Prosthetic heart

Prosthetic heart

A heart prosthesis. It contains an electric motor that pumps blood smoothly around the body. Users often report feeling tired, but it's better than the alternative.

The Prosthetic heart is a heart replacement with 80% efficiency. It affects Blood pumping and several dependent stats - due to its below-normal part efficiency it negatively affects healthy pawns but may benefit injured or unhealthy ones.

Acquisition

Prosthetic hearts can be crafted at a Machining table once the Prosthetics research project has been completed. They require Steel 25 Steel, Component 4 Components, 15,000 ticks (4.17 mins) of work, and a Crafting skill of 5.

Summary

Prosthetic hearts have an 80% part efficiency, or a -20% reduction compared to a healthy organic heart. Installing it thus results in a 20% loss to Blood Pumping, which results in a Move Speed reduction of 7.5% (equal to a prosthetic leg) and a 4% reduction in Consciousness, Manipulation, Talking, and Eating. Additionally, they require 6% more rest due to the 94% Rest Rate Multiplier. Finally, this also results in a 20.3% reduction in an otherwise healthy pawn's market value.

However, installing a prosthetic heart will instantly cure any artery blockages, and prevent heart attacks from any source, including drugs. Installing a prosthetic heart in a patient with a healthy natural heart will result in the heart being harvested for later use. Normal organ harvesting penalties apply when harvesting a heart in this way.[Fact Check]

Installation

Installing the part requires 2,500 ticks (41.67 secs) of work, ?x medicine of ?? quality or better, and a Medical skill of 4.

Removing the part requires ? of work, ?x medicine of ?? quality or better, and a Medical skill of ?.

If the operation fails, the part has a chance[What Chance?] to be destroyed. If the installation surgery fails, there is also a 25% chance that the patient dies. Thus, as the maximum success chance of any surgery is capped at 98%, there is always at least a 0.5% chance of death per attempt.

Analysis

Prosthetic hearts can be important tools to prevent heart attack deaths in the early game, should an otherwise valuable colonist be prone to them. Its small but significant stat penalties mean that, ideally, natural hearts or bionic hearts should be used instead. Bionic hearts in particular have the same disease immunities, but improve rather than lower stats.

An artifical heart could be used to make the use of wake-up safer in the long term, which could otherwise cause heart attacks. However, wake-up isn't free to make, and you'll lose productivity outside of drug use. This option should be weighed against a circadian half-cyclerContent added by the Royalty DLC, which is a one time cost with a a flat -15% Consciousness penalty.

On the plus side, prosthetic hearts provide a fairly cheap method of harvesting an ordinary heart. This way, you can get an organic heart without killing a prisoner, or obtain both a heart and a liver; just remember to harvest the liver last, as organs can't be retrieved from a corpse. Doing this on an allied/neutral pawn will cause a -20 penalty to goodwill with the faction, for an "unnecessary surgery".

While it does provide a buff to pawns with the Body modder trait, its negative effects on healthy pawns means it should be passed over for other, less detrimental prostheses.
