Design outpatient polyclinics that can be part of a hospital or a separate building, housing examination and treatment clinics. Provide airborne infection isolation rooms and mobile Hepa filter units.

Air balance, performed by a specialist third-party contractor, measures and adjusts airflow and chilled water flows to ensure proper supply, return, extract, and room pressurization in wards and renovated departments.

Design operating rooms with laminar flow diffusers and HEPA filtration (H14), positive pressure above 10 pascals, about 20 air changes per hour, and 18–24°C with 20–60% humidity.

Explore ultraclean ventilation in operating rooms to reduce surgical site infection by keeping CFU per cubic meter low, using canopy laminar flow, HEPA filters, and variable speed fans.

Learn PICU and NICU HVAC design, featuring positive pressure, Hepa filter central supply air, 21–25°C PICU, 22–26°C NICU, 30–60% humidity, and defined air changes with isolation rooms.

Design an emergency department with 21–24°C and 30–60% relative humidity, implementing zone-specific airflow: negative pressure for waiting and triage, positive pressure for resuscitation, and 12–15 air changes per hour.

Explore hvac design for imaging rooms, detailing three class configurations: diagnostic, diagnostic-therapeutic, and hybrid operating rooms, with specific air changes and pressure requirements.

Maintain 21-24 C and 40-60% RH in MRI scanning rooms with 6 air changes; keep control and system rooms at 21-24 C and 30-60% RH under positive pressure, non-ferrous construction.

Shield the linear accelerator treatment room with concrete shielding above 100 cm, protect wall duct openings, and follow va hvac guidelines with two fresh air changes per hour.

Maintain controlled ventilation for endoscopy and bronchoscopy rooms with air changes per hour, negative pressure where needed, and HEPA-filtered fresh air. Ensure surgical scopes are processed in an operating room.

Explain eye injection settings in a clean clinic room versus the operating room, noting cleanliness standards and cost, and describe a laser eye room with positive pressure and air changes.
