A patient is on continuous mechanical ventilation via a Puritan-Bennett 840. Upon entering the room, the respiratory therapist notes that the low volume alarm is sounding.  Which of the following should the respiratory therapist check?I. Drainage bottlesII. ET cuffIII. Kinked tubeIV. Medication cups

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.
