  • Airway Pressures and Volutrauma
    Airway Pressures and Volutrauma Airway Pressures and Volutrauma: Is Measuring Tracheal Pressure Worth the Hassle? Monitoring airway pressures during mechanical ventilation is a standard of care.1 Sequential recording of airway pressures not only provides information regarding changes in pulmonary impedance but also allows safety parameters to be set. Safety parameters include high- and low-pressure alarms during positive pressure breaths and disconnect alarms. These standards are, of course, based on our experience with volume control ventilation in adults. During pressure control ventilation, monitoring airway pressures remains important, but volume monitoring and alarms are also required. Airway pressures and work of breathing are also important components of derived variables, including airway resistance, static compliance, dynamic compliance, and intrinsic positive end-expiratory pressure (auto-PEEP), measured at the bedside.2 The requisite pressures for these variables include peak inspiratory pressure, inspiratory plateau pressure, expiratory plateau pressure, and change in airway pressure within a breath. Plateau pressures should be measured at periods of zero flow during both volume control and pressure control ventilation. Change in airway pressure should be measured relative to change in volume delivery to the lung (pressure-volume loop) to elucidate work of breathing. See the related study on Page 1179. Evidence that mechanical ventilation can cause and exacerbate acute lung injury has been steadily mounting.3-5 While most of this evidence has originated from laboratory animal studies, recent clinical reports appear to support this concept.6,7 Traditionally, ventilator-induced lung injury brings to mind the clinical picture of tension pneumothorax. Barotrauma (from the root word baro, which means pressure) is typically associated with excessive airway pressures.

  • 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.

  • No Limits Freediving
    1 No Limits Freediving "The challenges to the respiratory function of the breath-hold diver' are formidable. One has to marvel at the ability of the human body to cope with stresses that far exceed what normal terrestrial life requires." Claes Lundgren, Director, Center for Research and Education in Special Environments A woman in a deeply relaxed state floats in the water next to a diving buoy. She is clad in a figure-hugging wetsuit, a dive computer strapped to her right wrist, and another to her calf. She wears strange form-hugging silicone goggles that distort her eyes, giving her a strange bug-eyed appearance. A couple of meters away, five support divers tread water near a diving platform, watching her perform an elaborate breathing ritual while she hangs onto a metal tube fitted with two crossbars. A few meters below the buoy, we see that the metal tube is in fact a weighted sled attached to a cable descending into the dark-blue water. Her eyes are still closed as she begins performing a series of final inhalations, breathing faster and faster. Photographers on the media boats snap pictures as she performs her final few deep and long hyperventilations, eliminating carbon dioxide from her body. Then, a thumbs-up to her surface crew, a pinch of the nose clip, one final lungful of air, and the woman closes her eyes, wraps her knees around the bottom bar of the sled, releases a brake device, and disappears gracefully beneath the waves. The harsh sounds of the wind and waves suddenly cease and are replaced by the effervescent bubbling of air being released from the regulators of scuba-divers.

    Case Report Page 1 of 6 Nursing in a critical care hyperbaric unit at Merida, Yucatan, Mexico: report of a case of an acute pediatric burn patient Judith Ruiz-Aguilar, Rodrigo Diaz-Ibañez, E. Cuauhtemoc Sanchez-Rodriguez Hyperbaric Medicine Service, Hospital Centro de Especialidades Médicas del Sureste (CEM) and Hospital Agustín O’Horan, Merida, Yucatan, Mexico Correspondence to: Judith Ruiz-Aguilar, RN, MEd. Chief of Nursing, Hyperbaric Medicine Service, Hospital Centro de Especialidades Médicas del Sureste (CEM) and Hospital Agustín O’Horan, Merida, Yucatan, Mexico. Email: [email protected]. Abstract: Hyperbaric oxygen therapy (HBOT) for intensive care unit (ICU) patients places special technical and knowledge-based skills demands on nurses inside hyperbaric chambers. Probably the best clinical contributions of HBOT are in the acute cases, in the ischemia reperfusion injury. Nevertheless in the last years, hyperbaric units have focused more in chronic wounds. The first golden rule to treat an ICU patient in a hyperbaric chamber is that you can maintain the same quality of care inside the chamber as in the ICU. This means that the hyperbaric unit has to have the technology means as well as the proficiency and competency of its personnel to provide intensive care inside the chamber. These require competent nursing personnel. We present a case of a 5-year-old pediatric patient who suffered a deep second-degree thermal burn that compromised 32% of the total body surface; including the face, neck, thorax and both arms. The patient received medical support, HBOT and daily wound care. He received a total of 14 treatments and underwent complete healing of the burned areas.

  • Consensus Conference, the ECHM
    24 Diving and Hyperbaric Medicine Volume 47 No. 1 March 2017 Consensus Conference Tenth European Consensus Conference on Hyperbaric Medicine: recommendations for accepted and non-accepted clinical indications and practice of hyperbaric oxygen treatment Daniel Mathieu, Alessandro Marroni and Jacek Kot Abstract (Mathieu D, Marroni A, Kot J. Tenth European Consensus Conference on Hyperbaric Medicine: recommendations for accepted and non-accepted clinical indications and practice of hyperbaric oxygen treatment. Diving and Hyperbaric Medicine. 2017 March;47(1):24-32.) The tenth European Consensus Conference on Hyperbaric Medicine took place in April 2016, attended by a large delegation of experts from Europe and elsewhere. The focus of the meeting was the revision of the European Committee on Hyperbaric Medicine (ECHM) list of accepted indications for hyperbaric oxygen treatment (HBOT), based on a thorough review of the best available research and evidence-based medicine (EBM). For this scope, the modified GRADE system for evidence analysis, together with the DELPHI system for consensus evaluation, were adopted. The indications for HBOT, including those promulgated by the ECHM previously, were analysed by selected experts, based on an extensive review of the literature and of the available EBM studies. The indications were divided as follows: Type 1, where HBOT is strongly indicated as a primary treatment method, as it is supported by sufficiently strong evidence; Type 2, where HBOT is suggested as it is supported by acceptable levels of evidence; Type 3, where HBOT can be considered as a possible/optional measure, but it is not yet supported by sufficiently strong evidence. For each type, three levels of evidence were considered: A, when the number of randomised controlled trials (RCTs) is considered sufficient; B, when there are some RCTs in favour of the indication and there is ample expert consensus; C, when the conditions do not allow for proper RCTs but there is ample and international expert consensus.
