Special Diagnostic Studies
| Question | Answer |
|---|---|
| Special Diagnostic Studies Electroencephalography | - the brain produces electrical activity measured as tiny fluctuations in voltage. - through the scalp - procedure is like an EKG |
| Special Diagnostic Studies Electroencephalography | - this electrical current is amplified and recorded on tracing paper. - The EEG data is combined with other clinical assessments, to diagnose neurological disorders. |
| Special Diagnostic Studies Electroencephalography/Indications | * brain tumors * traumatic brain injuries * retardation *loss of brain function * epilepsy/ seizures * evaluation of sleep disorders |
| Special Diagnostic Studies Pulmonary Angiography/Defined | - is the most definitive test for diagnosing a pulmonary embolism. |
| Special Diagnostic Studies Pulmonary Angiography/Clinical | - pressures in the various cardiac chambers can also be measured during this procedure. |
| Special Diagnostic Studies Pulmonary Angiography/Indications | - high clinical suspicion of pulmonary embolism - intermediate/indeterminate V/Q scan |
| Special Diagnostic Studies Pulmonary Angiography/Procedure | - the catheter is inserted in the femoral artery. - contrast medium is injected and multiple x-ray films to identify any filing detects. |
| Special Diagnostic Studies Ultrasonography of the Heart(Echocardiogram)/ Defined | - noninvasive method for monitoring cardiac performance |
| Special Diagnostic Studies Ultrasonography of the Heart(Echocardiogram)/ | - uses Doppler color flow. - mapping two dimensional and M Mode echocardiography - asses ventricular function - including left ventricular volume and ejection fraction |
| Special Diagnostic Studies Ultrasonography of the Heart(Echocardiogram)/Indication | - valvular disease or dysfunction - myocardial disease - abnormalities of cardiac blood flow - abnormal heart sounds |
| Special Diagnostic Studies Ultrasonography of the Heart(Echocardiogram)/Infants Indications | - Tetra logy of Fallot - Coarctation of the Aorta - Transportation of the great vessels - ASD, VSD,PDA |
| Special Diagnostic Studies Intracranial Pressure Monitoring/Defined | - cerebrospinal fluid (CSF) circulates freely around the brain and spinal cord.(protect tissue) |
| Special Diagnostic Studies Intracranial Pressure Monitoring/Performed | - to track the dynamics inside the skull. * volume pressure * wave pressure * cerebral perfusion pressure |
| Special Diagnostic Studies Intracranial Pressure Monitoring/Normal Value | - normal value is = 5-10mm Hg |
| Special Diagnostic Studies Intracranial Pressure Monitoring/Clinical | - recommend treatment if ICP > 20mm Hg - patent hyperventilated = Paco2= 25=30 torr. |
| Special Diagnostic Studies Intracranial Pressure Monitoring/Causes | * intracranial tumors * abscesses * meningitis * cerebral edema *subdural hematoma |
| Special Diagnostic Studies Intracranial Pressure Monitoring/Measured Ventricular Catheter | - ventricular catheter- inserted through a burr hole through the skull. |
| Special Diagnostic Studies Intracranial Pressure Monitoring/Measured Subarachnoid bolt | - consist of metal screws with a sensor chip that is inserted through a hole drilled into the subdural or subarachnoid space. |
| Special Diagnostic Studies Intracranial Pressure Monitoring/Measured Epidural Sensor | - consist of placement of a fiber optic sensor, radio transmitter or tiny balloon in the epidural space through burr hole in the skull. |
| Special Diagnostic Studies Intracranial Pressure Monitoring/Cerebral Perfusion Pressure | - pressure gradient that determines cerebral perfusion Formula = CPP = (MAP - ICP) |
| Special Diagnostic Studies Intracranial Pressure Monitoring/Exhaled Nitric Oxide | - measured exhaled nitric oxide concentration (FEno) in patients exhaled breath. |
| Special Diagnostic Studies Intracranial Pressure Monitoring/Exhaled Nitric Oxide/Indication | - used to monitor the asthma patient response to anti-inflammatory (corticosteroid )treatment |
| Special Diagnostic Studies Intracranial Pressure Monitoring/Exhaled Nitric Oxide/Decrease | - a decrease in FEno suggests decrease airway inflammation. |
| Special Diagnostic Studies Intracranial Pressure Monitoring/Exhaled Nitric Oxide/Procedure | - measured using a handheld device that provides accurate reproducible and measurement fractional exhaled nitric oxide. |
