exchange

 [eks-chānj´]
1. the substitution of one thing for another.
2. to substitute one thing for another.
gas exchange the passage of oxygen and carbon dioxide in opposite directions across the alveolocapillary membrane.
health care information exchange in the nursing interventions classification, a nursing intervention defined as providing patient care information to health professionals in other agencies.
impaired gas exchange a nursing diagnosis approved by the North American Nursing Diagnosis Association, defined as excess or deficit in oxygenation and/or carbon dioxide elimination at the alveolocapillary membrane (see gas exchange). Etiological and contributing factors include an altered oxygen supply, changes in the alveolar-capillary membrane, altered blood flow, and altered oxygen-carrying capacity of the blood. Defining characteristics include changes in mental status such as confusion, somnolence, restlessness, and irritability; ineffective coughing and inability to move secretions from the air passages; hypercapnia; and hypoxia. For specific medical treatments and nursing interventions, see airway clearance, ineffective; breathing patterns, ineffective; chronic airflow limitation; and anemia.

Regarding this type of exchange, not only do the exchangers sin and have to pay restitution but also those who give them money to keep and do what we saw earlier and then do not want to pay anything, saying that what [the exchangers] earn with their money and receive from those who pay in cash is enough as salary.
