The COMEX-30 hyperbaric treatment table is used to
manage decompression sickness in divers but may result in
pulmonary oxygen toxicity (POT). Volatile organic
compounds (VOCs) in exhaled breath are early markers of
hyperoxic stress that may be linked to POT. The present
study assessed whether VOCs following COMEX-30
treatment are early markers of hyperoxic stress and/or POT
in ten healthy, nonsmoking volunteers.

Exposure to acute hypoxia elicits several functional
changes in the human body to cope with the decreased
oxygen availability. Whereas some of these adjustments
(increased pulmonary ventilation and heart rate) are well
characterized, others are still poorly understood. Excesses
in the accumulation of reactive oxygen species (ROS),
generated within the mitochondria, drive mechanisms
contributing to injury including the induction of oxidative
damage.

Conductive gels have been developing as superior
wearable sensing materials due to their intrinsic
conductivity, softness, stretchability, and biocompatibility,
showing great potential in many aspects of our lives.
However, it is challenging for traditional conductive gels to
realize sensing applications underwater. The swelling of
gels and the loss of conductive components in the
aqueous environment, resulting from the diffusion across
the interface, lead to structural instability and sensing
performance decline. Fortunately, significant efforts have
been devoted to improving the water resistance of
conductive gels and employing them in underwater
wearable sensing in recent years, and some are exciting.

The authors suspected that oxygen uptake (VO2) and
pulmonary ventilation (VE) might be much higher than
expected during military fin swimming. In this framework,
they compared these variables in the responses of trained
military divers during land cycling and snorkeling exercises:
Eighteen male military divers participated in this study.
They performed two test exercises on two days: A maximal
incremental cycle test (land condition), and an incremental
fin swimming (fin condition) in a motorized swimming
flume.

The author and his team suggest that in a “distal arterial
bubble formation”, in the bifurcating arterial tree, the
vessel’s wall becomes thinner and wall surface to the
volume of the vessel increases, both of these
circumstances enhance inert gas diffusion from the
surrounding tissue into the blood.

Scientific underwater exploration could benefit from
professional diving facilities. This could allow marine
research for durations far exceeding anything currently
possible. The closed-circuit rebreather
expansion provides new perspectives by unleashing divers
and their diving bell. “Under the Pole Expeditions”
developed an innovative compact underwater habitat for
this purpose.

The method described aims to treat tumor hypoxia
microbubbles comprising oxygen as a majority component
of the gas core with a stabilizing shell that may be used to
deliver and release oxygen locally at the tumor site
through ultrasound destruction. Previous work has
revealed differences in circulation half-life in vivo for
perfluorocarbon-filled microbubbles, typically used as
ultrasound imaging contrast agents, as a function of
anesthetic carrier gas.

Fatigue is a complex and often misunderstood mood.
Most biomedical researchers interested in fatigue
conceptually defining fatigue as the absence of energy.
However, Loy et al. (2018) provided evidence that
biologically energy and fatigue may indeed be two
distinct unipolar moods. Since then, multiple studies have
provided evidence that energy and fatigue may have
both distinct and overlapping biological, behavioral, and
bio-mechanical correlates.

Hyperbaric oxygen therapy (HBOT) is the standard
adjuvant treatment for life-threatening or disabling
pathologies.
Currently, mechanical and electronic variations of
implantable cardioverter-defibrillators (ICD) in hyperbaric
conditions have not been evaluated. As a result, many
patients eligible for HBOT but ICD recipients cannot
undergo this therapy, even in emergency situations.

Hyperbaric oxygen therapy (HBOT) is defined as a method
of administering inhaled oxygen (O2) for therapeutic
purposes under a pressure greater than atmospheric
pressure. The therapeutic benefits of HBO result, on the
one hand, from the physical effects linked to the increase
in barometric pressure and the partial pressure of O2 in
the tissues and, on the other hand, from the biological
effects linked to the production reactive species of O2 and
nitrogen. These are likely to interact with many molecular
processes responsible for the main anti-ischemic, pro-
healing and anti-infective effects.

Neurologic injury is relatively common in the context of
spinal surgery, and is often treated with physiotherapy,
pharmacotherapy, or surgical intervention. Emerging
evidence supports a possible role
for hyperbaric oxygen therapy (HBOT) in the treatment of
peripheral and spinal nerve injuries. The authors describe
the successful use of HBOT in improving neurologic
recovery after complex spine surgery with new-onset
postoperative unilateral foot drop.

This study investigated the metabolic responses of hypoxic
breathing for one hour to inspired fractions of 10% and
15% oxygen. To this end blood samples of 14 nonsmoking
volunteers were taken before and at 30 min, 2 h, 8 h, 24
h, and 48 h after exposure. The level of oxidative stress
was evaluated while antioxidant systems were observed in
terms of the total antioxidant capacity (TAC) and urates.

Hyperbaric air (HBA) was first used pharmaceutically in
1662 to treat lung disease. Extensive use in Europe and
North America followed throughout the 19th century to
treat pulmonary and neurological disorders.
Since that time the 78% Nitrogen fraction in HBA has
been completely displaced by 100% oxygen to create the
modern pharmaceutical hyperbaric oxygen therapy
(HBOT), a powerful treatment that is approved for multiple
indications.

The authors assumed that cognitive dysfunction and
fatigue in post-COVID syndrome are critically linked via
hypoarousal of the brain. Thus, we assessed whether tonic
alertness as a neurocognitive index of arousal is reduced in
these patients and how this relates to the level of central
nervous activation and subjective mental fatigue as further
indices of arousal.

Heart rate variability (HRV) is a useful method for studying
the autonomic nervous system (ANS). As measuring
devices have developed and become smaller, many
researchers have become interested in the possibilities of
implementing the method for diving medicine research.
The aim of this study was to review human ANS responses
in cold water diving (water temperature <5°C), and to
comprise the current knowledge of HRV studies in diving
and hyperbaric exposure into one review article.

Exertional dyspnea is the primary diagnostic symptom for
chronic cardiopulmonary disease populations. While a
number of exercise tests are used, there remains no gold
standard clinical measure of exertional dyspnea. The aim
of this review was to comprehensively describe and
evaluate all types of fixed-intensity exercise tests used to
assess exertional dyspnea in chronic cardiopulmonary
populations and, where possible, report the reliability and
responsiveness of the tests.

Using the random number table method, 40 patients with
craniocerebral injury who were treated at the First
People’s Hospital of Nantong were randomly assigned to
either the control group or the hyperbaric oxygen group,
with 20 patients in each group. The control group
received routine intervention for clinical traumatic brain
injury, while the hyperbaric oxygen group received
additional hyperbaric oxygen intervention during the 7 to
30 days of routine intervention. Indicators of oxidative
stress and nerve growth factor levels were compared
between the two groups at the time of admission and 30
days after therapy.

The aging process is characterized by reduced physical
activity, accumulation of fat, and loss of muscle mass,
resulting in weight gain and reduced cardiorespiratory
function, which leads to a loss of physical function
capacity. Therefore, the purpose of this study was to
determine the extent to which body weight and
cardiorespiratory endurance predict the physical
functional capacity of older adults in Navrongo, Ghana.
This study employed a quantitative cross-sectional design,
using a multistage sampling method with 998 participants
aged (60yrs+).

A 27-year-old experienced aphasia and other symptoms
following CO poisoning. The authors underwent speech
therapy* (speech therapy* = assessment and treatment of
communication problems and speech disorders) and
hyperbaric oxygen treatments for two months. This
combined approach effectively resolved the patient's
symptoms. Further research is needed, but this case shows
promise for treating similar conditions post-CO intoxication.

The measurement of phase angle by bioimpedance
analysis (BIA) is an indicator of "cellular health”, broadly
related to cellular water balance, membrane integrity, and
cell mass. However, much of the research is based on
empirical observations and less on the biophysical
principles of BIA or an explanation of the reasoning
behind the results.This review aims to clarify the electrical
models used to describe tissue properties, with a focus on
phase angle. It also highlights practical issues in measuring
phase angle and the advantages of using bioimpedance
spectroscopy (BIS).

This study examined the vulnerability of military divers to
non-freezing cold injury (NFCI) during Arctic ice-diving
operations. It involved monitoring the temperature of
divers' extremities to assess the risk of NFCI and found that
the feet were particularly vulnerable. It also compared the
thermal comfort and protective qualities of different diving
suit configurations and highlighted the need for further
investigation into factors like hydrostatic pressure and
repetitive diving as potential risk factors for NFCI.

This document presents the ESOT (equivalent surface
oxygen time) procedure as a more practical and intuitive
alternative to the current measures (K and UPTD) for
assessing pulmonary oxygen toxicity (POT) in surface-
oriented diving. It argues that ESOT offers similar accuracy
in predicting POT while being easier to calculate and
interpret, especially in operational environments. It also
provides specific ESOT threshold limits to guide safe diving
practices over multiple days.
