Glossopharyngeal breathing

Mitchell D Reed, Kimberly E Iceman, Michael B Harris, Barbara E Taylor
The development of amphibian breathing provides insight into vertebrate respiratory control mechanisms. Neural oscillators in the rostral and caudal medulla drive ventilation in amphibians, and previous reports describe ventilatory oscillators and CO2 sensitive regions arise during different stages of amphibian metamorphosis. However, inconsistent findings have been enigmatic, and make comparisons to potential mammalian counterparts challenging. In the current study we assessed amphibian central CO2 responsiveness and respiratory rhythm generation during two different developmental stages...

Pulmonary hyperinflation attained by glossopharyngeal insufflation (GPI) challenges the circulation by compressing the heart and pulmonary vasculature. Our aim was to determine the amount of blood translocated from the central blood volume during GPI. Cardiac output and cardiac chamber volumes were assessed by magnetic resonance imaging in twelve breath-hold divers at rest and during apnea with GPI. Pulmonary blood volume was determined from pulmonary blood flow and transit times for gadolinium during first-pass perfusion after intravenous injection...

BACKGROUND: People with cervical spinal cord injury have impaired function of the respiratory muscles, which results in reduced ventilation. Glossopharyngeal insufflation/breathing increases total lung capacity and improves cough function, however, knowledge of the experiences regarding learning and practicing glossopharyngeal insufflation in everyday life is missing. PURPOSE: To describe and explore the experiences of learning and practicing glossopharyngeal insufflation among people with cervical spinal cord injury...

PURPOSE: Trained breath-hold divers hyperinflate their lungs by glossopharyngeal insufflation (GPI) to prolong submersion time and withstand lung collapse at depths. Pulmonary hyperinflation leads to profound hemodynamic changes. METHODS: Thirteen divers performed preparatory breath-holds followed by apnea with GPI. Filling of extrathoracic veins was determined by ultrasound and magnetic resonance imaging and peripheral extravasation of fluid was assessed by electrical impedance...

Dive-related injuries are relatively common, but almost exclusively occur in recreational or scuba diving. We report 2 children with acute central nervous system complications after breath-hold diving. A 12-year-old boy presented with unilateral leg weakness and paresthesia after diving beneath the water surface for a distance of ∼25 m. After ascent, he suddenly felt extreme thoracic pain that resolved spontaneously. Neurologic examination revealed right leg weakness and sensory deficits with a sensory level at T5...

OBJECTIVE: The glossopharyngeal insufflation maneuver (lung packing) is largely performed by competitive breath-hold divers to improve their performance, despite observational evidence of fainting and loss of consciousness in the first seconds of apnea. METHODS: We describe here the time course of hemodynamic changes, induced by breath-holding with and without lung packing, in 2 world-class apnea competitors. RESULTS: When compared with apnea performed after a deep breath (100% vital capacity), lung packing leads to a decrease in cardiac output, blood pressure, and cerebral blood flow during the first seconds after the beginning of apnea...

OBJECTIVE: To measure the upper airway of obstructive sleep apnea-hypopnea syndrome by speed CT. We can predict the airway obstruction plane with the airway plane data and compliance in OSAHS patients. Through this measurement, we can provide assistance for clinical diagnosis and treatment. METHOD: This study randomly selected 82 patients diagnosed with OSAHS and 45 cases non-snoring healthy people as control group by the PHILIPS 256-slice CT. The zone volume, sagittal diameter, coronary diameter and cross-sectional area of the narrowest plane in nasopharyngeal area, velopharyngeal area, glossopharyngeal area, hypopharynx area in two groups of quiet respiration and Müller's status were measured...

Breath-hold divers report transient, severe neurological symptoms that could be caused by arterial gas embolism after glossopharyngeal insufflation. This technique is often used to overinflate the lungs and stretch the chest prior to breath-holding and can increase the transpulmonary pressure to around 7-8 kPa, so introducing risk of pulmonary barotrauma. Airway pressure, blood pressure and static spirometry (nitrogen dilution) were measured simultaneously in ten subjects attempting to identify individuals at risk...

This article describes noninvasive acute and long-term management of the respiratory muscle paralysis of high spinal cord injury (SCI). This includes full-setting, continuous ventilatory support by noninvasive intermittent positive pressure ventilation (NIV) to support inspiratory muscles and mechanically assisted coughing (MAC) to support inspiratory and expiratory muscles. The NIV and MAC can also be used to extubate or decannulate 'unweanable' patients with SCI, to prevent intercurrent respiratory tract infections from developing into pneumonia and acute respiratory failure (ARF), and to eliminate tracheostomy and resort to costly electrophrenic/diaphragm pacing (EPP/DP) for most ventilator users, while permitting glossopharyngeal breathing (GPB) for security in the event of ventilator failure...

This case report describes the effects of glossopharyngeal breathing on respiration and speech in a patient with tetraplegia due to multiple sclerosis. Glossopharyngeal breathing is a technique where air is insufflated with the glossopharyngeal muscles, to increase vital capacity. Results from follow-up assessments up to 20 months after intervention showed that (1) the patient's speech and respiratory function with glossopharyngeal breathing improved over time, (2) the patient's respiratory function without glossopharyngeal breathing deteriorated over time (possibly because of a severe cold), and (3) at each assessment, the patient's speech and respiratory function was better with glossopharyngeal breathing than without it...

Pierre-Robin syndrome (PRS) is often associated with difficulty in endotracheal intubation. We present the use of percutaneous dilational tracheotomy (PDT) for airway management of a newborn with PRS and a glossopharyngeal web. A 2-day-old term newborn with PRS and severe obstructive dyspnea was evaluated by the anesthesiology team for airway management. A direct laryngoscopy revealed a glossopharyngeal web extending from the base of the tongue to the posterior pharyngeal wall. The infant was spontaneously breathing through a 2 mm diameter fistula in the center of this web...

Lung volume recruitment can improve peak cough flows and respiratory compliance in patients who either do or do not require mechanical ventilation. There are several lung volume recruitment techniques: air stacking, glossopharyngeal breathing and mechanical insufflation-exsufflation with cough assist devices. The principle of lung volume recruitment is based on the insufflation of air in the lungs after maximal inspiration. In air stacking, a manual resuscitation bag is used for insufflation. Glossopharyngeal breathing requires the use of oropharyngeal and laryngeal muscles by the patient...

PURPOSE: Apnea divers hyperinflate the lung by taking a deep breath followed by glossopharyngeal insufflation. The maneuver can lead to symptomatic arterial hypotension. We tested the hypotheses that glossopharyngeal insufflation interferes with cardiac function further reducing cardiac output (CO) using cardiac magnetic resonance imaging (MRI) to fully sample both cardiac chambers. METHODS: Eleven dive athletes (10 men, 1 woman; age = 26 ± 5 yr, body mass index = 23...

PURPOSE: Extensive breath-hold (BH) diving imposes high pulmonary stress by performing voluntary lung hyperinflation maneuvers (glossopharyngeal insufflation, GI), hyperinflating the lung up to 50% of total lung capacity. Breath-hold durations of up to 10 min without oxygen support may also presume cerebral alterations of respiratory drive. Little is known about the long-term effects of GI onto the pulmonary parenchyma and respiratory adaptation processes in this popular extreme sport...

Punctate reopening of the lung from subresidual volumes (sub-RV) is commonly observed in excised lung preparations, either degassed or collapsed to zero transpulmonary pressure, and in the course of reinflation of human lungs when the chest is open, secondary to traumatic or surgical pneumothoraxes. In the course of physiological studies on two elite breath-hold divers, who are able to achieve lung volumes well below traditional RV with glossopharyngeal exsufflation, we used MRI lung imaging with inhaled hyperpolarized (129)Xe to visualize ventilatory patterns...
