A patient is currently on CMV with the following ventilator settings and ventilator waveform: AC/VC Rate – 14 breaths/min Set VT – 450 ml PEEP – +10 cm H2O FIO2 – 0.50     What should the respiratory care practitioner suspect?

The following are variables that causes a breath to begin during mechanical ventilation: I. Negative pressure II. Flow III. Time IV. Pressure Limit 

During mechanical ventilation, which classification causes a breath to end? 

What airway is used short term by paramedics and in surgery that sits above the esophagus?

A patient in severe acute lung injury (ALI) is currently on the following ventilator settings: Mode – AC/VC Total Rate – 20 breaths/min Rate –  20 breaths/min Exhaled VT – 340 ml VT – 350 ml VE – 6.8 L/min PEEP – 10 cm H2O PIP – 50 cm H2O FIO2 – 0.80 Plateau – 45 cm H2O The patient’s physician wants to place the patient on APRV. What P-High should be started on the new mode?

A patient has a cardiac output of 6 L/min and a heart rate of 70 bpm. What is his stroke volume?

What condition would cause a high-pressure alarm to be triggered while on CMV?

An intubated patient receiving conventional ventilation has orders for high frequency oscillatory ventilation. Where should the therapist set the mean airway pressure on the new mode? Mode –  AC Total Rate – 20 breaths/min Rate – 20 breaths/min Exhaled VT – 350 ml Pressure – 30 cm H2O VE – 7 L/min PEEP – 10 cm H2O PIP – 30 cm H2O FIO2 – 1.0 MAP – 17 cm H2O

What part of the pleura-vac should the respiratory therapist assess for an active pneumothorax?

A patient is now orally intubated on CMV secondary to head trauma due to MVC. The patient’s ICP  is at 15 mmHg and the physician would like the therapist to hyperventilate the patient to help decrease the ICP. Hyperventilation should be accomplished to bring PaCO2 levels between:
