Which of the following are side effects of Heliox therapy? I. volume induced lung injury results when heliox is used with ventilator not FDA approved for it II. causes erroneous flowmeter readings when giving bronchodilator with heliox III. oxygen analyzer must be used to ensure FiO2 being delivered to patient IV.  thermal conductivity of helium can cause hypothermia for infants receiving heliox via an oxyhood

Your pt is being ventilated with a nasal mask to relieve dyspnea.  He has a long history of COPD and hypercarbia.  What is the goal of noninvasive ventilation in this setting with regard to the ABGs?

Paralytics are used to facilitate invasive procedures, to prevent movement, ensure the stability of artificial airways, and facilitate less conventional mechanical ventilation modes. 

Which of the following contribute to the difficulty of ventilating burn and smoke inhalation victims? I. pulmonary edema and airway obstruction II. muociliary action is impaired III. occlusion of smaller airways leading to atelectasis IV.  frequently develop ARDS and pneumonia V. high fluid requirements of resuscitation
