PURPOSE: We present a novel AUS implantation technique using a single perineal incision for single device placement or in combination with an inflatable penile prosthesis (IPP). Urinary and sexual dysfunction following the management of prostate cancer has a significant impact on the quality of life of our patients. While there are marginal changes in the prosthetic devices, we strive to reduce post-operative morbidity while maximizing efficacy. MATERIALS AND METHODS: We retrospectively reviewed the outcomes of 6 patients who underwent single perineal incision placement of a virgin AUS in 2014, 3 with simultaneous IPP placement...

Korotkoff sounds are known to change their characteristics during blood pressure (BP) measurement, resulting in some uncertainties for systolic and diastolic pressure (SBP and DBP) determinations. The aim of this study was to assess the variation of Korotkoff sounds during BP measurement by examining all stethoscope sounds associated with each heartbeat from above systole to below diastole during linear cuff deflation. Three repeat BP measurements were taken from 140 healthy subjects (age 21 to 73 years; 62 female and 78 male) by a trained observer, giving 420 measurements...

Yang Wang, Zhiwen Liu, Shaodong Ma
This paper proposes an unobtrusive blood pressure (BP) measurement system design with motion artifact (MA) compensation strategy as a potential surrogate to the traditional cuff-based sphygmomanometer for self-monitoring in less restricted environment. Approach: A dual-channel photoplethysmographic signal acquisition system is designed and implemented for the cuff-less BP measurement based on peripheral pulse transit time (PPTT) acquired from the forearm and wrist. Comprised of motion decision, singular spectrum analysis, PPTT calculation and BP measurement, a novel approach is proposed to realize BP measurement with suppressing MA interference...

M W P de Wolf, T van der Beek, A E Hamaekers, M Theunissen, D Enk
BACKGROUND: Ventilation through small-diameter tubes typically precludes use of a cuff as this will impede the necessary passive outflow of gas alongside the tube's outer surface. Ventrain assists expiration and enables oxygenation and normoventilation through small-bore cannulas or catheters, particularly in obstructed airways. A small-bore ventilation catheter (SBVC; 40 cm long, 2.2 mm inner diameter) with a separate pressure monitoring lumen and a cuff was developed. Efficacy of oxygenation and ventilation with Ventrain through this catheter was investigated in sealed and open airways in a porcine cross-over study...

This paper presents an oscillometric blood pressure (BP) measurement approach based on the active control schemes of cuff pressure. Compared with conventional electronic BP instruments, the novelty of the proposed BP measurement approach is to utilize a variable volume chamber which actively and stably alters the cuff pressure during inflating or deflating cycles. The variable volume chamber is operated with a closed-loop pressure control scheme, and it is activated by controlling the piston position of a single-acting cylinder driven by a screw motor...

REVIEW
Karim Lakhal, Stephan Ehrmann, Thierry Boulain
Although its reliability is often questioned, non-invasive blood pressure (NIBP) monitoring with an oscillometric arm cuff is widely used, even in shocked critically ill patients. When correctly implemented, modern arm NIBP devices actually can provide accurate and precise measurements of mean blood pressure as well as clinically meaningful information such as identification of hypo- and hypertensive patients and monitoring of response to therapy. Even in specific circumstances such as arrhythmia, hypotension, vasopressor infusion and possibly in obese patients, arm NIBP could be useful, contrary to widespread belief...

Nurses play an important role in identifying patients at risk for medical device-related (MDR) pressure injuries and preventing their occurrence. A prospective, descriptive study was conducted across 6 hospitals in Ankara, Turkey between December 2014 and June 2015 to assess nursing perceptions about and interventions used for the pre- vention of MDR pressure ulcers. A questionnaire was used to collect demographic information and data on experience with MDR pressure ulcers; in addition, participants completed a Nursing Interventions Form that included 10 statements regarding basic nursing interventions to prevent MDR pressure ulcers; answer options were I perform, I partly perform, I do not perform...

Current oscillometric devices for monitoring central blood pressure (BP) maintain the cuff pressure at a constant level to acquire a pulse volume plethysmography (PVP) waveform and calibrate it to brachial BP levels estimated with population average methods. A physiologic method was developed to further advance central BP measurement. A patient-specific method was applied to estimate brachial BP levels from a cuff pressure waveform obtained during conventional deflation via a nonlinear arterial compliance model...

PURPOSE: Inhibition of the renin-angiotensin system may have effects on vascular structure and function beyond the effects on blood pressure (BP) reduction. We studied the ability of a single arm cuff oscillometric method (Arteriograph, TensioMed, Hungary) to assess effects of antihypertensive treatment on BP and arterial stiffness. Furthermore, this technique was compared to pulse wave analysis and applanation tonometry (SphygmoCor, AtCor Medical, Australia). MATERIALS AND METHODS: Brachial and aortic BP, augmentation index (AIx), and carotid-femoral pulse wave velocity (PWV) was simultaneously assessed by both techniques in 71 untreated hypertensive patients...

BACKGROUND: Puncture-induced radial artery spasm (RAS) may extend the duration of coronary angiography (CAG) or cause transradial access failure. Flow-mediated dilatation (FMD), a widely-used noninvasive approach for assessing endothelial function, was reported to remove the entrapped radial sheath after percutaneous coronary intervention. Herein, the efficacy and safety of FMD in treating puncture-induced RAS before transradial CAG was investigated. METHODS: Ninety patients with puncture-induced RAS were randomized in a 1:1:1 ratio into three groups: FMD group was immediately treated with blockage of brachial artery blood for 5 min using a sphygmomanometric cuff and then rapid relief; NTG group was administered with 0...
