Answer to Question 1

ANS: A
With BiPAP, inspiratory positive airway pressure (IPAP or pressure-supported ventilation) and expiratory positive airway pressure (EPAP or positive end expiratory pressure) are set.

Answer to Question 2

ANS: D
Clinical studies have shown that compared with spontaneous breathing (including that occurring during synchronized intermittent mandatory ventilation), PSV can result in a decreased respira-tory rate, increased tidal volume, reduced respiratory muscle activity, and decreased oxygen consumption.

Stevens-Johnson syndrome and Toxic Epidermal Necrolysis syndrome are life-threatening reactions that can result in death. Complications include permanent blindness, dry-eye syndrome, lung damage, photophobia, asthma, chronic obstructive pulmonary disease, permanent loss of nail beds, scarring of mucous membranes, arthritis, and chronic fatigue syndrome. Many patients' pores scar shut, causing them to retain heat.
