What form of ventilation is the recommended support for acute respiratory disorders?

A 45-year-old, 73-inch-tall, 200 lb male patient is admitted to the emergency department with an exacerbation of myasthenia gravis

The respiratory therapist assesses the patient and finds the patient's maximum inspiratory pres-sure is 15 cm H2O and his vital capacity is 1200 mL. It is decided that the patient requires venti-latory support. The most appropriate ventilator settings for this patient are which of the follow-ing? a. Pressure support ventilation (PSV) 5 cm H2O, continuous positive airway pressure (CPAP) 10 cm H2O, FIO2 0.50 b. Pressure-controlled continuous mandatory ventilation (PC-CMV), f = 16 breaths/min, peak inspiratory pressure (PIP) = 35 cm H2O, positive end-expiratory pressure (PEEP) 3 cm H2O, fractional inspired ox-ygen (FIO2) 0.45 c. Noninvasive positive pressure ventila-tion—bilevel positive airway pressure (NPPV—BiPAP), f = 14 breaths/min, in-spiratory positive airway pressure (IPAP) = 28 cm H2O, expiratory positive airway pressure (EPAP) = 5 cm H2O, FIO2 0.30 d. Volume-controlled intermittent mandatory ventilation (VC-IMV), f = 12 breaths/min, tidal volume (VT) = 725 mL, PSV 5 cm H2O, PEEP 5 cm H2O, FIO2 0.24

A to deliver or TD pipets are designed to:

A. Allow the user to remove a portion of the sample in the tip for better accuracy. B. Be vigorously tapped against the test tube after all the liquid is removed. C. Drain by gravity. D. Be refilled or rinsed out with the appropriate solvent after the initial liquid
