A system for controlling patient sedation and spontaneous breathing intensity includes a ventilator system that delivers ventilation to the patient. The system further includes a spontaneous breathing control module configured to determine a first spontaneous breathing intensity at a first sedative status of the patient, and a second spontaneous breathing intensity at a second sedative status of the patient. A sedation/breathing relationship is then defined between spontaneous breathing intensity and sedative status for the patient based on the first and second sedative statuses and the first and second spontaneous breathing intensities. The spontaneous breathing control module then receives a desired spontaneous breathing intensity for the patient and determines a desired sedative status that achieves that desired spontaneous breathing intensity based on the sedation/breathing relationship.

1. Low level exercise is frequently used to assess cardiac and pulmonary function. This study examines the differences in both metabolic and respiratory patterns between the sitting and supine position.. 2. Six normal male subjects were studied in both positions during four levels of exercise (12.5, 25, 37.5 and 50 W). Oxygen consumption (Vo2), carbon dioxide production (Vco2) and minute ventilation (Ve2) were greater when sitting as were the ventilatory equivalents to O2 (Ve2/ Vo2) and CO2 (Ve2/ Vco2).. 3. Respiration was compared at equivalent workloads; the greater minute ventilation observed during sitting was due to greater tidal volumes (Vt) and mean inspiratory flows (Vt/Vi,). Expiratory time (Te) was longer and inspiratory duration shorter under most conditions when sitting.. 4. When breathing patterns were compared at similar degrees of minute ventilation, Vt, Te and Vt/Ti were greater when sitting, while respiratory frequency (fr) was slower. ...

This study will evaluate the effectiveness of a flexible belt device in guiding patient breathing during computed tomography (CT)-guided needle biopsy. When patients undergo CT scanning to help guide the physician during a tissue biopsy, they are usually asked to hold their breath while the scan is taken of certain parts of the body. When the first scan is completed, the patients are allowed to breathe, and are then asked to hold their breath again while the needle is advanced towards the tissue to be biopsied. Since body organs and tissues move with breathing, this study will try to stop the patients breathing at the same place in the breathing cycle to ensure that the biopsy target stays still and in the same place. This study will see if the flexible belt, used with a computer screen that charts the patients breathing, will improve the patients ability to stop breathing at the same place in the breathing cycle before and during the biopsy.. Patients 18 years of age and older who have a ...

The SleepCube BiLevel ST device is designed to enhance the breathing of patients with spontaneous respiration. Unlike ventilators, it will not completely take over the breathing for the patient, but instead helps a patient who has chronic respiratory failure, difficulty breathing, or obstructive sleep apnoea; it is administered via a mask and is not invasive.. The device automatically synchronises with the patients respiratory pattern, cycling between IPAP and EPAP (breathe in and breathe out).. The BiLevel ST can also be set to a timed mode, where the clinician sets the BPM (breaths per minute) and %IPAP; or it can be set to a combination of Spontaneous and Timed operation, where the unit cycles in response to the patients breathing rate, but switches to the timed operation if the patient fails to take a breath within the timed interval.. ...

In emission tomography, the process of image reconstruction has evolved since the utilization of the filtered back projection algorithm (FBP). Nowadays, iterative techniques incorporating statistical knowledge of the photon emission process has produced much interest among researchers, not only for the improvements achieved in image quality, but also by the possibility of incorporate corrections factors, like scattering, attenuation, etc. One of the problems that has not been discussed in depth is the incorporation of correction methodologies due to patient breathing, which produces blur regions in lungs and cardiac images. Solutions like respiratory gating, that synchronize the breathing cycle of the patient and the data acquisition process, or correlated dynamic PET techniques that use external radioactive markers and list mode data, have been tested with improvements over the spatial activity distribution in lungs lesions, but with the disadvantages of requiring extra hardware or more expensive

Philips Respironics patent US7168429B2 describes variable breathing as a breathing control layer in the auto CPAP, that monitors the flow signal to determine whether the patient is experiencing erratic breathing, and causes the pressure generating system to adjust the pressure of the flow of breathing gas responsive to detection of erratic breathing. The variable breathing algorithm seeks to develop a peak inspiratory flow trend on a 4 minute moving average, and measure the deviation above or below that trend. The system is designed to identify variable breathing and to turn over control of the pressure support system, from the auto CPAP controller to the Variable Breathing controller. Without figures, we dont know what that controller response is, but it seems if VB is detected while the pressure is steady, the VB controller will maintain that pressure, but if pressure was increasing before VB controller took control, the pressure is reduced up to 2-cm. Similarly if pressure was decreasing ...

In this paper, we describe a computer program (RESP-24) specifically devised to assess the prevalence and characteristics of breathing disorders in ambulant chronic heart failure patients during the overall 24 h period. The system works on a single channel respiratory signal (RS) recorded through a Holter-like portable device. In the pre-processing stage RESP-24 removes noise, baseline drift and motion artefacts from the RS using a non-linear filter, enhances respiratory frequency components through high-pass filtering and derives an instantaneous tidal volume (ITV) signal. The core processing is devoted to the identification and classification of the breathing pattern into periodic breathing (PB), normal breathing or non-classifiable breathing using a 60 s segmentation, and to the identification and estimation of apnea and hypopnea events. Sustained episodes of PB are detected by cross analysis of both the spectral content and time behavior of the ITV signal. User-friendly interactive ...

The goal of radiation therapy is to give as much dose as possible to the exact target location and minimizing any dose to a normal tissue. Advances of Cyber-physical control systems allow planning and provide very accurate treatments. However, the current technology does not sufficiently compensate a respiratory movement that is especially important in case of lung (area) cancer. In this paper we present a model of radiation treatment system developed to analyze a system that compensates respiratory motion. We use Uppaal, an integrated tool environment for modeling, validation and verification of real-time systems modeled as networks of timed automata, extended with data types (bounded integers, arrays, etc.).. ...

FEV1 is largely used to evaluate the bronchodilators response in COPD patients, but under conditions that do not reflect the usual ventilatory constraints. In humans, tidal spontaneous ventilation (VE) exhibits breath-by-breath variability and features mathematical complexity that is compatible with a chaotic structure. Breath-by-breath variability and nonlinear complexity have already been shown to be reliable mathematical biomarkers to describe the ventilatory flow in COPD patients during resting spontaneous breathing (Respir Physiol Neurobiol 2013; 185: 477-80). The current work aims at evaluating the resting ventilatory flow by applying a new technique called anharmonic morphological analysis of the respiratory signals (AMARS) which produces objective, accurate and specific measures of the shape of the ventilatory flow.. 24 stable COPD patients were studied (16 males; 40-86 years old; FEV1 = 71±21% pred). Resting VE was recorded for 5-10 minutes before and after a short-acting inhaled ...

Disordered breathing events may be classified as central, obstructive or a combination of central an obstructive in origin based on patient motion associated with respiratory effort. Central disordered breathing is associated with disrupted respiration with reduced respiratory effort. Obstructive disordered breathing is associated with disrupted respiration accompanied by respiratory effort. A disordered breathing classification system includes a disordered breathing detector and a respiratory effort motion sensor. Components of the disordered breathing classification system may be fully or partially implantable.

TY - JOUR. T1 - Brain-derived neurotrophic factor is required for normal development of the central respiratory rhythm in mice. AU - Balkowiec, Agnieszka. AU - Katz, David M.. PY - 1998/7/15. Y1 - 1998/7/15. N2 - 1. Molecular mechanisms underlying maturation of the central respiratory rhythm are largely unknown. Previously, we found that brain-derived neurotrophic factor (BDNF) is required for expression of normal breathing behaviour in newborn mice, raising the possibility that maturation of central respiratory output is dependent on BDNF. 2. Respiratory activity was recorded in vitro from cervical ventral roots (C1 or C4) using the isolated brainstem-spinal cord preparation from postnatal day (P) 0.5-2.0 and P4.5 wild-type mice and mice lacking functional bdnf alleles. 3. Loss of one or both bdnf alleles resulted in an approximately 50% depression of central respiratory frequency compared with wild-type controls. In addition, respiratory cycle length variability was 214% higher in bdnf null ...

PURPOSE: The short-term displacement and reproducibility of the breast or chest wall, and the internal mammary (IM), infraclavicular (ICV), and supraclavicular (SCV) nodal regions have been assessed as a function of breath-hold state using an active breathing control (ABC) device for patients receiving loco-regional breast radiation therapy. METHODS AND MATERIALS: Ten patients underwent computed tomographic scanning using an ABC device at breath-hold states of end-exhale and 20%, 40%, 60%, and 80% of vital capacity (VC). Patients underwent scanning before treatment and at one third and two thirds of the way through treatment. A regional registration was performed for each target using a rigid-body transformation with mutual information as a metric. RESULTS: Between exhale and 40% of VC, the mean displacement was 0.27/0.34, 0.24/0.31, 0.22/0.19, and 0.13/0.19 cm anterior/superior for the breast or chest wall, and IM, ICV, and SCV nodes, respectively. At 80% of VC, the mean displacement from ...

These experiments justify the following general conclusions.. By the intravenous injection of M/4 magnesium sulphate into dogs at a certain rate, a stage can be reached where the abdominal walls are completely relaxed and when section of the abdomen and stimulation of sensitive parts of the parietal peritoneum do not produce pain or elicit any reaction of the animal. At the same time spontaneous respiration may still be maintained within normal limits and the lid reflex be fair or even normal. In this stage intratracheal intubation for artificial respiration can be easily accomplished. This stage may be attained in 12 to 14 minutes when the rate of injection is about 3 cc. per minute. When this stage is once attained the rate of injection should gradually be reduced, otherwise, sooner or later, spontaneous respiration will be abolished, and by a further maintenance of the rate of injection all the skeletal muscles may become paralyzed.. When the injection of magnesium is continued for a longer ...

1. The pattern of breathing in 12 patients with severe irreversible airflow obstruction has been studied during ventilatory stimulation by rebreathing CO2. Mean maximum tidal volume response was only 1.23 +/- 0.30 litres (mean +/- SD); this represented 65% of mean measured vital capacity and 82% of mean measured inspiratory capacity. During the course of rebreathing mean total breath duration was reduced from 3.48 +/- 0.93 to 2.44 +/- 0.48 s. 2. End-expiratory thoracic gas volume (FRC) was elevated at rest in all subjects and increased significantly by a further 0.50 +/- 1.90 litres during ventilatory stimulation in 10 of the 12 subjects. The maximum increase in FRC was proportional to the degree of airflow obstruction afforded by the airways in each subject. 3. It is suggested that the increase in FRC during ventilatory stimulation is responsible for the diminished tidal volume response and is an important determinant of breathing pattern and symptomatology in patients with airflow obstruction.

The consumption of energy in prematures and newborns is primarily used to supply the heart and maintain body temperature. For newborns, the ratio of skin area to volume is lower than older children, thus it takes more oxygen to burn calories to maintain heat. Most moms recognize this, and keep newborns covered, especially from breezes. The heart pumping energy is a significant proportional user of energy in the newborn, requiring proportionally more oxygen than an older child. Finally, considering these higher uses of oxygen, and the limited lung capacity, the breathing rate has to increase in order to move more oxygen into the bloodstream per minute. Curiously, the breathing rate of prematures often exceeds 50 breaths per minute, but if you calculate the minute volume (the volume of air moved into the baby per minute), it is the same as a normal term infant ...

TY - JOUR. T1 - Control of breathing during cortical substitution of the spontaneous automatic respiratory rhythm. AU - Haouzi, Philippe. AU - Chenuel, Bruno. AU - Whipp, Brian J.. PY - 2007/11/15. Y1 - 2007/11/15. N2 - This study addresses the following question: does the ventilatory control system adjust total ventilation in accord with the regulatory demands of the physiological dead space ventilation (over(V, ̇)D) when the breathing frequency changes, and if so, how? A simple proportionality between the amplitude of the respiratory motor output (VT) and the respiratory period (TTOT) during such changes will not provide for regulation of arterial (PaC O2); the relationship requires a positive intercept of magnitude VD, i.e. VT = over(V, ̇)A TTOT + VD. We therefore determined the relationship between VT and TTOT when breathing frequency was changed in a ramp-like manner (from 6 to 20 cycles/min), in an imperceptible manner, during a paced-breathing protocol in which the subjects voluntarily ...

There are indeed numerous deaths due to synergistic combinations of sedatives and opioids. This is because sedatives obtund the primary form of respiratory drive, and opioids obtund the secondary form of respiratory drive. If both forms of respiratory drive are blocked, then respiratory drive is abolished altogether, which of course is lethal. The primary form of respiratory drive is affected by pH receptors in brain ventricles, and it determines respiratory rate and depth in conscious individuals. This form of respiratory drive is resistant to hyperventilation and depletion of CO2 tissue reserves so long as consciousnss remains present. During sleep and anesthesia, when consciousness is obtunded, the primary respiratory drive is abolished, and breathing becomes totally dependent on the secondary form of respiratory drive. The secondary form of respiratory drive is primarily determined by respiratory chemoreceptors located in extravascular tissues. These are stimulated directly by hypercarbia, ...

Data concerning pulmonary ventilation and respiratory response to elevation in alveolar pCO2 obtained from patients and subjects to whom Dromoran hydrobromide, levo-Dromoran tartrate, levallorphan tantrate or combinations of these drugs were administered intramuscularly have been presented.. In no instance was the mixture of levallorphan with levo-Dromoran in a dosage relationship of 1:1 or 1:10 capable of preventing the respiratory depression normally produced by levo-Dromoran. It is concluded that the mixture of opiates and opiate antagonists for the purpose of preserving analgesia and preventing respiratory depression is not worthwhile.. Observations are presented indicating that the measurement of respiratory rate, tidal volume, and minute volume alone may not reveal respiratory depression from narcotics. Inclusion of alveolar or arterial pCO2 values and of the respiratory response to increased concentrations of inspired carbon dioxide permit a more objective evaluation.. ...

One limitation of this study is the small number of patients. Due to the low incidence of target disease, our database included only 20 patients despite long periods. As a result, our study have no significant clip shift according to detailed analysis such as type of operation and absolute position of clip. Another shortcoming of this work was existence of conglomerate clips. Individual clip was hard to distinguish from conglomerated clips. The nearest clip from treatment center was selected in conglomerated clips. Third, the interval between imaging and treatment have the potential of respiratory change. Respiratory change have possibility of unpredictable error. Fourth, modification was aligned to clip shifts before each treatment fraction. However, one patients distal clips were shifted in the opposite direction. These clip displacement reflect postoperative change of intra-abdominal organ position as well as bowel gas change. Therefore, in this case, modification was aligned to proximal ...

It is important to avoid rapid, shallow breathing. A number of endurance athletes fall into the trap of breathing with each step or pedal stroke. This is an antiquated technique based on the belief that breathing on each footfall was important to maintain your tempo and rhythm.. The problem with this approach is that as your pace increases or you reach the upper limits of your aerobic threshold, this can actually decrease performance as your breathing becomes more rapid and shallower. This can result in hyperventilation and a lack of proper oxygen intake, delivery and absorption, which limits performance.. You can still match your breathing to your running or cycling tempo, just increase the number of footfalls or pedal strokes you take while breathing in, and do the same while exhaling. Start by inhaling for three steps and exhale for three steps again. When this becomes comfortable, increase this to five steps.. Will altitude training give you the performance boost youre after?

Apart from posture, there is also anxiety. One of the signs of anxiety and stress can also be heavy breathing. When the body begins to breathe too little and deeply instead of breathing at a natural rithm, it is impossible for one to relax. One reason may also be that the chest muscles and the abdomen get tightened and the air gets harder.. Massage plays an important role in learning the body how to relax and how to improve breathing. Respiratory problems such as allergies, sinuses, asthma or bronchitis are a group of conditions that can benefit from massage. In fact, massage can have a positive impact on respiratory function.. Many of the muscles in the front and back of the upper part of the body are breathing accessory. When these muscles are tight and shorten they can block normal breathing and interrupt effective breathing natural rithm. Massage techniques for stretching and relaxing these muscles improves breathing function and breathability. Massage leads to an opening of the chest as ...

An emergency breathing device for use of evacuation in connection with fires, chemical accidents or the like, and which comprises a heat-resisting and gas-tight protective hood (1) which is adapted to surround the head (2) of a user, and wherein there are arranged an oxygen supply unit having a reservoir (12) for the supply of oxygen to the breathing air in the hood, and a CO2 absorber (14) for purifying the breathing air. The hood (1) has double walls (3, 4) for providing a closed breathing bag (5) which is separated from the surrounding atmosphere and which is provided with a suitable positioned mouthpiece (7) for use by the user. Further, the oxygen supply unit comprises a dosing means (40) which is arranged to inject oxygen in accordance with the breathing frequency of the user.

A system and method for determining respiratory cycle-related EEG changes (RCREC) for a subject with sleep-disordered breathing are provided. The method includes receiving an EEG signal from the subject using at least one sensor, and defining at least two respiratory cycle segments within each respiratory cycle. The method further includes determining an EEG power of the EEG signal during each of the at least two respiratory cycle segments, and determining RCREC by calculating a difference between a maximum EEG segment power and a minimum EEG segment power.

Jim Morningstar, PhD, an originator of Therapeutic Breathwork, introduces breathwork with the Gender Balanced Theme, showing one of the six major breathing patterns seen in our world today. When frozen in gender confusion, this pattern has an unbalanced breathing rhythm that interferes with a more free form of expression and fulfillment of their full life potential. Jim explains the typical origins of this pattern and the breathwork goals to liberating it. For more information on Body Themes and Breathwork Training: www.transformationsusa.com.. ...

important update: Thanks to commenter DS, I discovered that my respiration-related data was strongly contaminated due to mechanical error. The belt we used is very susceptible to becoming uncalibrated, if the subject moves or breathes very deeply for example. When looking at the raw timecourse of respiration I could see that many subjects, included the one displayed…

ECHA guidance recommends that a factor of 2 be applied when doing route to route extrapolation for oral to inhalation exposure; this has been included in this case due to a lack of data or the percentage of oral absorption. Therefore a factor of 2 was applied. Allometric scaling is applied by taking account for the different breathing rates between rats and humans, as described in ECHA technical guidance the oral NOAEL in the rat mg/kg/day *1/0.38 * 6.7/10 = mg/m3 inhalation NOAEC for workers. An additional adjust was made as recommended in ECHA guidance R8.4.3. The oral exposure for the rats was 7 days a week but inhalation exposure of workers is considered to be 5 days a week. This is adjusted by dividing the NOEC by 5/7 or 0.714286. ...

Deep breathing while hiking increases your stamina and keeps muscles working better all day. Heres how to bring oxygen deep into your lungs for less fatigue and more fun.

Lydie, RE: I take it that you are of the opinion that the breathing on her own claim is a fake.. No, I do not think it is fake. Fake implies intentional fabrication. I dont think thats the case here. The only thing Ive seen that I can unequivocally call fakery was Attorney Dolans statement to the press about the MRI he displayed in his 2014 press conference. That was blatant and shameful misrepresentation, as any neurologist or radiologist can confirm. Was it intentional? Im inclined to think so, based on Dolans history.. As for the mothers claims that she is breathing, I think she is deeply, tragically mired in the confirmation bias that grips many families faced with tragic brain injury in a loved one. Ive spent a great deal of time around families trying to cope with these issues and have dealt with it in my own family. Some people veer off the rails in situations like this. I think Nailah truly believes that Jahi didnt die in 2013. She has adjusted her reality so that she can ...

Im not actually aware of any lineage that went from obligate water breathing to obligate air breathing (losing water breathing in the process), and then lost air breathing while re-evolving water breathing. I know of a few examples where some secondary water breathing adaptions appeared, but air breathing remained the primary method of obtaining oxygen.. But it should be noted that for complex macro-traits, like terrestriality, or wings, theres more than one genetic way to skin the cat, so to speak. Evolution does not have to go wholly in reverse. The second time around somewhat different genetic mechanisms might be co-opted. One could think about it as actually examples of convergent evolution happening in the same lineage, separated in time. (So for example, within the lineage that led from Urbilateria to Orca, a torpedo shaped body for swimming with fins for stabilization and direction control evolved more than once, but each time it was put together differently).. This would be different ...

Entrance to XSport.. My trainers name is Lorenzo, and the first session wasnt much of a workout. I say it wasnt much, but I still feel it, even though we didnt do all that much (which makes me a little nervous for next time).. The first session is free, and its mostly just an assessment. Height, weight, discussion about diet and when to eat. Im now adding protein shakes to my diet, and also increasing the number of times I actually eat during the day. Eating more frequently means that Ill be trying to up my metabolism, and burn more just doing normal, every day things.. I worked out on a few machines, but they were more to introduce me to the proper form, and what areas they focused on. Lorenzo kept stressing how important breathing was, and I realized it was actually something I actually had to concentrate on. It was kind of difficult to keep a regular breathing pattern, and not just hold my breath and go and go. Very weird and eye opening.. We did this ball thing with me on my back, and ...
