A patient receiving pressure control ventilation is being ventilated with a following vent. settings: Rate 14 bpm ,  I-time 0.8 sec. ,  PIP 30 cm H2O,   PEEP  5 cm H2O What is patient’s PaW? ( Mean airway pressure )    I.   8.94 cm H2O II.  9.66 cm H2O III. 7.99 cm H2O IV. 10.4 cm H2O

The set rate was increased to 15 breaths/min.   Four hours later the patient’s nurse calls to tell you that the ventilator is alarming. You enter the room and the low pressure and low volume alarms are triggering. What should be assessed at this time?   Select as MANY as indicated

A time-cycled constant flow generator is set up with a flow of 35 L/min and an inspiratory time of 1.7 seconds. What is the approximate VT?   A. 750 ml (0.75 L) B. 990 ml (0.99 L) C. 1900 ml (1.90 L) D. 1200 ml (1.20 L)
