Breathing responses to small inspiratory threshold loads in humans. (1/314)

To investiage the effect of inspiratory threshold load (ITL) on breathing, all previous work studied loads that were much greater than would be encountered under pathophysiological conditions. We hypothesized that mild ITL from 2.5 to 20 cmH2O is sufficient to modify control and sensation of breathing. The study was performed in healthy subjects. The results demonstrated that with mild ITL 1) inspiratory difficulty sensation could be perceived at an ITL of 2.5 cmH2O; 2) tidal volume increased without change in breathing frequency, resulting in hyperpnea; and 3) although additional time was required for inspiratory pressure to attain the threshold before inspiratory flow was initiated, the total inspiratory muscle contraction time remained constant. This resulted in shortening of the available time for inspiratory flow, so that the tidal volume was maintained or increased by significant increase in mean inspiratory flow. On the basis of computer simulation, we conclude that the mild ITL is sufficient to increase breathing sensation and alter breathing control, presumably aiming at maintaining a certain level of ventilation but minimizing the energy consumption of the inspiratory muscles.  (+info)

Compliance and stability of the bronchial wall in a model of allergen-induced lung inflammation. (2/314)

Airway wall remodeling in response to inflammation might alter load on airway smooth muscle and/or change airway wall stability. We therefore determined airway wall compliance and closing pressures in an animal model. Weanling pigs were sensitized to ovalbumin (OVA; ip and sc, n = 6) and were subsequently challenged three times with OVA aerosol. Control pigs received 0.9% NaCl (n = 4) in place of OVA aerosol. Bronchoconstriction in vivo was assessed from lung resistance and dynamic compliance. Semistatic airway compliance was recorded ex vivo in isolated segments of bronchus, after the final OVA aerosol or 0.9% NaCl challenge. Internally or externally applied pressure needed to close bronchial segments was determined in the absence or presence of carbachol (1 microM). Sensitized pig lungs exhibited immediate bronchoconstriction to OVA aerosol and also peribronchial accumulations of monocytes and granulocytes. Compliance was reduced in sensitized bronchi in vitro (P < 0.01), and closing pressures were increased (P < 0.05). In the presence of carbachol, closing pressures of control and sensitized bronchi were not different. We conclude that sensitization and/or inflammation increases airway load and airway stability.  (+info)

Barometric pressures on Mt. Everest: new data and physiological significance. (3/314)

Barometric pressures (PB) near the summit of Mt. Everest (altitude 8, 848 m) are of great physiological interest because the partial pressure of oxygen is very near the limit for human survival. Until recently, the only direct measurement on the summit was 253 Torr, which was obtained in October 1981, but, despite being only one data point, this value has been used by several investigators. Recently, two new studies were carried out. In May 1997, another direct measurement on the summit was within approximately 1 Torr of 253 Torr, and meteorologic data recorded at the same time from weather balloons also agreed closely. In the summer of 1998, over 2,000 measurements were transmitted from a barometer placed on the South Col (altitude 7,986 m). The mean PB values during May, June, July, and August were 284, 285, 286, and 287 Torr, respectively, and there was close agreement with the PB-altitude (h) relationship determined from the 1981 data. The PB values are well predicted from the equation PB = exp (6.63268 - 0.1112 h - 0.00149 h2), where h is in kilometers. The conclusion is that on days when the mountain is usually climbed, during May and October, the summit pressure is 251-253 Torr.  (+info)

Influence of gas density on simulated snoring. (4/314)

According to a recent theoretical model, snoring is related to instability of the upper airway (UA). Factors promoting UA instability include increased gas density. The aim of this study was to test the influence of gas density on simulated snoring production and supraglottic resistance. Supraglottic pressure and flow rate (V') were measured in 10 healthy seated subjects during simulated snoring. Subjects breathed three different gas mixtures: Helium-oxygen, He 79%-O2 21% (He-O2); air; and sulphur hexafluoride-oxygen, F6S 79%-O2 21% (F6S-O2) administered in a random order. Supraglottic resistance (Rsg) was measured on its linear range during quiet breathing and V' was measured at the onset and middle of snoring. Linear Rsg increased and V' conversely decreased with gas density. These data are in agreement with predictions of a mathematical model of the upper airway showing that snoring occurs at lower flow rates when gas density is increased.  (+info)

Acute mountain sickness is not related to cerebral blood flow: a decompression chamber study. (5/314)

To evaluate the pathogenetic role of cerebral blood flow (CBF) changes occurring before and during the development of acute mountain sickness (AMS), peak mean middle cerebral artery flow velocities () were assessed by transcranial Doppler sonography in 10 subjects at 490-m altitude, and during three 12-min periods immediately (SA1), 3 (SA2), and 6 (SA3) h after decompression to a simulated altitude of 4,559 m. AMS cerebral scores increased from 0. 16 +/- 0.14 at baseline to 0.44 +/- 0.31 at SA1, 1.11 +/- 0.88 at SA2 (P < 0.05), and 1.43 +/- 1.03 at SA3 (P < 0.01); correspondingly, three, seven, and eight subjects had AMS. Absolute and relative at simulated altitude, expressed as percentages of low-altitude values (%), did not correlate with AMS cerebral scores. Average % remained unchanged, because % increased in three and remained unchanged or decreased in seven subjects at SA2 and SA3. These results suggest that CBF is not important in the pathogenesis of AMS and shows substantial interindividual differences during the first hours at simulated altitude.  (+info)

Preliminary evaluation of a new prototype laryngeal mask in children. (6/314)

We have assessed a prototype laryngeal mask airway (pLMA) in 50 anaesthetized children for ease of insertion, oropharyngeal leak pressures, gastric insufflation and fibreoptic position. The pLMA has a second smaller mask, which rests against the upper oesophageal sphincter, and a second cuff to increase the seal pressure of the glottic mask. All insertions were graded as easy and an effective airway was achieved in all patients. Oropharyngeal leak pressure was > 40 cm H2O in 49 of 50 patients. Gastric insufflation was not detected by epigastric auscultation. In 46 of 50 patients, the vocal cords were seen via a fibreoptic laryngoscope. One patient regurgitated clear fluid, but aspiration did not occur. On removal, blood staining was detected in three of 50 children. We conclude that the pLMA was easy to insert, facilitated high airway pressure ventilation and may provide some protection against gastric insufflation.  (+info)

Small tidal volume ventilation using a zero deadspace tracheal tube. (7/314)

The zero deadspace tracheal tube (ZEDS-TT) is a double-lumen endobronchial tube with a truncated bronchial limb. Functionally it is unrelated to the familiar endobronchial tube used in lung isolation surgery. It is placed in the same position as a regular tracheal tube and, by means of special connectors, one limb is used for inspiration and the other for expiration, thereby greatly reducing anatomical and apparatus deadspace. In this study, we have compared respiratory and ventilatory effects of reduction of tidal volume (VT) via a single-lumen tracheal tube and the ZEDS-TT during controlled ventilation with a Siemens Elema 900C Servo ventilator. Eleven consenting adult patients (ASA I and II) undergoing elective peripheral surgery were studied. Starting at a VT value of 10 ml kg-1, data were recorded for each tube type. VT was reduced by 2.5 ml kg-1 every 10 min and stabilized data recorded. Minute volume was kept constant by increasing ventilatory frequency at each reduction in VT. We found that the ZEDS-TT produced a significant reduction in PaCO2 and airway pressure for any VT used, while maintaining oxygenation.  (+info)

Comparison of four methods for assessing airway sealing pressure with the laryngeal mask airway in adult patients. (8/314)

We have compared four tests for assessing airway sealing pressure with the laryngeal mask airway (LMA) to test the hypothesis that airway sealing pressure and inter-observer reliability differ between tests. We studied 80 paralysed, anaesthetized adult patients. Four different airway sealing pressure tests were performed in random order on each patient by two observers blinded to each other's measurements: test 1 involved detection of an audible noise; test 2 was detection of end-tidal carbon dioxide in the oral cavity; test 3 was observation of the aneroid manometer dial as the pressure increased to note the airway pressure at which the dial reached stability; and test 4 was detection of an audible noise by neck auscultation. Mean airway sealing pressure ranged from 19.5 to 21.3 cm H2O and intra-class correlation coefficient was 0.95-0.99. Inter-observer reliability of all tests was classed as excellent. The manometric stability test had a higher mean airway sealing pressure (P < 0.0001) and better inter-observer reliability (P < 0.0001) compared with the three other tests. We conclude that for clinical purposes all four tests are excellent, but that the manometric stability test may be more appropriate for researchers comparing airway sealing pressures.  (+info)

AU - Sircar, Shivaji. PY - 2015. Y1 - 2015. N2 - The effects of feed air pressure on the steady-state performance of a medical oxygen concentrator (MOC) were experimentally evaluated using a novel design of a MOC unit which produced a continuous stream of ∼90% O2 employing a rapid pressure swing adsorption (RPSA) process scheme. Dry, CO2 free air containing ∼1% Ar at different feed gas pressures was used in the tests in conjunction with a commercial sample of LiLSX zeolite as the N2 selective adsorbent in the process. The bed size factor (BSF) can be systematically reduced by increasing the feed air pressure for any given total cycle time. The effect of feed air pressure on the oxygen recovery (R) is, however, more complex; it increases with increasing feed pressure only at longer cycle times while the ...

0031] Referring to FIG. 6, in virtue of the ball-specific recommended pressure dial 60, a user reading the reading pointed by the air-pressure indicator 40 can at the same time be informed of whether the air pressure inside the ball 90 is appropriate for the particular ball. If the measured air pressure inside the ball 90 is lower than the recommended range for that ball, inflation can be conducted again to raise the air pressure inside the ball 90. If the air pressure inside the ball 90 is greater than the recommended range, the pressure-resealing valve 30 can be operated to allow the air inside the ball 90 to communicate with the external, ambient atmosphere through the probe 20, thereby releasing some air to reduce the air pressure inside the ball 90. Then, when the air-pressure indicator 40 points the air pressure as one applicable to the ball, the pressure-resealing valve 30 can be closed, so the adjustment of air pressure inside the ball 90 is completed ...
The Air Pressure Homemade operates on the principle of air-pressure. During the first stage of operation, the rigid chamber is filled with air at room temperature and pressure. An inlet and outlet exist, and the outlet is closed. During the second stage of operation, water is drawn into the pump through the first check valve. During the third stage of operation, the pump is retracted, forcing water through the second check valve and into the rigid chamber. The air in the chamber will rise above the water as it is much lighter, and this orientation will be preserved normal to the direction of gravity (it is for this reason that most APH designs do not work when inverted. As the volume of water increases, the air pressure above the water increases because the air is much more easily compressed than the water. Eventually a maximum pressure will be reached. This pressure will be dictated either by the strength of the input force or by the tensile strength of the chamber material, whichever is lower. ...

As with so many amazing science demonstrations, projects, and experiments, the Homemade Lung works because of air pressure. When the bottle is sealed off by the balloon on one end and the cap, straw, and balloon at the other, you create a container that is nearly airtight. Air cannot go in or out.. When you pull the balloon, you are increasing the volume of the container. However, the volume of air inside the container remains the same. This creates an area of low air pressure inside of the bottle, while the air pressure outside the bottle remains the same. The higher air pressure from outside the bottle forces itself into the only opening the bottle has, the straw. Outside air rushes to fill the straw and the connected balloon until the air pressure has balanced. Releasing the ballon takes the container back to its original air pressure and the balloon deflates as air rushes out of the straw.. ...

This study examines experimentally and for the first time the effect of reduced air pressure on dynamic wetting. The purpose is to assess the role of air viscosity on dynamic wetting failure which hitherto has been speculated on but not measured. In this paper we used dip coating as the model experimental flow and report data on air entrainment velocity Vae we measured with a series of silicone oils in a range of viscosities in a vacuum chamber where the pressure can be reduced from atmospheric down to a few mbar when the mean molecular free path of air is large and air ceases to have a viscosity. To complement earlier work, we carried out the experiments with a range of substrates of varying roughness. The substrates were chosen so that for each one, their two sides differ in roughness. This enables simultaneous comparative observation of their wetting performance and reduces the experimental error in assessing the role of roughness. The data presented here capture the effects of viscosity, ...

Air pressure at Londons Heathrow Airport rose to a record high on Monday (20 January), surpassing all daily readings in the capital since records began in 1692.. The reading of 1049.6 milibars (mbar), recorded at midnight on 19/20 January, was 2.3 mbar higher than the previous Heathrow record of 1964. The previous high for London as a whole was 1049.1 mbar, recorded at Kew Observatory at 11am on 18 January 1882.. High pressure typically brings dry weather and clear skies, with large changes in temperature from day to night.. A University of Reading expert has attributed the unusual conditions to an area of intense low pressure that rapidly developed off the east coast of the US a few days earlier, causing a storm that dumped around 75cm of snow on Newfoundland.. Stephen Burt, Visiting Fellow in Meteorology at the University of Reading, said: Exceeding a previous extreme by such a large value is extremely unusual. This is also the first time for over 60 years that 1050 mbar has been attained ...

Barotrauma is explained by Health24 as a condition where there is inflammation of the middle ear, causing severe pain. When the air pressure in the airplane cabin changes rapidly during takeoff and landing it causes painful pressure in your ear. It hurts because your ears cannot adjust quickly enough to the change in air pressure, trapping air and fluid in the middle ear. Under normal circumstances the air pressure in your inner ear and the air pressure outside are equal. However, when external pressure changes very quickly, the inner ear experiences extreme pressure because it cannot adjust at the same speed. Apart from causing severe pain, the air and fluid trapped inside the middle ear can occasionally cause the middle ear to rupture ...

  • How temperature effects the height of pressure. (
  • This change in pressure is caused by changes in air density, and air density is related to temperature. (
  • Humidity is measured by a psychrometer, which indicates the amount of water in the air at any one temperature. (
  • And over the years, outfits such as HP, Opengate Data Systems, and SynapSense have sold various tools that use temperature and pressure sensors to help drive hardware inside the data center. (
  • At a given pressure difference, a server can only handle a certain workload without exceeding a particular temperature threshold, and Facebook's system attempts to keep the servers as close to this threshold as possible. (
  • How do air pressure and temperature change with altitude? (
  • As altitude increases, temperature increases by 12.5oC every 1km upwards, and pressure rapidly decreases. (
  • If the Earth's atmosphere had a uniform density throughout and if air temperature were equal to the average value at sea level (15 C, 59 F), the top of the atmosphere would be at only 8 km (5 mile) altitude. (
  • i) At constant pressure, the absolute temperature and density of an ideal gas are inversely proportional. (
  • T a (1/ r ) ii) At constant density, the pressure and absolute temperature of an ideal gas are directly proportional. (
  • the temperature of dry air having same pressure and density as moist air. (
  • Temperature is a measure of the average kinetic energy of individual air molecules. (
  • Humid air is lighter (less dense) exerting less pressure than dry air at the same temperature. (
  • At this altitude, a total loss of cabin pressure would cause the temperature inside the plane to drop dramatically, to between -40°C and -60°C, and the air would rapidly become unbreathable as oxygen levels suddenly dropped. (
  • CO2 will condense at ocean pressures, I know that I don't however know the math to determine gas condensation temperature pressure relations for the other ones. (
  • if you went to the arctic you'd get the same pressures but lower temperature which might help but not so much. (
  • High pressure typically brings dry weather and clear skies, with large changes in temperature from day to night. (
  • However, since the density of mercury is a function of temperature, the air pressure measurements made with a mercury barometer are also a function of temperature. (
  • However, in general, due to the effects of temperature, there will be some difference between a barometer reading and the actual air pressure. (
  • Due to the uncertainty of the temperature dependence, barometric pressure readings are not generally appropriate for use in accurately calculating Density Altitude and/or Engine Horsepower. (
  • In general, conversion from actual barometric pressure to sea-level barometric pressure includes certain effects of temperature. (
  • Variations in atmospheric humidity, temperature, and barometric pressure substantially affect almost all engine mass and volume exhaust emissions. (
  • Therefore, accurate emission testing on some engines can only be accomplished by controlling inlet air temperature and by testing on days of similar barometric pressure. (
  • A circuit is provided for simultaneously measuring intake temperature using a single bridge type pressure sensor in order to calculate air mass flow rate. (
  • They're custom designed to deliver air directly to high-temperature components with less noise and turbulence than ordinary fans. (
  • The exact pressure needed for play is affected by the playing surface, environmental temperature and external air pressure. (
  • Science fair project examining barometric pressure, and how it can be used to predict the weather. (
  • Unfortunately, there are a variety of slightly different methods used to convert from the actual barometric pressure to the sea-level corrected pressure. (
  • And, due to the various sensors and algorithms which are employed in calculating the sea-level barometric pressure, the accuracy of any conversion from the sea-level corrected barometric pressure to absolute pressure is unpredictable (unless the specific type of sensor and the specific algorithm used to make the sea-level correction are known). (
  • So, while the average altitude of the 500 millibar level is around 18,000 feet (5,600 meters) the actual elevation will be higher in warm air than in cold air. (
  • Air pressure changes with altitude. (
  • QNH will get the altimeter to show elevation at the airfield and altitude above the air field. (
  • Does air pressure increase as altitude increases? (
  • What does air pressure do when altitude increases? (
  • How does air pressure change when altitude increases? (
  • How does the air pressure change as the altitude increases? (
  • Air pressure decreases as altitude increases. (
  • How is air pressure related to altitude? (
  • What effect on air pressure with altitude explain briefly? (
  • Is it true or false that Air pressure increases as Altitude increases? (
  • What happens to the altitude when the air pressure increases? (
  • Air pressure increase with lower altitude. (
  • Atmospheric pressure is due to air mass loading down to surface, high altitude had smaller amount of air mass on top. (
  • How does air pressure changes altitude increases? (
  • As your altitude decreases, there is more air on top of you, therefore, the air pressure increases. (
  • What happens to air pressure as the altitude of the layers of th e atmosphere increase? (
  • Air pressure change in each layer of the earth as altitude increases due to variation in the density of air. (
  • At high altitude, air pressure is low due to less density of air up there. (
  • False, air pressure goes down as altitude increases. (
  • So when you increase altitude you are reaching the top of the fluid therefore decreasing pressure. (
  • Increased altitude means decreased air pressure. (
  • Is it true that air pressure decreases as altitude decreases? (
  • No. Air pressure decreases with altitude. (
  • Is it true that as altitude increases the density of the air increases? (
  • What happens to atmospheric pressure as altitude increase? (
  • Simply because of the fact that as altitude increases, the less air there is on top of you, and the lower the pressure would be. (
  • What general statement can be made about the relationship between air pressure and altitude? (
  • How does increasing altitude affect air pressure and density? (
  • As the altitude increases, the pressure and the density of the atmosphere decrease. (
  • But as the altitude increases, air gets thinner in other words the molecules in air are farther than the one close to earth's surface. (
  • This causes the atmospheric pressure to decrease as we increase in altitude. (
  • What happens to the pressure as altitude increases in the troposphere? (
  • The number of air molecules per unit volume decreases with altitude rapidly such that air density at 16 km (~10 mile) altitude is only about 10% of its average sea level value. (
  • The decrease of air density with altitude is accompanied by a decline in air pressure. (
  • Florin Perier (French, 1658) was the first who observed the drop of air pressure with altitude. (
  • Because of the compressibility of air, air pressure and air density decrease rapidly with altitude in the lower troposphere and become more gradual aloft. (
  • In terms of air pressure, at an altitude of only 32 km, air pressure is less than 1% of its average sea level value. (
  • Crash investigators are continuing their probe into the Greek passenger jet disaster just north of Athens on Sunday, with the early evidence pointing towards a sudden and catastrophic loss of cabin pressure at high altitude. (
  • Pressure inside a 737 is maintained at the equivalent of 3000 metres (10,000 feet) altitude by a mechanical system of valves. (
  • At that altitude, the air is breathable and much warmer. (
  • Kieran Daly, at Air Transport Intelligence magazine says the pilots would have had just seconds to react to a rapid loss of pressure at such high altitude. (
  • The feeling of pain or popping in your ears during a flight is a common reaction to altitude-related changes in cabin air pressure. (
  • Here are some guidelines to aid in choosing a suitable measurement of absolute air pressure for accurate calculation of Density Altitude and/or Engine Horsepower. (
  • The absolute air pressure may be directly read in the Kollsman window of a properly calibrated aircraft altimeter by turning the adjustment knob until the altimeter indicates an altitude of zero (if the altimeter has sufficient adjustment range to do so). (
  • Another method to obtain Absolute Pressure is to set the altimeter to 29.92, and then convert the resulting Pressure Altitude reading to the corresponding Absolute Pressure. (
  • For the convenience of pilots, some of my on-line Density Altitude calculators utilize Altimeter Setting and Elevation rather than requiring the Absolute Pressure. (
  • But altitude obviously has a very strong effect on the pressure, so what's going on? (
  • A pressure regulator is a valve that controls air flow from a compressor. (
  • Noises from the regulator indicate an air leak or obstruction. (
  • Find the nut for the fitting at the bottom of the pressure regulator. (
  • Disconnect the pressure regulator from the air compressor. (
  • Insert the pressure regulator back into the air compressor. (
  • Check to see if the noise from the pressure regulator is gone by using the air compressor as you normally would. (
  • Remove the adjustment knob at the top of the pressure regulator by loosening the nut under the knob with the wrench. (
  • Remove the knob and top section of the pressure regulator. (
  • Lubricate the rubber washer on the regulator assembly with the air tool oil. (
  • Replace the pressure regulator with a new part if the noise does not go away. (
  • An official with India's national aviation regulator told the Press Trust of India the crew "forgot to select (the) bleed switch" to maintain the aircraft's cabin pressure. (
  • However, when we sum the total forces from the large number of molecules that strike a surface each moment, then the total observed pressure can be considerable. (
  • First, simply adding molecules to any particular container will increase the pressure. (
  • A larger number of molecules in any particular container will increase the number of collisions with the container's boundary which is observed as an increase in pressure. (
  • By adding air, the number of molecules increase as well a the total number of the collisions with the tire's inner boundary. (
  • Adding heat to any particular container can transfer energy to air molecules. (
  • The molecules therefore move with increased velocity striking the container's boundary with greater force and is observed as an increase in pressure. (
  • Since molecules move in all directions, they can even exert air pressure upwards as they smash into object from underneath. (
  • Back on Earth, as elevation increases, the number of molecules decreases and the density of air therefore is less, meaning a decrease in air pressure. (
  • In fact, while the atmosphere extends more than 15 miles (24 km) up, one half of the air molecules in the atmosphere are contained within the first 18,000 feet (5.6 km). (
  • Warm air is less dense than cooler air because the gas molecules in warm air have a greater velocity and are farther apart than in cooler air. (
  • When you move to a higher place, say a tall mountain, air pressure decreases because there are fewer air molecules as you move higher in the sky. (
  • There are fewer gas molecules in a given volume as we go up in elevation, therefore, making the air pressure less and less. (
  • From 70 miles above Earth to the surface of Earth there are air molecules that occupy volume in the air. (
  • These air molecules create more and more weight on the air molecules under each one, pushing them closer together causing a significant amount of air pressure at Earth's surface. (
  • The air molecules stacked on top of each other react the same way. (
  • The air molecules at the top of the atmosphere (70 miles up) do not have much weight on them, resulting in very little air pressure. (
  • The air molecules at Earth's surface (the bottom of the pile) are being pushed together by all the weight of the air molecules from top to bottom resulting in 15 pounds of pressure per square inch. (
  • Depending on how many air molecules there are in a given space depends on how much air pressure there will be in that space. (
  • However, the air pressure above Earth's surface gradually gets less and less the higher the air is because there are fewer air molecules packed together in the same amount of space. (
  • The reason it rises is the air molecules spread out causing fewer air particles existing in that given area. (
  • Mass of air molecules per unit volume of air. (
  • Air density has its maximum at the Earth's surface where air molecules are most closely spaced. (
  • Other manufacturers offer gauges that screw on the tire stem with a red flag or button that pops out when the pressure drops below a certain level. (
  • With these gauges, the valve on the tire stem is open continuously, which assures some loss of air pressure. (
  • Since proper tire inflation is critical to getting the best fuel mileage, every car maker should include one of these nice pressure gauges with each new car. (
