|August 7, 2013
Summary
Most chest radiographs in the intensive care unit (ICU) show normal findings. Abnormal chest X-rays often do not lead to changes in patient care decisions.
Area of Science:
- Radiology
- Intensive Care Medicine
- Clinical Decision-Making
Background:
- Chest radiography is frequently utilized in intensive care units (ICUs).
- Understanding the diagnostic yield and impact on clinical decisions is crucial for optimizing resource allocation and patient management.
Purpose of the Study:
- To determine the prevalence of clinical abnormalities on chest radiographs in ICU patients.
- To assess the relationship between radiographic findings and subsequent medical care decisions.
Main Methods:
- Prospective cohort study of ICU patients.
- Daily assessment of imaging tests, including chest radiographs, over a defined period.
- Interpretation of radiographs by intensivists and correlation with changes in medical care.
- Statistical analysis using the chi-squared test.
Main Results:
- 106 patients and 447 imaging tests were analyzed, with 425 being anteroposterior chest radiographs.
- An average of 4.01 radiographs per patient were obtained.
- 79.3% of requested radiographs were normal; 35.2% of abnormal radiographs did not alter medical care.
Conclusions:
- The majority of chest radiographs performed in the ICU setting reveal no significant clinical abnormalities.
- Radiographic abnormalities identified in the ICU do not consistently lead to modifications in clinical management.

01:30Radiological Investigation I: X-ray and CT
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...
01:20Imaging Studies for Cardiovascular System III: X-Ray
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Respiratory assessment is a cornerstone of nursing assessments, crucial for the early detection of patient deterioration. This evaluation transcends routine procedures, representing a critical skill nurses must master to ensure optimal patient care.
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...

01:26Endoscopic Studies II: Thoracocentesis
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
