Ruppel Ch 8 Pediatric Pulmonary Function Testing Questions with Answers What's a popular example of a thoracoabdominal motion analysis? - Answer -respiratory inductive plethysmography (RIP) What is respiratory inductive plethysmography (RIP)? - Answer -uses respiratory tracings to monitor movement from the rib cage and abdomen simultaneously As each band______ (with inspiration), the coils are stretched, which alters the cross sectional area of the bands and changes the inductance of the coiled wire - Answer -
expands As passive _______ occurs, the bands relax and the voltage signal drops, with the patterns producing a sinusoidal tracing - Answer -exhalation The movement of what two things are monitored simultaneously? - Answer -rib cage & abdomen Both components independently contribute to what? - Answer -lung volume The sum of the rib cage and abdomen signals determine what? - Answer -TV What is impulse oscillometry (IOS)? - Answer -mini loudspeaker is placed proximal to the devices flow sensor and produces forced oscillations of flow with a range of frequencies IOS measures what? - Answer -Raw of small and large airways What is the interrupter technique (Rint)? - Answer -passive tidal breathing but the cycle is interrupted multiple times Rint measures what? - Answer -Raw Measurement of what are techniques now used in children? - Answer --exhaled nitric oxide (eNO) -nasal nitric oxide The measurement of eNO has been proposed as an index of what? - Answer -airway inflammation (like asthma) What was the first attempt at obtaining forced flows in infants and dates to the late 1970s? - Answer -partial forced flow -volume (F -V) What is the rapid thoracoabdominal compression (RTC) test? - Answer -the childs chest is mechanically squeezed or hugged by an inflated jacket. Techniques have been developed to raise the volume of the infants lungs before a RVRTC. This may be accomplished by doing what? - Answer -stacking inspirations or raised volume technique For this maneuver, a bias flow of air is provided to the child during _______, the exhalation port is simultaneously occluded, raising the intrathoracic pressure and volume in the child's lungs, once inflated the child is told to exhaled - Answer -inspiration A pressure of what is required to inflate the infants lungs to near TLC? - Answer -+30 cmH2O The advantage of this method compared with partial forced flows is what? - Answer -
expired volume is nearly an FVC measurement The volume expired in 0.5 seconds or 0.75 seconds can be calculated and is similar to what? - Answer -FEV1 As with the RTC technique, forced deflation techniques also produce what? - Answer -
maximal expiratory F -V curves (MEFV) The method is exactly _______ to the positive pressure generated during the RTC method. - Answer -opposite Instead, a ______ pressure is applied to the airway opening, and the lungs are deflated quickly - Answer -negative This method is only used in what infants? - Answer -intubated infants in PICU What is the most common type of PFT performed in the pediatric population? - Answer -
spirometry For adults, the primary goals of spirometry are what? - Answer --identify presence of obstructive defect or restrictive flow -degree of abnoramilty -response to a bronchodilator Introduce spirometry to children at a ______ age - Answer -young
