The analysis looked at patients 65 and older (Medicare-eligible) from the CHAMPION trial and found that there was a 58% reduction in all-cause hospital readmissions (hospitalisation for any reason) and a 78% reduction in heart failure hospital readmissions when patients were managed with the CardioMEMS HF system compared to standard-of-care medical management. These findings suggest that use of the CardioMEMS HF system can significantly reduce the hospitals risk of government-imposed penalties that are designed to reduce patient readmissions within 30 days of treatment.. The CardioMEMS system uses a miniaturised, wireless monitoring sensor that is implanted in the pulmonary artery during a minimally invasive procedure to directly measure pulmonary artery pressure. Measuring pressure allows clinicians to proactively manage treatment with medication changes for patients with worsening heart failure before visible symptoms, such as weight and blood pressure changes, occur. The system allows ...

0054] FIG. 7 also illustrates that in some embodiments the pressure sensor 704 is located adjacent (e.g., next to or under) an exterior surface 714 of the housing 710. In this example, an exterior surface 722 of the pressure sensor 704 is coplanar with the exterior surface 714 of the housing. Thus, the external surface 722 of the pressure sensor 702 will be flexible (e.g., to couple pressure waves to the capacitive circuit 708) and biocompatible in this case. For example, the external surface 722 may comprise silicone or some other flexible biocompatible material. In addition, the housing 710 may be flexible and engaged with the capacitive circuit 708 in this case to assist in the coupling of pressure waves to the capacitive circuit 708. Also, the external surface 722 will form part of the hermetic seal for the device 702 here, along with hermetic sealing (e.g., via adhesive or welding) between the external surface 722 and the hermetic external surface 714 of the housing 710.

Over the years some medical studies have tried to better understand the internal behavior of human beings. Many researchers in this domain have been striving to find relationships between intra-vaginal temperature and certain female health conditions, such as ovulation and fertile period since womans intra-vaginal temperature is one of the body parameters most preferred in such studies. However, due to lack of a appropriate technology, medical research devoted to studying correlations of such body parameters with certain womans body phenomena could not obtain better results. This article presents the design and implementation of a novel intra-body sensor for acquisition and monitoring of intra-vaginal temperatures. This novel intra-body sensor provides data collection that is used for studying the relation between temperature variations and female health conditions, such as anticipation and monitoring of the ovulation period, detection of pregnancy contractions, preterm labor prevention, etc..

All sites were sampled during the dry season (February 2014). River discharge was measured upstream (5.3 m3 s−1 near site 1) and downstream (5.4 m3 s−1 near site 10) using depth transducers at rated cross sections. At site 1, stage height was measured every 15 min using a RuggedTROLL 100 pressure transducer that was corrected for atmospheric pressure changes (In-Situ Inc., Fort Collins, CO, USA). At site 10, the stage height was measured every 15 min with a pressure transducer connected to a Eureka Manta2 sonde (Eureka Water Probes, Austin, TX, USA). Rating curves were developed at both sites by measuring discharge using the area-velocity method on multiple occasions in 2011 and 2014 using either a handheld staff gauge or weighted measuring tape for depth and velocimeter for velocity or a HydroSurveyor (SonTek, San Diego, CA, USA). The stage height was converted to discharge using a rating curve developed for each site (39). Discharge measurements were averaged over a 10-day period before ...

A system and method for monitoring vehicle tire pressure. A tire monitor for each tire includes a pressure sensor for sensing tire pressure and a transmitter for transmitting a signal representative of the sensed tire pressure. A receiver for mounting on the vehicle receives the tire pressure signals. The transmitters and the receiver utilize code division multiple access (CDMA) for the tire pressure signals so that tire pressure signals transmitted simultaneously by the transmitters can be received by the receiver. A controller for mounting on the vehicle communicates with the receiver and collects and processes the tire pressure signals, and generates control signals for use in conveying tire pressure information to a vehicle occupant.

This invention provides a means of measuring tissue pressure in muscle compartments and other regions in humans and other animals. An appropriate length, for example, 6 to 12 inches of thin plastic tubing, typically less than 3 mm outside diameters, is prepared as a working part of the tissue pressure transducer. A portion of the plastic tubing including the thin wall section such as a bubble is inserted into the muscle tissue for which pressure measurement is desired to be made. A fluid is circulated through the tubing at a constant flow rate. When the internal pressure of the tubing is greater than the external pressure, the bubble expands and there is no increase in the flow resistance of the system. When the pressure on the outside exceeds the normal system operating pressure, the thin wall section or bubble contacts, resistance to flow increases, and the system pressure increases. This increase in system pressure is directly proportional to tissue pressure.

Rotor-stator interaction, a major source of high amplitude pressure pulsation and flow-induced vibration in the centrifugal pump, is detrimental to stable operation of pumps. In the present study, a slope volute is investigated to explore an effective method to reduce high pressure pulsation level, and its influence on flow structures is analyzed using numerical simulation. The stress is placed on experimental investigation of unsteady pressure pulsation inside the slope volute pump. For that purpose, pressure pulsations are extracted at nine locations along the slope volute casing covering sensitive pump regions. Results show that distinct pressure pulsation peaks at fBPF, together with nonlinear components are captured. These peaks are closely related to the position of pressure transducer and operating conditions of the pump. The improvement of rotational speed of the impeller results in rapid increase of pressure fluctuation amplitude at fBPF and corresponding root mean square (RMS) value ...

The use of multiple infusions through one cannula is an increasingly common practice in anaesthesia. High pressures in the line often lead to occlusion alarms and pump disconnection. In this study, we aim to determine the pressures generated in common 3-way infusion devices, using simple low-cost equipment available and currently in use in the operating theatre environment. We compared three different common and commercially available 3-way infusion devices that allowed multiple infusions through one cannula in vitro. One with anti-siphon valves, one without valves, and serial extension sets with side ports connected in series. An invasive blood pressure transducer was used to monitor line pressure. Seven different infusion rates were used to simulate different infusions. 3-way infusion devices with anti-siphon valves have 5.5 times the infusion pressures compared to devices without valves (P | 0.001). The highest pressures obtained across all devices were at the highest flow rate studied (400 ml/hr);

There are several means of getting information about intracranial pressure. These are only two of the methods in common use: the external ventriular drain and the parenchymal pressure transducer. The alternative, also presented here, is a clinical assessment. This chapter answers the question as to how one might monitor intracranial pressure, rather than asking whether one should (the indications for ICP monitoring being the subject of another chapter).

Coarctation of the aorta (CoA) accounts for 8%-11% of congenital heart defects, affecting tens of thousands of patients annually in the western world. Surgical or catheter-based treatments seek to alleviate the blood pressure gradient through the coarctation in order to reduce the workload on the heart. The pressure gradient is dependent on the anatomic severity of the coarctation: the greater the % of area reduction, the larger the pressure gradient. Furthermore, the pressure gradient is also greatly dependent on the flow rate and therefore the physiologic state of the patient: a small pressure gradient at rest can increase several-fold even in mild exercise conditions. The clinician can easily measure the pressure gradient through the coarctation under resting conditions, either by using a catheter-driven pressure transducer or a sphygmometer. However, measuring the pressure gradient under exercise conditions is more challenging since these conditions are not easy to replicate in the clinic. ...

The object of these experiments was to evaluate the hydrostatic pressure and hydraulic permeability of the tooth pulp in situ. A small hole was drilled through the enamel and dentin to the dentinal-pulpal junction in canines and third incisors of anesthetized dogs. A threaded cannula filled with mammalian Ringers solution was screwed into the hole and connected to a microsyringe and a pressure transducer of very low compliance.. Pressure was recorded when the cannula was first inserted into the hole; then small amounts of fluid were injected into the system or withdrawn from the system using the micro-syringe. The equilibrium pressure (Peq), measured after transients had disappeared, was fairly constant for a given tooth over long periods of time. Referred to tooth level (which was approximately heart level), Peq averaged 57 mm Hg (range 38 to 78 mm Hg) in the ten teeth tested. Superimposed upon the steady value was a random deviation (± 3 mm Hg), a hysteresis effect resulting in a higher ...

A rate adaptive cardiac pacer is described in which the impedance versus time information derived using impedance plethysmography or the pressure versus time information derived from a pressure transducer in a ventricular chamber is signal processed to recover a modulating envelope due to volume or pressure changes occasioned by respiratory activity. Either or both of the respiratory interval or respiratory depth may be combined in an appropriate rate control algorithm with other parameters also derived from the impedance versus time signal to develop a rate control signal for an implanted pacer.

Objective: The goal of this work was to demonstrate technical feasibility of automated balloon pressure management during REBOA in the pre-clinical setting. Methods: This paper presents an intelligent balloon management device which automates the balloon inflation process, preventing the possibility of balloon over or under inflation, optimizes inflation pressure and if indicated, deflates automating partial REBOA to allow distal organ perfusion. Edwards TruWave pressure transducers are used to monitor the blood pressure proximal and distal to the balloon, as well as the internal balloon pressure. A faux PID controller, implemented on an Arduino platform, is used in a feedback control loop to allow a user defined mean arterial pressure setpoint to be reached, via a syringe driver which allows intelligent inflation and deflation of the catheter balloon. Results: Ex vivo testing on a vascular perfusion simulator provided the characteristic behavior of a fully occluded aorta, namely the decrease of ...

The Abdominal Pressure Twin Sensors (APTS) for Q3 and Q6 dummies are composed of soft polyurethane bladders filled with fluid and equipped with pressure sensors. Implanted within the abdominal insert of child dummies, they can be used to detect abdominal loading due to the belt during frontal collisions. In the present study - which is part of the EC funded CASPER project - two versions of APTS (V1 and V2) were evaluated in abdominal belt compression tests, torso flexion test (V1 only) and two series of sled tests with degraded restraint conditions. The results suggest that the two versions have similar responses, and that the pressure sensitivity to torso flexion is limited. The APTS ability to detect abdominal loading in sled tests was also confirmed, with peak pressures typically below 1 bar when the belt loaded only the pelvis and the thorax (appropriate restraint) and values above that level when the abdomen was loaded directly (inappropriate restraint). Then, accident reconstructions ...

We previously reported the use of a catheter system to damage the tricuspid valve and create infectious endocarditis (IE) in an animal model. The current study aims to create a faint IE model suitable for antibiotic prophylaxis using a low bacterial inoculum. We also aim to explore a way to quantitatively assess valvular impairment and to predict the success of the IE models during catheterization. Ninety rabbits were assigned to two groups according to the density of bacteria inoculated (1 × 105 CFU for Group A and 1 × 104 CFU for Group B). A catheter system consisting of a polyethylene catheter and a guide wire were used to damage the valve. The catheter system was passed through the rabbits tricuspid valves under echocardiographic guidance. A pressure transducer was used to assess right atrial pressure (PRA) before and just after valvular damage to calculate the pressure alterations (ΔPRA). The animals in group A and B were divided into 3 subgroups according to the ΔPRA (0-5 mmHg for Groups A1

purpose. To determine whether topical treatment of mouse eyes with latanoprost alters intraocular pressure (IOP).. methods. In a masked study design, NIH Swiss mice received a 2-μL topical instillation of 0.00015%, 0.0006%, 0.0025%, or 0.01% latanoprost or vehicle (phosphate-buffered saline [PBS]). After 1, 2, or 3 hours, the animals were anesthetized, and a fluid-filled glass microneedle connected to a pressure transducer was inserted through the cornea into the anterior chamber to measure IOP. The reduction of IOP after latanoprost measurement was calculated by the comparison between treated and nontreated eyes in the same mouse. The effect of latanoprost after a single 0.01% dose was also measured at 6, 12, and 24 hours. As in the previous study, the identity of all eye drop solutions was masked.. results. In mouse eyes receiving topical PBS, the mean IOP was 14.8 ± 2.2 mm Hg (n = 173 males). There was no significant difference in IOP between male and female eyes and between right and left ...

Purpose: Retrospective studies from our laboratory have identified low cerebrospinal fluid pressure (CSFP) as a risk factor for glaucoma. The low CSFP will presumably be reflected in a proportionally lowered intracranial pressure (ICP). Unfortunately, there are no existing animal models to investigate the role of ICP and the glaucoma phenotype. In the current study, we developed a rat model that can be used to manipulate ICP, and eventually be used to study the role of ICP on optic neuropathy.. Methods: Brown Norway rats (n=3, retired breeders, age ,8 months, weight , 300 g) were surgically implanted with a 20 gauge cannula into the lateral ventricle. The cannula was held in place by dental cement and secured to the skull with 4 screws. An external 3 mm post was connected to PE60 tubing protected by a flexible metal tether. The tether was connected to a swivel mount that enabled movement within the cage. The tubing was attached to a pressure transducer connected to a computer that recorded ICP ...

After a fasting period of 16 h with free access to water, the pigs were anesthetized with 500 mg ketamine followed by 15 mg midazolam, given intramuscularly. Pigs were weighed, and an ear vein was cannulated to allow infusions of pentobarbital (2 mg · kg−1· h−1). Fentanyl bolus doses were given if needed (2-4 μg/kg). The trachea was intubated, and the lungs were artificially ventilated with an air-oxygen mixture, using a Cameco UV 705 respirator (Cameco, Sweden), with a frequency of 19 breaths/min, and 20 cm water pressure. The end-tidal carbon dioxide level was maintained between 4 and 5 kPa (Godart Capnograph Mark 11; E. Jaeger, Wuerzburg, Germany). Heart rate and blood pressure were measured continuously (Pressure Transducer, HP 78342A; Hewlett Packard, Boeblingen, Germany). Rectal temperature was measured continuously, and the temperature of the pig was maintained at 38°C with a heating blanket. The jugular vein was cannulated for infusion of fluids (2.5% glucose in 0.45% saline) and ...

Reactive oxygen species such as superoxide are involved in many cardiac diseases. Menadione is a superoxide donor that has varied effects upon the mechanical and electrical activity of cardiac muscle(Anderson & Dutta 1991; Choi et al, 2005). It has been suggested that its effects are associated with changes in intracellular Ca2+ but this has not been tested nor have simultaneous mechanical and electrical responses been recorded. The aim of this study was to test the hypothesis that the mechanical and electrical effects of menadione occur in the presence of dysfunctional intracellular Ca2+ regulation. Male Wistar rats 200-250g were killed, hearts removed and Langendorff perfused with a Krebs-Heinsleit solution at 37°C. Left ventricular pressure was monitored by an indwelling balloon connected to a pressure transducer and monophasic action potentials (MAPs) were recorded from the epicardial surface of the left ventricle. Hearts were alternately paced at 5Hz or allowed to intrinsically pace for 5 ...

TY - JOUR. T1 - Prolonged ambulatory monitoring of colonic motor activity in the pig. AU - Crowell, M. D.. AU - Musial, F.. AU - French, W.. AU - Kittur, D.. AU - Anderson, D.. AU - Whitehead, W. E.. PY - 1992/9. Y1 - 1992/9. N2 - The aim of this study was to develop a chronic model suitable for repeated, long-term studies of the interaction of behavior and colonic function in unrestrained pigs. Cecostomies were created in three 20-30 kg micropigs under general anesthesia. Fistulas were created by suturing the bowel to the abdominal wall. Recordings were made by passing a small (8F) solid-state pressure transducer through the fistula into the proximal bowel and connecting it to a battery-operated data logger worn in a vest on the pigs back. Cecostomies have remained patent and trouble-free for over 18 months. No serious infections have occurred. Preliminary data from a total of thirteen 24-h recording sessions showed 54% of all contractile activity to be in the 2-4 cpm frequency range. ...

The porous ceramic membranes described are used in the osmotic tensiometer, a humidity sensor to be applied in soil environments. This is the subject of part III. This application field implies the measurement of humidities close to 100%. Humidity sensors for this range are and will be an essential element of agriculture and horticulture in a world of increasing prices for clean, potable water. However, no adequate method exists yet when considering criteria as response time, endurance, reproducability and ease of use. A novel technology using a combination of dedicated polymer, a state-of-the-art ceramic membrane and a sensitive pressure transducer may give the desired result. This is the osmotic tensiometer. In chapter 9 several aspects of response time for application of the osmotic tensiometer under realistic field conditions are quantified in a transport model. This model is validated with experiments using a novel design of the osmotic tensiometer. Chapter 10 deals with the favorable ...

The peristaltic reflex can be evoked in the absence of input from the CNS because the responsible neural pathways are intrinsic to the intestine. Mucosal enterochromaffin cells have been postulated to be pressure transducers, which activate the intrinsic sensory neurons that initiate the reflex by secreting 5-HT. All of the criteria necessary to establish 5-HT as this transmitter have been fulfilled previously, except that no mucosal mechanism for 5-HT inactivation was known. In the current investigation, desensitization of 5-HT receptors was demonstrated to inhibit the peristaltic reflex in the guinea pig large intestine in vitro. At low concentration (1.0 nM), the 5-HT uptake inhibitor fluoxetine potentiated the reflex, but higher concentrations blocked it, suggesting that the peristaltic reflex depends on the 5-HT transporter-mediated inactivation of 5-HT. Specific (Na+ -dependent, fluoxetine-sensitive) uptake of 3H-5-HT by intestinal crypt epithelial cells was found by radioautography. mRNA ...

Differential Pressure Gauge- The piston-type differential pressure gauge provides a simple visual warning. When 15 psi (1.03 bar) differential pressure is reached, the gauge indicator moves from green to red zone. This warning will prevent premature cartridge change-out. Water Sight Glass- The water sight glass provides an easy means to detect water in the sump. The weighted ball, visible in the sight glass, will float only when water is present. The floating ball is an indication water should be drained from the housing to prevent both cartridge contamination and water traveling downstream from the housing.. ...

In the proposed approach, the subjects hand is pressed against the surface resulting in an uncontrolled pressure application and imprecise information of pressure location. The device consists of an array of pressure sensors interspersed with low cost visible-light and infrared miniature sources and cameras. The pressure sensors give information on the applied pressure, while the multispectral imaging is used to map a subjects vasculature. This map is processed together with pressure data to suppress misleading noise and accurately estimate a subjects blood pressure. The measurements are processed through advanced machine learning and optimization techniques to account for noise and vessels hidden by the pressure sensors to generate robust output. Noise is further mitigated through a differential electrocardiogram, generated by having the subject place both hands on the surface. To improve the performance of the design, a cost function will be minimized over the parameters of interest (e.g. ...
