A patient is receiving continuous mechanical ventilation via the Siemens 300A.  Settings and parameters are as follows: Mode PRVCVT   700 mLRR  14FiO2  0.65Pb  700 mmHgCuff pressure 29 mmHg pH    7.36PaCO2 42 torr HCO3-  22 mEq/LPaO2 95 torrSaO2   96% What if anything should be done regarding the cuff pressure (be specific)?

What is the primary purpose of PEEP

In pressure control ventilaiton, what changes occur to volume and pressure if the patient’s compliance decreases or Raw increases?

Using the diagram below, how would you describe the inspiratory flow?

If the set VT is 500 mL, using the following diagram:  the PIP is cmH2O, the Pplat is cmH2O, the Raw is cmH2O/L/sec, the PEEP is cmH2O, and the Cstat is mL/cmH2O.

Define intrinsic PEEP.

PEEP accomplishes its primary purpose by .

A mechanically ventilated patient is going to be placed on pressure support ventilation following an acceptable spontaneous weaning trial. The patient is a 5’9″ male who weighs 185 lb. During volume-controlled continuous mandatory ventilation (VC-CMV) his average peak inspiratory pressure (PIP) was about 26 cm H2O and the plateau pressure (PPlateau) was 11 cm H2O. What initial pressure support level should be set?

Calculate the inspiratory to expiratory (I:E) ratio for a ventilator that is set to deliver 500 mL at a frequency of 15 breaths/min with a flow rate of 60 L/min.
