Decompression Sickness in the F/A-18C After Atypical Cabin Pressure Fluctuations
Aerospace Medicine and Human Performance
|April 21, 2018
Summary
Altitude decompression sickness (DCS) is challenging to diagnose, especially with atypical pressure changes in aviation. Early recognition and prompt treatment are crucial for aviator health.
Area of Science:
- Aerospace Medicine
- Physiology
- Environmental Health
Background:
- Altitude decompression sickness (DCS) diagnosis is complicated by evolving pressure fluctuations.
- Atypical pressure patterns present unique challenges for identifying DCS in aviators.
Observation:
- Two F/A-18C aviators experienced DCS after unusual cabin pressure fluctuations.
- One case involved decompression at a lower altitude than typically expected for DCS.
Findings:
- DCS diagnosis is difficult due to subtle findings, subjective symptoms, and atypical pressure profiles.
- Partial treatment with oxygen can mask DCS symptoms, delaying diagnosis.
Implications:
- Flight surgeons and Undersea Medical Officers (UMOs) must consider DCS in aviator differential diagnoses.
- Integrated squadron support and collaboration with UMOs are vital for timely DCS recognition and treatment.

925
Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...

41.1K
When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase molecules move randomly about, they will occasionally collide with the surface of the condensed phase, and in some cases, these collisions will result in the molecules re-entering the condensed phase. The change from the gas phase to the liquid is called condensation. When the rate of condensation becomes equal to the rate of vaporization, neither the amount of the liquid nor the amount of the vapor...

43.6K
Gas pressure is caused by force exerted by gas molecules colliding with the surfaces of objects. Although the force of each collision is very small, any surface of an appreciable area experiences a large number of collisions in a short time, which can result in high pressure.

97.9K
Calorimetry is a technique used to measure the amount of heat involved in a chemical or physical process or to measure the heat transferred to or from a substance. The heat is exchanged with a calibrated and insulated device called the calorimeter. Calorimetry experiments are based on the assumption that there is no heat exchange between the insulated calorimeter and the external environment. The well-insulated calorimeters prevent the transfer of heat between the calorimeter and its external...

A number of natural and synthetic materials exhibit selective permeation, meaning that only molecules or ions of a certain size, shape, polarity, charge, and so forth, are capable of passing through (permeating) the material. Biological cell membranes provide elegant examples of selective permeation in nature, while dialysis tubing used to remove metabolic wastes from blood is a more simplistic technological example. Regardless of how they may be fabricated, these materials are generally...
