Monitoring physiological biomarkers can help detect diving disorders and prevent accidents. This review explores common diving ailments and proposes using biometrics for early warnings to enhance diver safety.
Area of Science:
- Physiology
- Diving Medicine
- Biomedical Engineering
Background:
- Underwater operations pose significant physiological risks to divers.
- Diving disorders can occur during descent, at depth, ascent, and post-dive, with complex triggering factors.
- Despite safety protocols, diving incidents and disorders persist, necessitating better understanding and detection methods.
Purpose of the Study:
- To review common diving disorders and their incidence in recreational and military diving.
- To identify physiological biomarkers for monitoring diver health.
- To explore the potential of these biomarkers in detecting and preventing diving-related mishaps.
Main Methods:
- Literature review of common diving disorders and their incidence rates.
- Identification and analysis of physiological biomarkers (heart rate, HRV, blood pressure, respiration, temperature, SpO2).
- Exploration of biomarker utility in detecting specific diving disorders like decompression illness and barotraumas.
Main Results:
- Common diving disorders include decompression illnesses, gas mixture-related issues, barotraumas, and environmental exposures.
- Physiological biomarkers offer a potential holistic view of a diver's state.
- Biometric monitoring shows promise for early detection of diving disorders.
Conclusions:
- Physiological biomarkers are a promising avenue for enhancing diver safety.
- Further research is required to validate biometric systems in real-world diving conditions.
- Developing an early warning system using biometrics could significantly reduce diving accidents.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
