While the therapist provides ventilation using a BVM, the patient's airway resistance increases and pulmonary compliance decreases. How will these changes in lung characteristics affect the delivered volume?
 
  A. The delivered volume will decrease.
  B. The delivered volume will increase.
  C. The delivered volume will remain essentially the same.
  D. The delivered volume will fluctuate considerably.

Question 2

The therapist is in a one-rescuer, prehospital resuscitation situation, and is using a bag-valve-mask to provide volume to the victim's lungs. What can the therapist do to increase the volume delivery to the victim's lungs?
 
  A. Employ the face-and-thigh-squeeze technique.
  B. Squeeze the bag more rapidly.
  C. Use two hands to squeeze the bag.
  D. Switch to nonself-inflating resuscitation bag.

Answer to Question 1

ANS: A
A. Correct response: During ventilation with a BVM in use, if pulmonary compliance decreases and/or airway resistance increases, the delivered volume could decrease. Because a BVM is essentially a volume-controlled ventilator, an increased resistance or decreased compliance should not effect tidal volume, unless more leaks develop or the bag distends. However, to overcome these changes in lung characteristics, the therapist needs to use two hands to squeeze the BVM, assuming that another rescuer can hold the mask in place to create a seal during ventilation.
B. Incorrect response: See explanation A.
C. Incorrect response: See explanation A.
D. Incorrect response: See explanation A.

Answer to Question 2

ANS: A
A. Correct response: Several studies have concluded that one-rescuer resuscitation with a BVM is typically ineffective, and numerous suggestions have been made to improve ventilation provided by BVM. The face and thigh squeeze, or FATS, technique has been recommended. This method is used in one-rescuer, prehospital care to increase delivered volume. The rescuer kneels and places the head of the victim between his knees. One hand of the rescuer holds the mask and provides the head-tilt/chin-lift by pulling the patient's mandible upward. The rescuer's remaining hand squeezes the bag against his own thigh in an attempt to maximize bag deflation.
B. Incorrect response: See explanation A.
C. Incorrect response: See explanation A.
D. Incorrect response: See explanation A
