Otterbein/Grant CRNA Patient Positioning Review

Which of the following are goals of operative positioning?

Please fill answer below_______

The only position in which the West zones of the lung are normal in the operating room is:

Please fill answer below_______

Select all of the following physiological changes that apply to a patient in the supine position:

Your patient is in Trendelenberg position. You understand that their FRC is inversely proportional to the steepness of their positioning.

In the lithotomy position, respiratory changes are dependent on the extent to which the ____ are flexed on the abdomen

In extreme lithotomy positioning, compliance and tidal volumes _ while airway pressures __.

What patient position is most preferable for ventilation?

When the patient is in the sitting position but the lower extremities are flexed at the hip, abdominal contents shift upwards against the diaphragm. This causes a change in FRC similar to the change seen in which position?

Patients in the lateral position are susceptible to _______ because closing volumes occur above FRC with closing occurring earlier in the dependent lung

Your patient is in the lateral position, you know that you should consider ______ your TV and utilizing a higher RR to prevent declines in oxygenation.

In the lateral position, the compliance of the dependent lung:

In the prone position with the abdomen hanging free, FRC:

In the prone position, what causes improvement in oxygenation?

You have successfully intubated your patient in the supine position. Your patient is having a procedure on their shoulder, upon raising them to the seated position what do you anticipate happening to your patient's blood pressure?

Neuromuscular blockade increases venous return.

Your patient is under general anesthesia in the sitting position. What do you expect to happen to their preload and stroke volume?

Opioids and volatile agents slow the heart rate, decreasing cardiac output and blood pressure. In healthy patients, MAP is maintained by compensatory increases in heart rate and ______

___________ can be unrecognized in the lithotomy and Trendelenburg positions, because MAP can appear normal despite volume deficit d/t large amount of venous return.

The sitting position increases cerebral blood flow.

Which position puts the patient at greater risk for venous air embolism?

Tourniquet pressure > _____ mmHg or longer than 2 hours increase the risk of peripheral nerve injury.

Treatment of a venous air embolism is via removing the air via aspiration through a multiorifice central venous catheter.
