehand?
What order would the nurse expect to see to help prevent ventilator dyssynchrony in a patient being changed over to pressure-controlled inverse-ratio ventilation due to acute respiratory distress syndrome?
Sedation
When would a tracheostomy tube be used?
For long-term mechanical ventilation
What orders would the nurse expect to see on the care plan for a patient who was recently intubated to prevent complications?
Lovenox daily
Sedation holidays daily
Spontaneous breathing trial
70-100 mmHg
Which ventilator setting allows spontaneous breaths between mandatory breaths?
Intermittent mandatory ventilation
What assessment findings would show the patient is ready to wean off the ventilator before a weaning trial starts?
Adequate oxygenation
Cause of mechanical ventilation has been resolved
Hemodynamic stability
