The respiratory therapist review the ventilator flow sheet for a post-op patient. The vent settings have not changed during the past 24 hours. The peak and plateau pressure were recorded as follows: Time:                                            0700am        0900am         1100am Peak Pressure:                                 28                   33                    47 Plateau Pressure:                             22                   22                    22   What is the problem?

What happens to the inspiratory pressure in PRVC mode if lung compliance decreases?  

What type of waveform pattern does PRVC use?  

Strategies to reduce auto-PEEP in mechanically ventilated patients with obstructive lung disease include which of the following?1. Use high inspiratory flows (60 to 100 L/min).2. Apply extrinsic PEEP.3. Use high VT values of 8-10 mL/kg4. Use high respiratory rates (>25/min).

Hyperventilation should generally be avoided during mechanical ventilatory support. Exceptions to this rule include: 1. Failure of other methods to reduce intracranial pressure. 2.  Trying to calm an agitated patient.  3. Hypokalemia causing cardiac arrhythmias.

The nursing students are making a list of interventions for people who need to limit their intake of sodium. In order to demonstrate understanding of the teaching, what should the students list as the most impactful change for this population?

What is the likely consequence if Automatic Tube Compensation (ATC) is set for a size 6 trach when the patient actually has a size 6 ETT?

A patient is on mechanical ventilation with a tidal volume (VT) of 550 mL, a peak inspiratory pressure (PIP) of 25 cmH₂O, plateau pressure of 20 cmH₂O, a positive end-expiratory pressure (PEEP) of 5 cmH₂O, and a FiO2 of 50%. What is the dynamic compliance of the patient’s lungs?

A nurse educator is teaching a class about the role of minerals in the diet. The nurse determines that teaching was effective when a student makes what statement about minerals?
