Abstract:
Although conventional radiography is still the first diagnostic imaging approach to respiratory disease, CT is proving to be invaluable as an adjunctive procedure in characterizing nasal and thoracic pathologic findings. CT eliminates superimposition of overlying structures and offers superior contrast resolution as compared with conventional radiography. These advantages allow for more precise characterization and localization of lesions and are invaluable for guiding rhinoscopic, bronchoscopic, and surgical procedures.

01:30Radiological Investigation II: MRI and Ventilation Perfusion Scan
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...

Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...
01:20Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
