Velopharyngeal Insufficiency
Failure of the SOFT PALATE to reach the posterior pharyngeal wall to close the opening between the oral and nasal cavities. Incomplete velopharyngeal closure is primarily related to surgeries (ADENOIDECTOMY; CLEFT PALATE) or an incompetent PALATOPHARYNGEAL SPHINCTER. It is characterized by hypernasal speech.

Vocal Cords
A pair of cone-shaped elastic mucous membrane projecting from the laryngeal wall and forming a narrow slit between them. Each contains a thickened free edge (vocal ligament) extending from the THYROID CARTILAGE to the ARYTENOID CARTILAGE, and a VOCAL MUSCLE that shortens or relaxes the vocal cord to control sound production.

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)Air pressure, also known as atmospheric pressure, is the force per unit area exerted by the weight of air molecules above a given point in the atmosphere.
Air pressure, also known as atmospheric pressure, is the force exerted by the weight of air in the atmosphere on a surface. It is measured in units such as pounds per square inch (psi), hectopascals (hPa), or inches of mercury (inHg). The standard atmospheric pressure at sea level is defined as 101,325 Pa (14.7 psi/1013 hPa/29.92 inHg). Changes in air pressure can be used to predict weather patterns and are an important factor in the study of aerodynamics and respiratory physiology.
Velopharyngeal Insufficiency (VPI) is a medical condition where the velopharyngeal valve, responsible for separating the nasal and oral cavities during speech, does not function properly, leading to air leakage into the nose and articulation problems.
Velopharyngeal Insufficiency (VPI) is a medical condition that affects the proper functioning of the velopharyngeal valve, which is responsible for closing off the nasal cavity from the mouth during speech. This valve is made up of the soft palate (the back part of the roof of the mouth), the pharynx (the back of the throat), and the muscles that control their movement.
In VPI, the velopharyngeal valve does not close completely or properly during speech, causing air to escape through the nose and resulting in hypernasality, nasal emission, and/or articulation errors. This can lead to difficulties with speech clarity and understanding, as well as social and emotional challenges.
VPI can be present from birth (congenital) or acquired later in life due to factors such as cleft palate, neurological disorders, trauma, or surgery. Treatment for VPI may include speech therapy, surgical intervention, or a combination of both.
In a medical context, 'Air' refers to the mixture of gases (approximately 78% nitrogen, 21% oxygen, and 1% other gases) that we breathe in and out of our lungs, essential for respiration and life sustenance.
In medical terms, 'air' is defined as the mixture of gases that make up the Earth's atmosphere. It primarily consists of nitrogen (78%), oxygen (21%), and small amounts of other gases such as argon, carbon dioxide, and trace amounts of neon, helium, and methane.
Air is essential for human life, as it provides the oxygen that our bodies need to produce energy through respiration. We inhale air into our lungs, where oxygen is absorbed into the bloodstream and transported to cells throughout the body. At the same time, carbon dioxide, a waste product of cellular metabolism, is exhaled out of the body through the lungs and back into the atmosphere.
In addition to its role in respiration, air also plays a critical role in regulating the Earth's climate and weather patterns, as well as serving as a medium for sound waves and other forms of energy transfer.
'Pressure' in a medical context is defined as the force applied per unit area, often quantified in millimeters of mercury (mmHg) or pounds per square inch (psi), and crucial in understanding and measuring various bodily functions such as blood pressure and intracranial pressure.
In medical terms, pressure is defined as the force applied per unit area on an object or body surface. It is often measured in millimeters of mercury (mmHg) in clinical settings. For example, blood pressure is the force exerted by circulating blood on the walls of the arteries and is recorded as two numbers: systolic pressure (when the heart beats and pushes blood out) and diastolic pressure (when the heart rests between beats).
Pressure can also refer to the pressure exerted on a wound or incision to help control bleeding, or the pressure inside the skull or spinal canal. High or low pressure in different body systems can indicate various medical conditions and require appropriate treatment.
"Weather," in a medical context, is not defined as a specific term; however, it often refers to the atmospheric conditions including temperature, humidity, air pressure, wind, and precipitation that may potentially influence an individual's health or various environmental factors affecting patient care, such as outdoor air quality.
I'm sorry for any confusion, but "weather" is not a medical term. Weather refers to the state of the atmosphere at a particular place and time, including factors such as temperature, humidity, cloudiness, precipitation, and wind. If you have any questions about medical terms or concepts, I would be happy to try to help answer those for you!
Humidity, in a medical context, refers to the amount of water vapor present in the air, which can influence comfort, temperature perception, and potential for microbial growth or respiratory issues in indoor environments.
Humidity, in a medical context, is not typically defined on its own but is related to environmental conditions that can affect health. Humidity refers to the amount of water vapor present in the air. It is often discussed in terms of absolute humidity (the mass of water per unit volume of air) or relative humidity (the ratio of the current absolute humidity to the maximum possible absolute humidity, expressed as a percentage). High humidity can contribute to feelings of discomfort, difficulty sleeping, and exacerbation of respiratory conditions such as asthma.
Speech production measurement is the quantitative analysis and assessment of various spatiotemporal, acoustic, and articulatory aspects involved in the planning, execution, and control of spoken language to diagnose and monitor speech disorders or improve communication effectiveness.
Speech production measurement is the quantitative analysis and assessment of various parameters and characteristics of spoken language, such as speech rate, intensity, duration, pitch, and articulation. These measurements can be used to diagnose and monitor speech disorders, evaluate the effectiveness of treatment, and conduct research in fields such as linguistics, psychology, and communication disorders. Speech production measurement tools may include specialized software, hardware, and techniques for recording, analyzing, and visualizing speech data.
The vocal cords, also known as the vocal folds, are specialized bands of tissue located within the larynx that vibrate to produce sound during phonation, a key process in speech and singing.
Vocal cords, also known as vocal folds, are specialized bands of muscle, membrane, and connective tissue located within the larynx (voice box). They are essential for speech, singing, and other sounds produced by the human voice. The vocal cords vibrate when air from the lungs is passed through them, creating sound waves that vary in pitch and volume based on the tension, length, and mass of the vocal cords. These sound waves are then further modified by the resonance chambers of the throat, nose, and mouth to produce speech and other vocalizations.
"Blood pressure is the force exerted by circulating blood on the walls of the blood vessels, measured in terms of systolic pressure (when the heart beats) and diastolic pressure (when the heart rests)."
Blood pressure is the force exerted by circulating blood on the walls of the blood vessels. It is measured in millimeters of mercury (mmHg) and is given as two figures:
1. Systolic pressure: This is the pressure when the heart pushes blood out into the arteries.
2. Diastolic pressure: This is the pressure when the heart rests between beats, allowing it to fill with blood.
Normal blood pressure for adults is typically around 120/80 mmHg, although this can vary slightly depending on age, sex, and other factors. High blood pressure (hypertension) is generally considered to be a reading of 130/80 mmHg or higher, while low blood pressure (hypotension) is usually defined as a reading below 90/60 mmHg. It's important to note that blood pressure can fluctuate throughout the day and may be affected by factors such as stress, physical activity, and medication use.
'Hydrostatic pressure' in a medical context refers to the force exerted by a column of fluid on a specific point within or adjacent to that fluid, which is determined by the height of the fluid column, its density, and the acceleration due to gravity.
Hydrostatic pressure is the pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. In medical terms, hydrostatic pressure is often discussed in relation to body fluids and tissues. For example, the hydrostatic pressure in the capillaries (tiny blood vessels) is the force that drives the fluid out of the blood vessels and into the surrounding tissues. This helps to maintain the balance of fluids in the body. Additionally, abnormal increases in hydrostatic pressure can contribute to the development of edema (swelling) in the tissues.
'Air pollutants' are substances or forms of energy present in the air that can have adverse effects on human health and/or the environment.
Air pollutants are substances or mixtures of substances present in the air that can have negative effects on human health, the environment, and climate. These pollutants can come from a variety of sources, including industrial processes, transportation, residential heating and cooking, agricultural activities, and natural events. Some common examples of air pollutants include particulate matter, nitrogen dioxide, sulfur dioxide, ozone, carbon monoxide, and volatile organic compounds (VOCs).
Air pollutants can cause a range of health effects, from respiratory irritation and coughing to more serious conditions such as bronchitis, asthma, and cancer. They can also contribute to climate change by reacting with other chemicals in the atmosphere to form harmful ground-level ozone and by directly absorbing or scattering sunlight, which can affect temperature and precipitation patterns.
Air quality standards and regulations have been established to limit the amount of air pollutants that can be released into the environment, and efforts are ongoing to reduce emissions and improve air quality worldwide.
'Air pollution' is the presence or introduction into the atmosphere of substances or combinations of substances, whether gases, particles, or biological molecules, which cause harm or discomfort to humans or other living organisms, or damage to the environment.
Air pollution is defined as the contamination of air due to the presence of substances or harmful elements that exceed the acceptable limits. These pollutants can be in the form of solid particles, liquid droplets, gases, or a combination of these. They can be released from various sources, including industrial processes, vehicle emissions, burning of fossil fuels, and natural events like volcanic eruptions.
Exposure to air pollution can have significant impacts on human health, contributing to respiratory diseases, cardiovascular issues, and even premature death. It can also harm the environment, damaging crops, forests, and wildlife populations. Stringent regulations and measures are necessary to control and reduce air pollution levels, thereby protecting public health and the environment.
'Blood Pressure Determination' is the process of measuring and evaluating the force applied by blood on the walls of the arteries, during both heartbeats and rest, to assess cardiovascular health and identify any underlying conditions or abnormalities.
Blood pressure determination is the medical procedure to measure and assess the force or pressure exerted by the blood on the walls of the arteries during a heartbeat cycle. It is typically measured in millimeters of mercury (mmHg) and is expressed as two numbers: systolic pressure (the higher number, representing the pressure when the heart beats and pushes blood out into the arteries) and diastolic pressure (the lower number, representing the pressure when the heart rests between beats). A normal blood pressure reading is typically around 120/80 mmHg. High blood pressure (hypertension) is defined as a consistently elevated blood pressure of 130/80 mmHg or higher, while low blood pressure (hypotension) is defined as a consistently low blood pressure below 90/60 mmHg. Blood pressure determination is an important vital sign and helps to evaluate overall cardiovascular health and identify potential health risks.
Air embolism is a medical condition characterized by the obstruction of blood vessels by air bubbles that enter the circulation, typically occurring due to trauma, surgical procedures, or decompression sickness.
An air embolism is a medical condition that occurs when one or more air bubbles enter the bloodstream and block or obstruct blood vessels. This can lead to various symptoms depending on the severity and location of the obstruction, including shortness of breath, chest pain, confusion, stroke, or even death.
Air embolisms can occur in a variety of ways, such as during certain medical procedures (e.g., when air is accidentally introduced into a vein or artery), trauma to the lungs or blood vessels, scuba diving, or mountain climbing. Treatment typically involves administering oxygen and supportive care, as well as removing the source of the air bubbles if possible. In severe cases, hyperbaric oxygen therapy may be used to help reduce the size of the air bubbles and improve outcomes.
