  • What Chamber Operators Should Know About Ear Barotrauma (And How to Prevent It) Robert Sheffield, CHT and Kevin “Kip” Posey, CHT / June 2018
    LEARN.HYPERBARICMEDICINE.COM International ATMO Education What Chamber Operators Should Know About Ear Barotrauma (and How to Prevent It) Robert Sheffield, CHT and Kevin “Kip” Posey, CHT / June 2018 INTRODUCTION Ear barotrauma (i.e. “ear block”, “ear squeeze”) is the most common complication of hyperbaric treatment. It occurs when the pressure in the hyperbaric chamber is greater than the pressure in the middle ear. It is prevented by patient assessment, patient education, and the appropriate actions of the chamber operator. The chamber operator has an important role in preventing ear barotrauma in hyperbaric patients. OBJECTIVES At the conclusion of this article, the reader will be able to: Describe the anatomy of the middle ear Explain the mechanism of ear barotrauma Describe 3 techniques to equalize middle ear pressure ANATOMY OF THE MIDDLE EAR The middle ear is an air space that separates the external ear canal from the inner ear. The eardrum, called the tympanic membrane (TM), vibrates when sound enters the ear canal. The vibration is transmitted to a series of bones in the middle ear. These bones transmit vibration to another membrane (the oval window) that separates the air‐filled middle ear from the fluid‐filled inner ear, where sound is sensed in the cochlea. The nasopharynx is the area behind the nose and above the palate. The Eustachian tubes open into this area. Because of the location of the Eustachian tube openings, the same things that cause nasal congestion (e.g. allergies, upper respiratory infection) can cause swelling around the opening of the Eustachian tubes, making it more difficult to equalize pressure in the middle ear.

However, due to a low overall incidence, it may go undiagnosed. Case Report: A 56-year-old man with a medical history of right upper lobectomy due to lung cancer showed changes in mental status after the Valsalva maneuver, followed by status epilepticus during admission. Brain and chest computed tomography showed cerebral air embolism and accidental pneumothorax in the right major fissure. After antiepileptic drug infusion and oxygen therapy, he recov- ered completely. Conclusion: Since cerebral air embolism may result in fatal outcomes, it should be suspected in patients with sudden neurological de- terioration after routine medical procedures.

  • Middle Ear Barotrauma After Hyperbaric Oxygen Therapy - the Role of Insuflation Maneuvers
    DOI: 10.5935/0946-5448.20120032 ORIGINAL ARTICLE International Tinnitus Journal. 2012;17(2):180-5. Middle ear barotrauma after hyperbaric oxygen therapy - the role of insuflation maneuvers Marco Antônio Rios Lima1 Luciano Farage2 Maria Cristina Lancia Cury3 Fayez Bahmad Jr.4 Abstract Objective: To analyze the association of insuflation maneuvers status before hyperbaric oxygen therapy with middle ear barotrauma. Materials and Methods: Fouty-one patients (82 ears) admitted to the Department of Hyperbaric Medicine from May 2011 to July 2012. Assessments occurred: before and after the first session, after sessions with symptoms. During the evaluations were performed: otoscopy with Valsalva and Toynbee maneuvers, video otoscopy and specific questionnaire. Middle ear barotrauma was graduated by the modified Edmond’s scale. Tubal insuflation was classified in Good, Median and Bad according to combined results of Valsalva and Toynbee maneuvers. Inclusion criteria: patients evaluated by an otolaryngologist before and after the first session, with no history of ear disease, who agreed to participate in the research (convenience sample). Results: Of the 82 ears included in the study, 32 (39%) had barotrauma after the first session. The rate of middle ear barotrauma according to tubal insuflation was: 17.9% (Good insuflation) 44.4% (Median insuflation) and 55.6% (Bad insuflation)P ( = 0.013). Conclusion: Positive Valsalva and Toynbee maneuvers before the first session, alone or associated were protective factors for middle ear barotrauma by ear after the first session. Keywords: barotrauma, hyperbaric oxygenation, middle ear ventilation. 1 Health Science School - University of Brasília - Brasília - DF - Brasil.

  • “EARLY and OFTEN - WHEN?” By: George Safirowski
    “EARLY AND OFTEN - WHEN?” by: George Safirowski One of the basic skills that each scuba student must learn early in an open water basic certification course is equalization of pressure on decent. The process of equalization is necessary every time we go diving, since air spaces in the middle ear are of particular importance because even a minor pressure imbalance can result in an injury. The technique involved in preventing ear squeeze is easy to learn, and instructions are very simple - “equalize early and often”. But what does early and often really mean? While teaching hundreds of scuba divers trained and certified by various organizations gave me an opportunity to observe that the majority of newly and many “experienced” divers have a problem deciding when it is early enough, and how often they should equalize. To prevent ear squeeze, a diver must begin the equalization process prior to any sensation of discomfort or pain. Pain is a symptom of tissue damage and swelling taking place in the air passages, further restricting comfortable equalization. Therefore, using pain as an indicator to begin equalization means it is already too late. Tissue damage within the ear also renders itself to ear infections due to the already injured tissue being exposed to the surrounding environment and having little resistance against the soup of microscopic creatures. Often a dive vacation turns out to be a bust caused by external otitis. While diving, there is absolutely no reason to continue with decent if equalization was not successful at a shallower depth. Often peer pressure and lack of buoyancy control are major contributors in equalization difficulties.

  • A Water-Filled Body Plethysmograph for the Measurement of Pulmonary Capillary Blood Flow During Changes of Intrathoracic Pressure
    A water-filled body plethysmograph for the measurement of pulmonary capillary blood flow during changes of intrathoracic pressure Yoshikazu Kawakami, … , Harold A. Menkes, Arthur B. DuBois J Clin Invest. 1970;49(6):1237-1251. https://doi.org/10.1172/JCI106337. Research Article A water-filled body plethysmograph was constructed to measure gas exchange in man. As compared to an air-filled plethysmograph, its advantages were greater sensitivity, less thermal drift, and no change from adiabatic to isothermal conditions after a stepwise change of pressure. When five subjects were completely immersed within it and were breathing to the ambient atmosphere, they had a normal heart rate, oxygen consumption, CO2 output, and functional residual capacity. Pulmonary capillary blood flow ([unk]Qc) during and after Valsalva and Mueller maneuvers was 2 calculated from measurements of N2O uptake. Control measurements of [unk]Qc were 2.58 liters/min per m at rest and 3.63 liters/min per m2 after moderate exercise. During the Valsalva maneuver at rest (intrapulmonary pressure: 24, SD 3.0, mm Hg), [unk]Qc decreased from a control of 2.58, SD 0.43, liters/min per m2 to 1.62, SD 0.26, liters/min per m2 with a decrease in pulmonary capillary stroke volume from a control of 42.4, SD 8.8, ml/stroke per m2 to 25.2, SD 5.5, ml/stroke per m2. After release of the Valsalva, there was an overshoot in [unk]Qc averaging +0.78, SD 0.41, liter/min per m2 accompanied by a significant increase in heart rate. Similar changes occurred during and after the Valsalva following moderate exercise.

The incidence of MEB has been shown to vary between treatment centers and patients. This study was aimed to determine which patients are at high risk of MEB. Materials and methods: Prospective study including all the patients treated in a multiplace HBO2 chamber between January and December 2005. Scoring of MEB before and after HBO2 by otoscopy was performed using the Haines and Harris classification. Results: We included 130 patients: 53 Males, 37.5 ± 20.5 years old; 76% were treated for CO poisoning, 11% for iatrogenic gas embolism, 12% for decompression sickness and 4% for necrotizing soft tissue infection. 13% were intubated. MEB occurred in 13.6% of the patients (12.4% of the conscious and 24.4% of the intubated patients, p=0.26). Risk factors for MEB were: repetitive treatments and difficulties with pressure equalization. There was no influence of age, sex or mechanical ventilation on the occurrence of MEB. Conclusions: MEB induced by HBO2 occurred in 13.6% of the patients.

  • Impairment of Sympathetic Activation During Static Exercise in Patients with Muscle Phosphorylase Deficiency (Mcardle's Disease)
    Impairment of sympathetic activation during static exercise in patients with muscle phosphorylase deficiency (McArdle's disease). S L Pryor, … , L A Bertocci, R G Victor J Clin Invest. 1990;85(5):1444-1449. https://doi.org/10.1172/JCI114589. Research Article Static exercise in normal humans causes reflex increases in muscle sympathetic nerve activity (MSNA) that are closely coupled to the contraction-induced decrease in muscle cell pH, an index of glycogen degradation and glycolytic flux. To determine if sympathetic activation is attenuated when muscle glycogenolysis is blocked due to myophosphorylase deficiency (McArdle's disease), an inborn enzymatic defect localized to skeletal muscle, we now have performed microelectrode recordings of MSNA in four patients with McArdle's disease during static handgrip contraction. A level of static handgrip that more than doubled MSNA in normal humans had no effect on MSNA and caused an attenuated rise in blood pressure in the patients with myophosphorylase deficiency. In contrast, two nonexercise sympathetic stimuli, Valsalva's maneuver and cold pressor stimulation, evoked comparably large increases in MSNA in patients and normals. The principal new conclusion is that defective glycogen degradation in human skeletal muscle is associated with a specific reflex impairment in sympathetic activation during static exercise.
