Act of listening for sounds within the heart.
Instruments intended to detect and study sound produced by the heart, lungs, or other parts of the body. (from UMDNS, 1999)
Heart sounds caused by vibrations resulting from the flow of blood through the heart. Heart murmurs can be examined by HEART AUSCULTATION, and analyzed by their intensity (6 grades), duration, timing (systolic, diastolic, or continuous), location, transmission, and quality (musical, vibratory, blowing, etc).
The sounds heard over the cardiac region produced by the functioning of the heart. There are four distinct sounds: the first occurs at the beginning of SYSTOLE and is heard as a "lubb" sound; the second is produced by the closing of the AORTIC VALVE and PULMONARY VALVE and is heard as a "dupp" sound; the third is produced by vibrations of the ventricular walls when suddenly distended by the rush of blood from the HEART ATRIA; and the fourth is produced by atrial contraction and ventricular filling.

Bruits, ophthalmodynamometry and rectilinear scanning on transient ischemic attacks. (1/162)

One hundred seventeen patients with clinical signs and symptoms of transient ischemic attacks (TIAs) were evaluated. All underwent clinical evaluation for bruit, ophthalmodynamometry, rapid sequence scintiphotography with rectilinear scanning and four-vessel cerebral angiography. The results of these tests were compared for reliability in predicting location of lesions causing transient ischemic attacks. Angiography remains the most accurate procedure in evaluating extracranial vascular lesions. When determination of bruits, ophthalmodynamometry and brain scanning are done together, accuracy is greater than when any one of the procedures is done alone.  (+info)

Comparison of four methods for assessing airway sealing pressure with the laryngeal mask airway in adult patients. (2/162)

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)

Effect of positioning on recorded lung sound intensities in subjects without pulmonary dysfunction. (3/162)

BACKGROUND AND PURPOSE: Physical therapists often use positioning to assist in the reexpansion of collapsed lung segments. An increase in lung sound intensity on auscultation is considered indicative of lung expansion. This study was designed to examine whether clinical interpretation of auscultatory findings is warranted. SUBJECTS: The subjects (5 male, 6 female) were young physical therapist students without pulmonary dysfunction (mean age=20.4 years, mean height=166.3 cm, mean weight=57.5 kg). Subjects with lung disease were excluded because pulmonary pathology is difficult to standardize. METHODS: Lung sounds electronically recorded over the posterior chest wall of subjects in sitting and side-lying positions were compared. Measures included peak intensity, frequency at maximum power, and median frequency. RESULTS: In the sitting position, inspiratory sounds recorded over the left posterior chest wall were louder than those recorded on the right side. In the side-lying positions, the sound intensity recorded from the dependent chest wall was louder than that recorded from the nondependent chest wall. In side-lying positions, the upper hemithorax is "nondependent," and the side in contact with the bed is "dependent." Sound intensities recorded over both posterior chest walls in the sitting position were louder than those recorded over the same lung area in the nondependent side-lying position. There was no difference in the sound intensity recorded between the sitting and dependent side-lying postures. CONCLUSION AND DISCUSSION: When comparative auscultation of the chest wall is used by physical therapists to assess the adequacy of pulmonary ventilation, patient posture and regional differences in breath sound intensity can influence clinical interpretation.  (+info)

Heart murmurs in pediatric patients: when do you refer? (4/162)

Many normal children have heart murmurs, but most children do not have heart disease. An appropriate history and a properly conducted physical examination can identify children at increased risk for significant heart disease. Pathologic causes of systolic murmurs include atrial and ventricular septal defects, pulmonary or aortic outflow tract abnormalities, and patent ductus arteriosus. An atrial septal defect is often confused with a functional murmur, but the conditions can usually be differentiated based on specific physical findings. Characteristics of pathologic murmurs include a sound level of grade 3 or louder, a diastolic murmur or an increase in intensity when the patient is standing. Most children with any of these findings should be referred to a pediatric cardiologist.  (+info)

Methacholine challenge in preschool children: methacholine-induced wheeze versus transcutaneous oximetry. (5/162)

Tracheal/chest auscultation for wheeze and transcutaneous oximetry have both been suggested as measures of outcome in bronchial provocation tests in young children. This study aimed to compare the sensitivity and safety of these two techniques as end-points for methacholine challenge in children aged <4 yrs. Seventy-two methacholine challenges were performed in 39 children aged <4 yrs with recurrent wheeze. Arterial oxygen saturation (Sa,O2) and transcutaneous oxygen pressure tcPO2 continuously, and the test was terminated when wheeze was heard or at Sa,O2 <91%. tcPO2 was not used as an end-point. Wheeze or desaturation occurred at < or =8 mg x mL(-1) methacholine in every test. One child had transient clinical cyanosis, but no other ill-effects were seen. Fifty-six tests (78%) were terminated for wheeze, seven (10%) for fall in Sa,O2 and nine (12%) showed simultaneous responses in both parameters. Twenty-eight tests (39%) contained a fall in tcPO2 >3 kPa but six of these also showed a significant rise. Fifty-three tests (75%) contained a fall in tcPO2 >15%, but 20 of these also showed a significant rise. Tracheal/chest auscultation with Sa,O2 monitoring is a sensitive and relatively safe end-point for bronchial challenges in preschool children. The erratic pattern of transcutaneous oxygen pressure response in some children casts doubt on its reliability as a proxy measure of bronchial obstruction.  (+info)

Acoustic monitoring of intraoperative neuromuscular block. (6/162)

Standard methods for accurate intraoperative measurement of neuromuscular block are either expensive or inconvenient and are not used widely. We have evaluated a new method of monitoring neuromuscular block using a low-frequency microphone. The method is based on the phenomenon of low-frequency sound emission by contracting skeletal muscle. Acoustic monitoring (MIC) with an air-coupled microphone was used to evaluate intraoperative neuromuscular block in 25 anaesthetized patients. The MIC recorded the response of the adductor pollicis muscle to supramaximal electrical stimulation of the ulnar nerve with train-of-four stimuli. The ratios of the first response (TI) to control (TC) were used for evaluation. Data obtained from the MIC were compared with simultaneous recordings, from the same hand, of mechanomyography (FDT), electromyography (EMG) and accelerography (ACC). Throughout the operative procedure, TI/TC ratios of the acoustic method correlated with the three reference devices: FDT, 12 patients, 262 data sets, r = 0.86, bias (%MIC-%FDT) = mean -5.3 (SD 19.6)%; EMG, 18 patients, 490 data sets, r = 0.85, bias (%MIC-%EMG) = -0.39 (20.29)%; and ACC, 13 patients, 328 data sets, r = 0.91, bias (%MIC-%ACC) = -3.0 (15.6)%. We conclude that monitoring intraoperative neuromuscular block by a microphone which transduces low-frequency muscle sounds is clinically feasible.  (+info)

A new double cuff sphygmotonometer for accurate blood pressure measurement. (7/162)

Accurate measurement of blood pressure (BP) is essential in the diagnosis and treatment of hypertension, but neither auscultatory nor oscillometric methods measure intra-arterial BP accurately in all circumstances. Algorithms for automatic BP-measuring devices differ from manufacturer to manufacturer, and no clear authorized algorithm criteria have yet been established. We have devised a double-cuff sphygmotonometer to measure BP on the basis of clear algorithms, and investigated the accuracy of this new method by comparing it with the photo-oscillometric method, which is the most accurate method for non-invasive measurement of intra-arterial BP. In the new method, a small cuff (3x6 cm) replaces the photo-sensor in the brachial cuff (13x24 cm) of the photo-oscillometric device, and BP is determined by means of the oscillation within the small cuff. The comparison based on procedures of AAMI-protocol was performed in 136 hypertensive patients and 54 normotensive subjects. The difference in systolic BP between the photooscillometric and double-cuff methods was -2.26+/-2.31 mmHg (89% under 5 mmHg), and the corresponding difference in diastolic BP was 1.9+/-2.50 mmHg (94% under 5 mmHg). In conclusion, we have devised a new double-cuff method which improves on the photo-oscillometric method, and although it seems to be less accurate than the photo-oscillometric method, the clarity of its algorithm makes it superior to the conventional oscillometric and auscultatory methods employing only one cuff.  (+info)

The clinical evaluation of the Respi-check mask: a new oxygen mask incorporating a breathing indicator. (8/162)

Study objective-To investigate the correlation between the Respi-check sensor and simultaneous chest auscultation in determining the respiratory rates in adults. METHODS: Random visits to a local accident and emergency (A&E) department were made and all patients wearing oxygen masks were recruited into the study. The new sensor was attached to the outside of the mask. One researcher auscultated the chest to count breaths, the other counted the sensor activity. Each was blinded to the activities of the other. Breaths were counted by each researcher simultaneously and independently over one minute. A total of 40 patients were recruited into the study. A difference of more than two breaths/min compared with chest auscultation was deemed as a sensor failure. RESULTS: The respiratory rates of 40 patients were measured. There were 28 men, 12 women. Twenty six patients were wearing an Intersurgical high concentration (flow 12l/min) mask, 14 were wearing an aerosol mask with variable venturi (flow 3-12l/min) by Medicaid. Over one minute rates determined by the two methods were the same in 28 cases (70%). It was accurate to within one breath in 37 cases (93%) and to within two breaths in 39 (98%) cases and in one case (2.5%) the sensor failed. The mean difference (mean of the differences between rates obtained from auscultation and the new sensor) was -0.1282 breaths/min, with limits of agreement (d (2SD) between -1.414 to 1.157 breaths/min. CONCLUSION: The Respi-check sensor provides an accurate method of estimating the respiratory rate in adult patients attending the A&E department.  (+info)

Though lung sounds auscultation is important for the diagnosis and monitoring of lung diseases, the spectral characteristics of lung sounds have not been fully understood. This study compared the spectral characteristics of lung sounds between the right and left lungs and between healthy male and female subjects using a dual-channel auscultation system. Forty-two subjects aged 18-22 years without smoking habits and any known pulmonary diseases participated in this study. The lung sounds were recorded from seven pairs of auscultation sites on the chest wall simultaneously. We found that in four out of seven auscultation pairs, the lung sounds from the left lung had a higher total power (PT) than those from the right lung. The PT of male subjects was higher than that of female ones in most auscultation pairs. The ratio of inspiration power to expiration power (RI/E) of lung sounds from the right lung was greater than that from the left lung at auscultation pairs on the anterior chest wall, while this

Respiratory sound analysis is a simple and noninvasive way to study the pathophysiology of the upper airway (UA). Recently, it has been used to diagnose partial or complete UA collapse in patients with obstructive sleep apnea (OSA). In this study, we investigated whether fluid accumulation in the neck alters the properties of respiratory sounds in temporal and spectral domains and whether the respiratory sounds analysis can be used to monitor variations in the physiology of the UA, as rejected by UA resistance (R(UA)). We recorded respiratory sounds and R(UA) from 19 individuals while awake. We applied lower body positive pressure (LBPP) to shift fluid out of the legs and into the neck, which increased R(UA). We calculated first and second formants and energy of inspiratory sound segments. Our results show that during both control (no LBPP) and LBPP arms of the study, the extracted features were different for the sound segments corresponding to low and high R(UA). Also, the features were ...
Breath sounds are the sounds made by air as it moves through the respiratory system. Breath sounds are also called lung sounds or respiratory sounds. Sometimes they can be heard by anyone; other times they can be heard only by listening to the lungs and airways with a stethoscope.[1] To describe and identify breath sounds, medical professionals usually use auscultation (they listen with a stethoscope). They listen while the patient is breathing in, and while they are breathing out. They listen to both lungs, at both the chest and the back, starting at the bottom and working their way up. They listen to whether the pitch of the breath sounds is low, medium or high. They also listen to whether the sounds are soft, medium, loud, or very loud).[2] ...

The Liver scratch test is a method medical professionals use in ascertaining the location and size of a patients liver during a physical assessment. It is often used when other techniques, such as the hepatojugular reflux test either fail or are ineffective, most often due to abdominal distention or muscle tenseness. The Liver scratch test uses auscultation to detect the differences in sound transmission through the abdominal cavity over solid and hollow organs and spaces. After placing a stethoscope over the approximate location of a patients liver, a medical professional will then scratch the skin of the patients abdomen lightly, moving laterally along the liver border. When the liver is encountered, the scratching sound heard in the stethoscope will increase significantly. In this manner, the size and shape of a patients liver can be ascertained.

Bruit (English: /ˈbruːi/; from French, noise), or vascular murmur, is the abnormal sound generated by turbulent flow of blood in an artery due to either an area of partial obstruction; or a localized high rate of blood flow through an unobstructed artery. The bruit may be heard (auscultated) by pressing a stethoscope to the skin over the turbulent flow and listening. Most bruits occur only in systole, so the bruit is intermittent and its frequency dependent on the heart rate. Anything increasing the blood flow velocity such as fever, anemia, or hyperthyroidism, can increase the amplitude of the bruit.

RESULTS The incidence of amputation was 5.6% in men and 5.3% in women. High fasting plasma glucose at baseline examination and the duration of diabetes were associated with a twofold risk for amputation. Similarly, glycemic control measured at baseline by HbA1 was an important predictor of amputation. There was a dose-response relationship between plasma glucose or HbA1 and the risk for amputation. The effect of hyperglycemia on the risk of amputation was seen clearly even after the adjustment for other cardiovascular risk factors. Signs of peripheral neuropathy and bilateral absence of Achilles tendon reflexes and vibration sense were important predictors for amputation. Furthermore, absent peripheral artery pulses and femoral artery bruit on auscultation predicted amputation.. ...

By comparison, vesicular breathing (the sound you should hear over the lungs) has a rustling quality which builds up from the onset of inspiration to expiration, where it tails off such that it is not heard in the latter half of expiration. The important difference is that with vesicular breath sounds there is no gap between inspiration and expiration, Ive attempted to explain this below.. I think the concepts of bronchial and vesicular breathing are quite difficult to grasp, but I found it so much easier when I considered this alongside Mr Rs diagnoses, so I will begin with these.. Mr R has suffered from pulmonary oedema (secondary to his left heart failure, which is secondary to his pernicious anaemia) in the past, and I suspect that he was suffering from it when I examined him. The cyanosis I observed, and crepitations I heard on auscultation are consistent with this.. Furthermore, Mr R has been diagnosed with pulmonary fibrosis (working as a coal miner and smoking 26 pack years are both ...

History, physical examination and lung physiology. IPF has an insidious onset. It often presents with persistent dry cough associated with worsening breathlessness and progressive decline in ones exercise capacity. Hemoptysis (coughing up blood) is rare and if it occurs other causes of interstitial lung diseases, such as vasculitis and Iymphangioleiomyomatosis (LAM), should be considered. Most patients with IPF have inspiratory dry crackles (velcro-type) on auscultation of the chest. Clubbing of the fingers occurs in about half the cases. More advanced cases may present with signs of pulmonary hypertension such as right ventricular heave, loud P2 and tricuspid regurgitation murmur. Pulmonary function tests (PFTs) typically will demonstrate a restrictive defect, with decreased FVC and TLC, associated with impaired diffusion capacity and often hypoxemia at rest or exercise.. The radiographic patterns of IPF. H. Bobby Nath, MD - Professor of Radiology Plain chest radiographs are seldom helpful ...
A 62 year old woman was referred to hospital by her general practitioner because of a few days history of progressive shortness of breath. She had associated fever but no cough or sputum production. Her medical history included rheumatoid arthritis, for which she had been taking methotrexate for the past 12 years.. On examination, she was visibly dyspnoeic, with low oxygen saturations. Her respiratory rate was 22 breaths/min, oxygen saturation was 90% on air, heart rate was 100 beats/min, blood pressure was 115/72 mm Hg, and her temperature was 37.4ºC.

Clinical introduction An 88-year-old man, admitted to the emergency room (ER) after three episodes of syncope within 1 day, reported a precursory of syndrome of light-headedness with rapid palpitations that led to an abrupt loss of consciousness. After undergoing percutaneous and surgical revascularisation, he started complaining of chest and back discomfort for the past 20 years and searching for help from Chinese medicine, Fuzi. He had history of chronic renal failure and heart failure, but denied neither taking digitalis nor having family history related to sudden death.. On arrival, heart rate was 150 bpm and blood pressure (BP) by cuff was 91/81 mm Hg (non-invasive BP could not be accurately obtained during tachycardia) plus oedema on both lower extremities. There were diffuse crackles and indistinct heart sounds on auscultation.. The admission ECG was performed in the ER (figure 1). His serum creatinine was 139.7 mmol/L, serum K+ was 4.7 mmol/L, N-terminal of the prohormone brain ...

Animals with bacterial pneumonia usually have a history of a productive cough, fever, tachypnea, and respiratory distress. However, some animals (and particularly cats) present with more vague signs of illness, such as malaise, depression, anorexia, and weight loss. An early clue to the diagnosis of bacterial pneumonia is a change in the respiratory pattern. Parenchymal infection with alveolar flooding by inflammatory debris leads to restrictive lung disease, and a rapid shallow breathing pattern results. Thoracic auscultation is typically abnormal with loud or harsh lung sounds, and crackles can be variably detected throughout the lung fields. Absence of lung sounds in an area is suggestive of lung consolidation. A mucopurulent nasal discharge can be observed when animals cough respiratory secretions into the nasopharynx or have concurrent nasal infection. Fever may or not be present. These general rules are followed much more closely in dogs than in cats, in which bacterial pneumonia can ...
A lung sound diagnostic system for use in collecting, organizing and analyzing lung sounds associated with the inspiration(s) and expiration(s) of a patient. The system includes a plurality of transducers that may be placed at various sites around the patients chest. The microphones are coupled to signal processing circuitry and A/D converters which digitize the data and preferably provides the digital data to a computer station. A data collection and organization program, executing on the computer station, organizes and formats the data into a combination display for display or printing. The combinational display includes at least two display elements. In a first display element, the data is shown for both inspiration and expiration combined in a first time scale. In a second display element, the data for inspiration and expiration are shown individually in a second time scale that is time-expanded relative to the first time scale. The system may also include application programs for detecting
It is valuable to perform a pulsus paradoxous in this and other conditions. The pulsus paradoxus is inaptly named because it is actually an exaggeration of a normal phenomenon. To measure it, take a blood pressure with auscultation - when deflating the cuff slowly, you will hear Korotkoff sounds only on expiration beginning at a certain pressure. Note this pressure and continue - you will then hear the sounds throughout the respiratory cycle. The difference between those two pressures is the pulsus paradoxus. Many have suggested that this phenomenon occurs due to reduced pulmonary vascular resistance upon inspiration, increased venous inflow into the RA/RV, and then septal bowing into the LV impairing LV outflow. While this makes sense, it is not seen echocardiographically even during tamponade. Instead, the mechanism is thought to be related to the gradient of pressure in the pulmonary veins (mostly affected by the intrathoracic pressure) and the left atrium (mostly affected by pericardial ...
Helpful, trusted answers from doctors: Dr. Kim on can bruits change their sound as time passes: Bruits can change their sound depending on the degree of blockage. In the carotid arteries, for example, as a blockage is almost complete ( | 90%), the bruit actually goes away! this is why a bruit is not the best way to evaluate someone for carotid disease. An ultrasound is much more accurate!
I have read that the scratch test is only about 50% accurate for positive results. That is why a diagnosis looks at more than the test. There is a family history taken along with any other signs of allergy (has the child reacted to the specific food, have ezcema or asthma). A Rast test will also help the allergist with a diagnosis. When a scratch test is done there is also a positive and negative control test done too. Did the allergist not explain this to you? Its amazing how little info is passed on sometimes ...

... s are due to the rupture of a blood vessel within the richly perfused nasal mucosa. Rupture may be spontaneous or initiated by trauma. Nosebleeds are reported in up to 60% of the population with peak incidences in those under the age of ten and over the age of 50 and appear to occur in males more than females.[6] An increase in blood pressure (e.g. due to general hypertension) tends to increase the duration of spontaneous epistaxis.[7] Anticoagulant medication and disorders of blood clotting can promote and prolong bleeding. Spontaneous epistaxis is more common in the elderly as the nasal mucosa (lining) becomes dry and thin and blood pressure tends to be higher. The elderly are also more prone to prolonged nose bleeds as their blood vessels are less able to constrict and control the bleeding.. The vast majority of nose bleeds occur in the anterior (front) part of the nose from the nasal septum. This area is richly endowed with blood vessels (Kiesselbach's plexus). This region is also ...
A symptom (from Greek σύμπτωμα, "accident, misfortune, that which befalls",[1] from συμπίπτω, "I befall", from συν- "together, with" and πίπτω, "I fall") is a departure from normal function or feeling which is apparent to a patient, reflecting the presence of an unusual state, or of a disease. A symptom can be subjective or objective. Tiredness is a subjective symptom whereas cough or fever are objective symptoms.[2] In contrast to a symptom, a sign is a clue to a disease elicited by an examiner or a doctor.[3] For example, paresthesia is a symptom (only the person experiencing it can directly observe their own tingling feeling), whereas erythema is a sign (anyone can confirm that the skin is redder than usual). Symptoms and signs are often nonspecific, but often combinations of them are at least suggestive of certain diagnoses, helping to narrow down what may be wrong. In other cases they are specific even to the point of being pathognomonic. The term is sometimes also ...
... s are normally waited out, as any fit of them will usually pass quickly. Folkloric 'cures' for hiccups are common and varied, but no effective standard for stopping hiccups has been documented. Hiccups are treated medically only in severe and persistent (termed "intractable") cases. Numerous medical remedies exist but no particular treatment is known to be especially effective, generally because of a paucity of high-quality evidence.[15][16] Many drugs have been used, such as baclofen, chlorpromazine, metoclopramide, gabapentin, and various proton-pump inhibitors. Hiccups that are secondary to some other cause like gastroesophageal reflux disease or esophageal webs are dealt with by treating the underlying disorder. The phrenic nerve can be blocked temporarily with injection of 0.5% procaine, or permanently with bilateral phrenicotomy or other forms of surgical destruction. Even this rather drastic treatment does not cure some cases, however. An anecdotal medical approach is to install ...
Even when marked, hypocapnia is normally well tolerated. Symptoms include tingling sensation (usually in the limbs), abnormal heartbeat, painful muscle cramps, and seizures. Acute hypocapnia causes hypocapnic alkalosis, which causes cerebral vasoconstriction leading to cerebral hypoxia, and this can cause transient dizziness, fainting, and anxiety.[1] A low partial pressure of carbon dioxide in the blood also causes alkalosis (because CO2 is acidic in solution), leading to lowered plasma calcium ions and increased nerve and muscle excitability. This explains the other common symptoms of hyperventilation -pins and needles, muscle cramps and tetany in the extremities, especially hands and feet.[citation needed] Because the brain stem regulates breathing by monitoring the level of blood CO2 instead of O2, hypocapnia can suppress breathing to the point of blackout from cerebral hypoxia, as exhibited in shallow water blackout. Hypocapnia also results in bronchoconstriction[1] in order to decrease ...
Compressive asphyxia (also called chest compression) is mechanically limiting expansion of the lungs by compressing the torso, hence interfering with breathing. Compressive asphyxia occurs when the chest or abdomen is compressed posteriorly.[7] "Traumatic asphyxia" or "crush asphyxia" usually refers to compressive asphyxia resulting from being crushed or pinned under a large weight or force. An example of traumatic asphyxia includes cases where an individual has been using a car-jack to repair a car from below, and is crushed under the weight of the vehicle.[5] Pythons, anacondas, and other constrictor snakes kill through compressive asphyxia. In cases of co-sleeping ("overlay"), the weight of an adult or large child may compress an infant's chest, preventing proper expansion of the chest. Risk factors include large or obese adults, parental fatigue or impairment (sedation by drugs or alcohol) of the co-sleeping adult and a small shared sleeping space (for example, both adult and infant sharing ...
Different physiological pathways may lead to shortness of breath including via ASIC chemoreceptors, mechanoreceptors, and lung receptors.[14] It is thought that three main components contribute to dyspnea: afferent signals, efferent signals, and central information processing. It is believed the central processing in the brain compares the afferent and efferent signals; and dyspnea results when a "mismatch" occurs between the two: such as when the need for ventilation (afferent signaling) is not being met by physical breathing (efferent signaling).[19] Afferent signals are sensory neuronal signals that ascend to the brain. Afferent neurons significant in dyspnea arise from a large number of sources including the carotid bodies, medulla, lungs, and chest wall. Chemoreceptors in the carotid bodies and medulla supply information regarding the blood gas levels of O2, CO2 and H+. In the lungs, juxtacapillary (J) receptors are sensitive to pulmonary interstitial edema, while stretch receptors signal ...
An international respiratory research group composed of members from Canada, France, and Japan proposed that the hiccup is an evolutionary remnant of earlier amphibian respiration.[13] Amphibians such as tadpoles gulp air and water across their gills via a rather simple motor reflex akin to mammalian hiccuping. The motor pathways that enable hiccuping form early during fetal development, before the motor pathways that enable normal lung ventilation form. Thus, the hiccup is evolutionarily antecedent to modern lung respiration. Additionally, this group (C. Straus et al.) points out that hiccups and amphibian gulping are inhibited by elevated CO2 and may be stopped by GABAB receptor agonists, illustrating a possible shared physiology and evolutionary heritage. These proposals may explain why premature infants spend 2.5% of their time hiccuping, possibly gulping like amphibians, as their lungs are not yet fully formed.[14] Fetal intrauterine hiccups are of two types. The physiological type occurs ...

Enlarged adenoids can become nearly the size of a ping pong ball and completely block airflow through the nasal passages. Even if enlarged adenoids are not substantial enough to physically block the back of the nose, they can obstruct airflow enough so that nasal breathing requires an uncomfortable amount of work, and inhalation occurs instead through mouth breathing. Adenoids can also obstruct the nasal airway enough to affect the voice without actually stopping nasal airflow altogether.[1] Nasal blockage is determined by at least two factors: 1) the size of the adenoids, and 2) the size of the nasal pharynx passageway. The adenoid usually reaches its greatest size by about age 5 years or so, and then fades away ("atrophies") by late childhood - generally by the age of 7 years. The lymphoid tissue remains under the mucosa of the nasopharynx, and could be seen under a microscope if the area was biopsied, but the mass is so reduced in size that the roof of the nasopharynx becomes flat rather than ...
