PS/2 port connections are extremely rare today, but when they are used, they are generally used for a barcode scanner in what is called a "keyboard wedge" interface. This simply means the barcode scanner's cable has a Y split at the end and a PS/2 keyboard is connected to one end and the other end is connected to the POS computer. This allows (wedges) both the barcode scanner and keyboard to use the same PS/2 port. Many computers today no longer have a PS/2 port. Please see our interface type buying guide if you are unsure over what interface type you need for your barcode scanner. And if you are still unsure, simply give us a call. It would be great to hear from you.

IJV and see the top of oscillating venous column Measurement of JVP • Two scale method is commonly used • A horizontal scale at the top of the oscillating venous column in IJV cuts the vertical scale at the sternal angle gives JV pressure in cm of water • Normally JV pressure does not exceed 4 cm above the sternal angle • Since RA is approximately 5 cm below the sternal angle , the jugular venous pressure (RA mean pressure) is corresponds to 9 cm • By way of conversion , normal mean JV pressure does not exceed 7 mm Hg (9 cm column of water / 1.3 =6.9) • Elevated JVP : JVP of >4 cm above sternal angle . Elevated JVP • Increased RVP and reduced compliance: Pulmonary stenosis Pulmonary hypertension Right ventricular failure RV infarction • RV inflow impedance: Tricuspid stenosis / atresia RA myxoma Constrictive pericarditis Elevated JVP • Circulatory overload : Renal failure Cirrhosis liver Excessive fluid administration • SVC obstruction • COPD Kussmual's sign • Mean jugular venous pressure increases during inspiration as a result of impaired RV compliance. • Constrictive pericarditis • Severe right heart failure • RV infarction • Restrictive cardiomyopathy Abdominal -Jugular Reflux • Hepatojugular reflux – Rondot (1898) • Apply firm pressure to periumbilical region for 10 -30 sec with patient lying comfortably and breathing quietly while observe JVP • Normally JV pressure rises transiently(15 sec) to Positive AJR • Incipient and or compensated RVF • LVF with volume overload • Tricuspid regurgitation • False Positive AJR ( without CCF) COPD Systemic vasoconstriction Increased sympathetic tone Severe anaemia Gaertner's method • Measurement of JVP by examining the veins on the dorsum of the hand • When patient sitting or lying at a 45‘ elevation , arm slowly and passively raised from dependant position until the vein collapses • Height of the limb above the level of sternal angle at which vein collapses represents the venous pressure • When venous pressure is normal , veins of hand collapse at the level of sternal angle Cardiac tamponade • JVP is usually elevated
