complex ectopic beat

SEE: under beat.

complexed prostate-specific antigen

(kŏm-plekst′, kom′plekst″) ABBR: cPSA. A laboratory test that assays levels of prostate-specific antigen bound to alpha-1-chymotrypsin. The cPSA test is slightly more useful in the detection of prostate cancer than the simple PSA test but may not be as accurate as assessments of serum unbound or free PSA.


(kŏm-plĕk′shŭn) The color and appearance of the facial skin.

complex regional pain syndrome, type 1

Reflex sympathetic dystrophy.

complex regional pain syndrome, type 2



(kŏm-plī′ăns) 1. Adherence (2). 2. Alteration of size and shape in response to application of force, weight, or release from force. The lung and thoracic cage of a child may have a high degree of compliance as compared with that of an older person.

dynamic c. A measure of the ease of lung inflation with positive pressure.

effective c. Patient compliance during positive-pressure breathing using a tidal volume corrected for compressed volume divided by static pressure.

frequency-dependent c. A condition in which pulmonary compliance decreases with rapid breathing; used to identify small airway disease.

myocardial c. The ease with which the heart muscle relaxes as it fills with blood.

pulmonary c. A measure of the force required to distend the lungs.

static c. A volume-to-pressure measurement of lung distensibility with exhalation against a closed system, taken under conditions of no airflow. It can be represented mathematically as: Tidal volume/Pplat-total PEEP (positive end-expiratory pressure).

tubing c. The ability of ventilator tubing to expand when pressurized. It is calculated by closing the ventilator circuit and measuring the volume under pressurization.

ventricular c. Distensibility or stiffness of the relaxed ventricle of the heart.

compliance program

A corporate or institutional program that provides guidelines for the ethical and legal behavior of employees. It is used to disseminate knowledge about, supervise, and enforce the conduct of health care employees, specifically their adherence to federally mandated rules that regulate health care fraud, waste, and abuse.

complicating disease

A disease that occurs during the course of another disease.


(kŏm″plĭ-kā′shŭn) [L. cum, with, + plicare, to fold] An added difficulty; a complex state; a disease or accident superimposed on another without being specifically related, yet affecting or modifying the prognosis of the original disease, e.g., pneumonia is a complication of measles and is the cause of many deaths from that disease.
