Using the above patient scenario 1: Task: 2.  Calculate the patient’s static compliance

Patient Scenario 1: You are managing a 65-year-old 5′ 10″ male patient with a history of chronic obstructive pulmonary disease (COPD) who was admitted with acute respiratory failure. He is currently on a mechanical ventilator in volume control mode. Here are his ventilator settings and measurements: Mode: Volume Control (VC) Tidal Volume (Vt): 400 mL Respiratory Rate (RR): 16 breaths per minute Flow: 60 L/min PEEP: 10 cmH2O PIP: 40 cmH2O Plateau Pressure: 35 cmH2O FiO2: 40% Recent ABG Results: pH: 7.25 PaCO₂: 65 mmHg PaO₂: 90 mmHg HCO₃: 26 mEq/L SaO₂: 97% Task: 1. Calculate the patient’s ideal body weight  

When is applied PEEP advocated in the presence of auto-PEEP?

In severe cases of pneumothorax, the mediastinum and trachea:

An 80-kg (176-lb) patient is being ventilated in pressure control mode. During a ventilator check, the therapist notes that the compliance has decreased from 40 mL/cm H2O to 35 mL/cm H2O. What effect will this change in compliance have on volume?

A ventilator has separate rate and VT controls. If you set a VT of 600 ml and a respiratory rate of 12/min in the continuous mandatory ventilation mode, what will the minute ventilation be?

Using the above patient scenario 1: Task: 3.  Calculate the patient’s airway resistance

What variable is a parameter that starts the inspiratory phase of a positive pressure breath?

If the low pressure alarm goes off on the vent, which of the following should you consider: 1. Patient disconnect 2. Leak in the vent circuit 3. Patient obstruction 4. Cuff leak

While observing a patient receiving ventilatory support, you notice that some delivered breaths are begun or ended by the machine, whereas others are begun and ended by the patient. Which of the following modes of ventilatory support is in force?
