Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Source: Rachel Liu, BAO, MBBCh, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Tube thoracostomy (chest tube placement) is a procedure during which a hollow tube is inserted into the thoracic cavity for drainage of fluid or air. Emergency chest tube insertion is performed for definitive treatment of tension pneumothorax, traumatic hemothorax, large-volume pleural effusions, and empyemas. Irrespective of the cause of air and fluid accumulation in the pleural space, the...

Strategies of Self-Presentation II: Self-Verification

Self-verification is a fundamental psychological drive wherein individuals seek affirmation of their self-concept from others, striving for consistency between their internal self-view and external perceptions. This drive operates even when the self-concept is negative, influencing interpersonal behavior and feedback preferences in complex and often counterintuitive ways. Unlike the self-enhancement motive, which seeks positive evaluations, self-verification prioritizes coherence and...

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.
FAQs
The evidence used in Tube Position Verification depends on the tube and the anatomical location it should occupy. Airway tubes can be checked through exhaled carbon dioxide detection, whereas some enteral tubes may be assessed through aspirate and pH testing. Radiographic imaging provides another option when direct visualization is required. Matching the check to the tube makes verification clinically relevant.
Exhaled carbon dioxide detection is particularly relevant for airway tubes because it supplies evidence linked to airflow from the respiratory system. In this context, the finding helps assess whether the tube has entered the intended airway rather than the esophagus. Its role is therefore tube-specific: it addresses airway placement, not every possible tube location or clinical situation.
For some enteral tubes, clinicians can examine aspirate and perform pH testing as part of the verification process. This approach uses material obtained through the tube as evidence about its location, rather than relying on airway signals. Because it applies to some, rather than all, enteral tubes, this check does not replace other methods when imaging is required.
Radiographic imaging becomes important when direct visualization is required to establish where a tube lies. It can provide anatomical evidence that other checks may not supply, particularly when the relevant question concerns the tube’s position within the body rather than an airway signal or aspirate characteristic. In practice, this makes imaging a complementary verification route for selected clinical circumstances.
The safety value of verification comes from distinguishing intended placement from clinically hazardous alternatives. The process is designed to help identify entry into the esophagus, respiratory tract, or surrounding tissues, depending on the tube and target location. Detecting these mismatches before use can reduce risks that include aspiration, inadequate ventilation, tissue injury, and ineffective treatment.
Tube Position Verification supports several clinical interventions, but the consequence of an error varies with the tube’s purpose. For airway management, incorrect location can compromise ventilation; for nutrition or medication delivery, it can make treatment ineffective or contribute to aspiration. Verification therefore links anatomical confirmation with the planned intervention before the tube is used.
