Question

1 pts Question 11 The nurse cares for a client on mechanical ventilation. The tidal volume (V) is set at 12 mL/kg. Which possible result MOST concerns the nurse? O Hypercapnia. O Barotrauma. O Hypoventilation. O Increased Positive end expiratory pressure (PEEP).

Answer 1

Ans) 11) Barotrauma

Explaination:

- The tidal volume is about 6-8 mL/kg of ideal body weight for patients with healthy lungs. For unhealthy lungs, such as in ARDS or ALI, 4-6 mL/kg is used as a protection strategy for the lungs. For example, the set tidal volume for a patient whose height is 5 feet 10 inches and weighs 400 pounds will be the same as for a patient with the same height but weighs 180 pounds.

- Barotrauma is a complication of positive pressures ventilation and is related not only to pressure but also to volume. Dynamic hyperinflation is the major aetiologic factor of barotrauma. Transpulmonary pressure, tidal volume and PEEPi are the main determinants of hyperinflation. Diagnosis is both clinical and radiological. Pneumothorax or tension pneumothorax must be suspected in all forms of barotrauma as possible dangerous complications.
