OSHA standards govern workplace safety, ensuring technologists have training, protective equipment, and safe working environments. NFPA covers fire codes, FDA regulates chambers, and UHMS sets medical indications.

Decompression tables are standardized to provide safe, evidence-based schedules for pressure reduction, minimizing the risk of decompression sickness. They balance nitrogen elimination with oxygen exposure limits. While they may influence treatment time and chamber efficiency, the primary goal is patient safety and consistency across facilities.

Vomiting inside an oxygen hood creates aspiration risk. The hood must be removed immediately, the airway cleared, and the patient stabilized. Treatment may resume once the patient is safe.

Nasal congestion or sinus infection can impair equalization, leading to sinus squeeze or ear barotrauma during pressurization. While infection control is important, the primary concern is mechanical obstruction of air passageways.

Type II decompression sickness involves serious neurological, spinal, or cardiopulmonary symptoms caused by nitrogen bubbles in the central nervous system. This requires urgent recompression with oxygen.
