### Discovery

This particular APV-0730800-U was found in ARP 074, which is an anomalous set of tunnels underneath a massive hospital complex called St Alice North.

This is a *APV-0730800-U* , a medical machine manufactured by a company called NexTe Research. An APV-0730800-U is a part of a line of positive pressure ventilators but interestingly, this version is designed specifically for use in underground hospitals and institutions, indicated by the U. Differences between normal versions and models designed for use underground include a difference in the size of the unit. Most of the usual models are roughly 125.7 cm tall and 65 cm wide. The underground models are probably about 100 cm tall and 40cm wide, thus being more compact. Both models have the same functions and features, although the underground models also have an internal oxygen tank as well as internal batteries. Due to their compact nature, underground models are slightly noisier.

Both ventilators can do A/C, SPONT and SIMV modes as well as all other modern ventilator features. However, underground models also have two new features. Firstly, U models are hard to accidentally turn off. There's a whole procedure to shut them down, involving switching 3 switches underneath a cover on the back. If any of these switches are flipped, the machine lets out a constant beep before its turned off to indicate to others nearby that someone is trying to turn it off. After flipping all of the switches, the user must then go through its menu to select shutdown. Secondly, the U models have maintenance in mind with fix-ability taken to heart. Each of their internal components swing out on either hinges or come out on rails, allowing for maintenance access in a smaller space and maintenance access to a particular component without removing other components in the way.

Both models use a cathode ray tube to display its menus, wave-forms, graphs, settings and info. Some other models in the line use a LCD screen where available but due to severe shortages in the required minerals, this isn't always the case. Because of this, almost all medical machines from NexTe Research can in fact use either a cathode ray tube module or LCD module. Both models are also powered by a LP-75000 micro-computer, the same computer often used in other medical equipment [1].

This particular APV-0730800-U was found in ARP 074, which is an anomalous set of tunnels underneath a massive hospital complex called St Alice North. ARP stands for Anomalous Research Project and each ARP is guarded closely by the Civilian Research Foundation, sort of similar to the SCP foundation. ARP 074 seems to consist of the old underground hospital sections which apparently used mostly older medical equipment such as equipment from NexTe Research before the company suddenly went out of business. The CRF discovered ARP 074 when staff working in the basement levels of St Alice North rediscovered the tunnels and two people went missing, resulting in a general consensus that those tunnels are either “haunted” or “cursed”. Initial investigations conducted by the CRF did indeed discover unusual activity and dangerous unknown entities down there which prompted the CRF to quickly construct 5 large reinforced vault doors, sealing off ARP 074 from the rest of the world. Recently, the CRF sent a team to properly explore ARP 074, discovering this particular ventilator and something else……

*[1, The LP-75000 series is based on a 32-bit architecture specifically designed for real-time applications and safety critical uses such as medical, spanning all the way up to miniature nuclear core regulation and management. Unusually, there are a few home computers that use the same architecture. An interesting fact about the LP-75000 series is that, development tools, including the LP-7505 development kit, are freely available for borrowed use from LP for any LP-75000 system owner if that would be a home owner, manufacturer or other organisation. There is also a big discount for development tools if a LP-75000-owner wanted to buy them.]*
