Information About Radiology
Category Respiratory Support Sleep Medicine Typical Use Provide continuous positive airway pressure to treat obstructive sleep apnea and support ventilation. Description A device that delivers a constant positive airway pressure through a mask to splint the upper airway open during sleep, reducing apneas and improving daytime symptoms and cardiovascular outcomes in obstructive sleep apnea. CPAP … Read more
Category Wound Closure Typical Use Noninvasive adjustable skin approximation for linear incisions. Description An adhesive based external device with interlocking straps that approximates wound edges without staples or sutures, allowing adjustable tension and easy removal while reducing puncture related infection risk and improving cosmetic outcomes for selected incisions.
Category Interventional Radiology Endovascular Typical Use Deliver guidewires, coils, or embolic agents to distal vessels. Description A very small diameter, flexible catheter used to access tortuous or distal vascular territories during embolization, angioplasty, or neurointerventional procedures, providing a conduit for microguidewires and therapeutic devices while minimizing vessel trauma.
Category Airway Management Typical Use Visualize vocal cords for endotracheal intubation. Description An instrument with a handle and blade (rigid or video equipped) used to visualize the larynx and vocal cords to facilitate placement of an endotracheal tube during airway management. Traditional direct laryngoscopes provide a line of sight view, while video laryngoscopes use a … Read more
Category Vital Sign Monitoring Typical Use Measure arterial blood pressure. Description An inflatable cuff paired with a pressure gauge (aneroid or digital) used to measure systolic and diastolic arterial blood pressure noninvasively. The cuff is placed around the upper arm at heart level and inflated to occlude arterial flow, then slowly deflated while listening for … Read more
Category Cardiology Diagnostic Typical Use Exercise provoked assessment of ischemia and functional capacity. Description A motorized treadmill integrated with ECG monitoring and blood pressure measurement used to perform graded exercise tests to detect inducible ischemia, assess exercise tolerance, and guide cardiac rehabilitation planning under supervised conditions.
Category Ophthalmology Diagnostic Typical Use Estimate refractive error by observing reflexes from the retina. Description A handheld optical instrument that projects a streak or spot of light into the eye while the clinician observes the red reflex movement to estimate refractive errors and guide objective refraction, particularly useful in nonverbal patients and pediatric examinations. Retinoscopy … Read more
Category Surgical Access Typical Use Establish pneumoperitoneum and access for laparoscopy. Description A Veress needle or trocar is used to insufflate the abdomen with carbon dioxide and create initial access for laparoscopic surgery, providing a safe working space for visualization and instrument manipulation. Entry technique varies (open Hasson technique, Veress needle, or optical trocar) and … Read more
Category Endoscopy Urology Typical Use Visualize bladder and urethra; perform interventions. Description A rigid or flexible endoscope inserted through the urethra to visualize the urethra and bladder mucosa, obtain biopsies, remove stones, or place stents; cystoscopy is used for hematuria evaluation, recurrent urinary tract infections, and bladder tumor surveillance. Flexible cystoscopes allow office based procedures … Read more
Category Diagnostic Typical Use Listen to heart, lung, and bowel sounds. Description An acoustic instrument consisting of a chest piece, tubing, and binaural earpieces used to listen to internal body sounds such as heartbeats, breath sounds, and bowel activity. Clinicians use it to assess cardiac rhythm, detect murmurs, evaluate lung fields for wheeze or crackles, … Read more
