The filtration enclosure for ventilation bags is a manually operated respirator. The filtration enclosure for ventilation bags is adapted for use with a patient. The filtration enclosure for ventilation bags is a breathing assistance device that maintains a positive pressure within the lungs of the patient. The filtration enclosure for ventilation bags incorporates a bag valve mask respirator and a containment structure. The containment structure forms a protection space that encloses the bag valve mask respirator such that the bag valve mask respirator can operate while within the containment space. The containment structure is formed as a gas permeable structure. The containment structure forms a filter that filters microorganisms from the gas that flows through the boundary surface formed by the containment structure.

A method alerts a user that a volume of air being circulated through a powered air purifying respirator assembly is outside an acceptable range. The powered air purifying respirator assembly includes a fan and a hood system. The method begins with the step of measuring airflow through the powered air purifying respirator assembly to create a measured airflow value. The measured airflow value is compared to a predetermined high airflow value and a predetermined low airflow value. And, after a predetermined amount of time, an alarm signal is generated when the measured airflow value is either greater than or less than the predetermined high airflow value or the predetermined low airflow value, respectively. During the time when the incorrect airflow is occurring, the motor of the fan may be adjusted to correct the airflow values before the alarm signal is generated.

A chemical protective poncho system for encapsulating a patient is presented. The system has a body extending a length between a top end and a bottom end and having a hood attached near the top end and having a liner attached near the bottom end. The system includes a layer of adsorbent impregnated media capable of filtering chemical agents while allowing oxygen and carbon dioxide to pass through the material. The chemical protective poncho is specially adapted to fit over the top of a patient and chemically seal the lower portion of the patient while allowing the patient ambulatory freedom. The system also includes ports for intravenous access as well as a port for respiratory access. The system may also include a powered air purifying respirator which positively pressurizes the interior space of the system.

A wearable continuous positive airway pressure assembly for protecting a user from breathing airborne particles includes a continuous positive airway pressure machine that has an intake and an exhaust. A pair of shoulder straps is each coupled to the continuous positive airway pressure machine for wearing the continuous positive airway pressure machine on the user's back. An intake hose is fluidly coupled to the intake of the continuous positive airway pressure machine, a filter is fluidly coupled to the intake hose, and an exhaust hose is fluidly coupled to the exhaust of the continuous positive airway pressure machine. A face mask is fluidly coupled to the exhaust hose to receive the pressurized air from the exhaust hose thereby inhibiting the user from breathing ambient air.
