Artificial Airways69

Unit I Lecture

QuestionAnswer
Tracheostomy: Tube of equal or _______ kept at bedside for emergency reinsertion? Smaller size
Tracheostomy: Tapes not changed for at least __ hours after insertion? 24
First change by physician no sooner than __ days after tracheostomy? 7
Indicated when head and neck manipulation is risky. Nasal ET Intubation
Surgical procedure performed when need for an artificial airway is expected to be long-term Tracheostomy
Obtain portable chest x-ray to confirm tube location? Adults 3-5cm above carina.
Obtain ABGs within __ minutes after intubation to determine oxygenation and ventilation status. 25
Stay with patient and maintain airway, Support ventilation, Secure help immediately, If necessary, ventilate with BVM and 100% O2. Incorrect Tube Placement Mngmt
Normal arterial tracheal perfusion is estimated at? 30 mmHg
Cuff pressure should be maintained at __ to __ mm Hg? 20-25
Change in mental status (e.g., confusion), anxiety, dusky skin, dysrhythmias? Hypoxemia
Use of accessory muscles, hypoventilation with dusky skin, hyperventilation with circumoral / peripheral numbness / tingling. Respiratory distress
Inflate cuff with minimum amount of air to form seal. Minimal Leak Technique
Tissue forms in __ to __ hours . Opening will close in several days without surgical intervention? 24 to 48
What is the treatment for Respiratory Acidosis? Improve Ventilation
Used to treat hypoxemia caused by respiratory, cardiovascular, or nervous system disorders. Oxygen
Always give _____ agent before Paralytic agent. Sedative
Rapid, concurrent administration of a paralytic agent and a sedative agent during emergency airway management. Rapid Sequence Intubation
Initial best way to check tube placement. End-tidal CO2 (Chest X-ray next)
Monitor ETT placement Q ___ to ___ hours? 2;4
Most common sign of hypoxemia is _______. Restlessness
Assess pt routinely to determine need for suctioning, but do not suction routinely. Maintain Airway Patency
Oral care q2hrs will decrease the risk of this by decreasing sub-glottic secretions. Ventilator Associated Pneumonia
If an artificial is in use HOB should be at 30 to ___ degrees. 45
Anytime you deflate a cuff you must ______ first. Suction (<120 mmHg)
Regulate rate, depth, and other characteristics of ventilation, tuned to match patient. Mechanical Ventilation
RR x TV Minute Ventilation
Used primarily in acutely ill patients, pushes air into lungs under positive pressure during inspiration. Positive Pressure Ventilation
Ventilator does all the WOB. Controlled Mandatory Ventilation (CMV)
Delivers breath at set rate per minute and set VT, independent of patient’s ventilatory efforts, Patient performs no WOB and cannot adjust respirations to meet changing demands. Controlled Mandatory Ventilation (CMV)
Delivers preset VT at preset frequency, when patient initiates a spontaneous breath, present VT is delivered. Assist-Control Ventilation (AC)
Complication with Assist-Control Ventilation. Respiratory Alkalosis
Delivers preset VT at preset frequency in synchrony with patient’s spontaneous breathing, etween ventilator-delivered breaths, patient is able to breathe spontaneously Synchronized Intermittent Mandatory Ventilation (SIMV)
What are the 4 modes of mechanical ventilation. CMV, AC, SIMV, PSV
Positive pressure applied to airway only during inspiration. Pressure Support Ventilation (PSV) Caution for hypoventilation
Positive pressure applied to airway during exhalation, exhalation remains passive, but pressure falls to preset level > 0, often 3 to 20 cm H2O. Helps keep alveoli open. Positive end-expiratory pressure (PEEP)
Pressure delivered continuously during spontaneous breathing. Continuous Positive Airway Pressure (CPAP)
Two levels of positive pressure support, Higher inspiratory positive airway pressure, Lower expiratory positive airway pressure along with oxygen. Bi-level positive pressure (Bi-PAP)
Word for fighting the ventilator. Ventilator Disynchrony
Air can escape into pleural space from alveoli or interstitium, accumulate, and become trapped –pneumothorax. Barotrauma
Relates to lung injury that occurs when large tidal volumes are used to ventilate noncompliant lungs, results in alveolar fractures and movement of fluids and proteins into alveolar spaces. Volutrauma
