Exam 17: Mechanical Ventilation of the Neonate and Pediatric Patient

Over the last 90 minutes,the therapist has obtained three arterial blood samples from an arterial line inserted in a neonate receiving mechanical ventilation and being monitored by capnometry.The PaCO? values were as follows: (1)47 mm Hg,(2)46 mm Hg,and (3)47 mm Hg.How should the therapist evaluate the following capnogram? B

Which of the following factors need to be considered for HFV ventilator circuits? I.Time for gas egress during exhalation II.Circuit compliance III.Endotracheal tube size IV.Intrinsic timing mechanisms

The following pressure-volume loop was obtained from a patient receiving mechanical ventilation in the pressure support mode.What type of problem does this ventilator graphic represent?

During high-frequency ventilation,as the diameter of the ETT increases,what happens to the delivered tidal volume under the same pressure settings?

How is the minute ventilation decreased when a patient is being weaned from HFOV?

The therapist is conducting a ventilator check for a neonate and makes the following notations on the ventilator flow sheet: •PEEP: 5 cm H₂O •Peak inspiratory pressure (PIP): 25 cm H₂O •Mandatory rate: 15 breaths/minute •FiO₂: 0.35 On the basis of these observations,what should the therapist recommend for this neonate?

How is the radiographic assessment of neonatal lung volume performed?

Which of the following modes of ventilation attempts to maintain a minimum target tidal volume with a constant pressure by manipulating the inspiratory flow?

What frequency defines high-frequency modes of ventilation?

What is a frequent requirement when employing the low-volume strategy while ventilating a neonatal patient with pulmonary interstitial emphysema by HFV?

On the basis of the following pressure-volume loop,what ventilator setting change should the therapist make?

Enhanced diffusion in HFV is a function of which of the following factors?

During HFOV,which of the following factors has a direct influence on a neonate's delivered tidal volume?

During HFOV manipulation of which of the following components establishes the continuous distending pressure?

Which of the following adjustments should the therapist consider to improve ventilation on a patient undergoing HFV?

The therapist notices that gas exchange has dramatically improved in a neonate undergoing HFOV.However,weaning has not been implemented accordingly.What are the consequences of failing to quickly wean a neonatal patient from HFV?

When airway pressure release ventilation is used,what physiologic process occurs as the higher pressure is released and the lower is achieved?

During volume-controlled ventilation,which of the following factors influences the peak inspiratory pressure?

On the basis of the following flow/time scalar,which of the following conditions has developed?

Which of the following factors influences the gas volume compressed in the ventilator circuit?
