Discuss the disadvantages and complications associated with the iron lung type of negative pressure ventilator.
What will be an ideal response?
Disadvantages and complications associated with the iron lung type of negative pressure ventilator are (1) poor patient access and (2) potential for a decreased cardiac output known as "tank shock". Since the iron lung encloses the patient, it restricts access to the patient for routine health care. Tank shock may result from a decreased venous blood return to the right atrium.
