PEDIATRIC MECHANICAL VENTILATION

Mechanical requirement depend on all EXCEPT:

• Type of surgery 
• Length of Surgery 
• Patient Position
• Tidal volume

What is physiological PEEP ____ and what does it do?

• 1-2 cm H20; Maintain alveoli patency
• 6-10 cmH20; increase Tidal volume
• 3-5 cm H20; push oxygen down to the lungs
• 3-5 cm H20; maintain alveoli patency   

If Respiratory rate is too high, the risk include all the following EXCEPT:

• Inadequate expiratory time
• Breath Stacking
• Development of Intrinsic PEEP
• Prolonged Expiatory time

Ventilators have two major functions?

• Volume; SIMV
• Volume; Pressure
• Pressure; PSV-Pro
• Barotrauma alert; Volume alert

What can happen if the cuff pressure is too low?

• Nothing higher is better
• It will break
• Tissue damage
• Aspiration

What can happen if the cuff pressure is too high?

• Nothing higher is better
• It will break
• Tissue damage
• Aspiration

Which of the following patients would be appropriate for pressure support (PS).

• Ventilated and sedated patient that is unresponsive.

• A Gift of Hope patient being prepared for the OR

• A patient that is ready to be weaned off of the ventilator

• A ventilator dependent spinal cord injury patient with a paralyzed diaphragm.

Which of the following is true?

• Positive End Expiratory Pressure (PEEP) keeps the alveoli open during exhalation.

• Allows for more lung recruitment.

• Is a common ventilator mode.

• Is considered normal when set at +5, in most patients.

The nurse suspects respiratory failure secondary to hypoventilation in a patient with which condition?

• anxiety
