The "Torrstick": a ruler calibrated in millimeters of mercury for measurement of hydrostatic pressure.

We have designed and constructed a ruler ("Torrstick") calibrated in millimeters of mercury for the measurement of hydrostatic pressure differences. Marks are placed on a measuring stick every 1.34 cm, to afford the best compromise between a column of 0.9% saline solution and a column of blood. Several uses for this ruler are proposed, including the measurement of central venous pressure.

Utilization of image-derived computer-assisted stereotaxis in a community-based practice setting.

The success of a community-based stereotactic program is dependent upon community commitment, technological capability, referral base, patient/family support and, most importantly, proper patient selection. To develop a program of superior quality requires not only a substantial financial commitment, but also a basic philosophical approach which fully supports acquisition and education of support staff, physical plant renovation and an establishment of an expanding referral base. This report details the development of a highly sophisticated stereotactic program in Cedar Rapids, Iowa, a semirural community with a base referral population of approximately 300,000.

Blood pressure monitoring: automated oscillometric devices.

An understanding of the principles of blood pressure measurement with automated oscillometric devices (e.g., Dinamap) allows a user to realize the purpose and level of accuracy for which the equipment is designed. Good technique cells for various actions: (1) using a cuff of proper size (too large a cuff will generally work acceptably, but too small a cuff will yield erroneously high readings); (2) squeezing all of the residual air out of the cuff before applying it to the arm or leg; (3) wrapping the cuff snugly around the arm or leg; (4) instructing the patient to refrain from talking or moving and letting nothing press against the cuff during measurement; (5) keeping the cuff and heart at the same horizontal level. (6) When instrument malfunction is suspected, first checking the status of the patient (not the status of the instrument) to be sure that a clinical emergency is not causing the suspected "malfunction"; (7) repeating a reading several times when it is suspicious and, if necessary, modifying the measurement conditions by using, for example, different limbs or different cuffs until the question is resolved; and (8) remembering that a leak in the cuff, hoses, or connection can cause an unexpected malfunction.
