There is disclosed a method and system for determining the partial pressure of at least one gas in a mixture of gasses contained in a pressure vessel, in particular a pressure vessel in the form of a life support pressure chamber/decompression chamber, or a diving gas storage cylinder. The method comprises the steps of: coupling a gas analysis sensor (14) to a pressure vessel (10); directing a portion of the mixture of gasses in the pressure vessel to the sensor for analysis; reducing the pressure of the portion of the mixture which is to be analyzed by the sensor to a level which is below the pressure in the vessel but above local atmospheric pressure; operating the sensor to measure the partial pressure of the at least one gas at the reduced pressure level; and using the partial pressure of the at least one gas, measured at the reduced pressure level, to determine the actual partial pressure of said gas in the mixture contained in the vessel.

An aerosolization mitigation device is provided. The aerosolization mitigation device can include a negative pressure aerosolization mitigation system. A transparent barrier can form a frame of the system, and a negative pressure can be generated in the internal volume. The device can isolate a patient to allow ambulatory, surgical, and routine care to proceed during periods of higher patient volume or viral transmission. The negative pressure environment mitigates viral transmission to protect healthcare providers and others in the vicinity of the patient from health risks during patient care.

A pathogen examination unit includes a working side, two non-working sides, and an entrance side. The working side of the pathogen examination unit may include a panel that is positioned between two users, such as between a healthcare worker and a patient. In some cases, the pathogen examination unit places one user, such as the healthcare worker, inside the pathogen examination unit, which reduces the number of surfaces and objects that must be disinfected between patients.

A medical containment enclosure defines an internal chamber configured to receive at least part of a patient during a medical procedure, with the enclosure operable to fluidly connect to a suction device. The enclosure includes a containment housing, an access portal, and a suction port. The containment housing at least partly defines the chamber. The access portal defines an orifice that permits chamber ingress and egress. The suction port fluidly communicates with the chamber and is fluidly connectable to the suction device to permit the suction device to draw fluid from the chamber. The access portal restricts fluid flow through the orifice so that fluid removal by the suction device is operable to reduce an internal chamber pressure below an external pressure and thereby restrict aerosols from exiting the chamber via the access portal.

Negative pressure isolation devices are disclosed to remove exhaled air from patients and to vent such air to a filter or atmosphere to protect medical personnel and others.
