'''Lungs''' are harvestable [[human]] organs that allow a pawn to [[Breathing|breathe]].

== Acquisition ==
{{see also|Human resources#Organ harvesting{{!}}Human resources}}
The lung item can be harvested from live [[human]]s through [[surgery]]. The lung must be perfectly healthy in order to obtain the item. This bill requires 1 of any type of medicine to perform. [[Doctoring#Success_chance|Success chance]] is dependent on a number of factors, including bed [[quality]], [[Room stats|room cleanliness]], and doctor skill - specifically the doctor's [[Medical Surgery Success Chance]]. Lungs can be directly harvested, but installing a [[detoxifier lung]] {{BiotechIcon}} will also net an organic lung. Removing both lungs will kill the pawn.

Removing a healthy lung from a guest or prisoner will decrease faction [[goodwill]] by 80 points, down to the cap of -100. Removing any organ from anyone depresses the "donor" with -30 [[mood]] penalty for 7 days and 7 hours. Other colony members can gain potentially tremendous [[mood]] penalties, which all stack:
: {{--|5}} for "Someone's organ harvested" (any organ); {{--|6}} if colonist was harvested
: {{--|6}} for "Someone organ-murdered" (if fatal)
: {{--|5}} for "Witnessed ally's death" (if fatal and on colonist)
: {{--|4}} for "Observed Corpse" (if fatal)
Pawns with the [[Bloodlust]] or [[Psychopath]] traits, or those with an [[Ideoligion]] with [[Ideoligion#Organ use|Organ Use: Acceptable]]{{IdeologyIcon}} are not affected by the harvesting of other people. Other Ideologion precepts may change moodlets for harvest and organ use.

Lungs can also be acquired through [[trading]] with faction settlements or Exotic Goods traders.

== Summary ==
A pawn requires 1 lung to live. Each lung contributes towards 50% of a pawn's [[Breathing]], so losing a lung results in 50% Breathing. Breathing itself affects [[Consciousness]], [[Moving]], and the [[Rest Rate Multiplier]]. A completely removed lung would result in -10% Consciousness, -15% to sleep efficiency, and -20% Moving; Consciousness also reduces a variety of other stats. 

The tissue of the lungs can be affected by [[asthma]], commonly related to age, [[Smokeleaf|smoking]], or exposure to harmful substances. 

=== Installation ===
Installing the part requires {{ticks|2500}} of work, 2x medicine of [[Herbal medicine|herbal]] quality or better, and a [[Skills#Medical|Medical skill]] of 5.

Removing the part requires {{ticks|2000}} of work, 1x medicine of [[Herbal medicine|herbal]] quality or better, and has no [[Skills#Medical|Medical skill]] requirements.

If the operation fails, the part has a chance{{Check Tag|What Chance?}} to be destroyed.

== Analysis ==
{{Rewrite|section=1|reason=Account for new [[detoxifier lung]]}}
Lungs contribute a substantial amount to a pawn's effectiveness. If one is destroyed, you should aim to replace it as quickly as possible. This can be achieved with either another lung (harvested or traded), a [[Detoxifier lung]]{{BiotechIcon}}, or a [[Fleshmass lung]]{{AnomalyIcon}}.

Asthma and permanent injury are less pressing concerns, but are often worth the penalty for organ harvesting. Harvest a lung from a prisoner, or alternatively a guest or worthless colonist (before abandoning them). Non-natural replacements are immune to Asthma and permanent injury, so may also be considered.

{{Breathing Part Efficiency Table}}

A lung is worth {{icon Small|silver||{{Q|Lung|Market Value Base}}}}, as opposed to a [[kidney]]'s {{icon Small|silver||{{Q|Kidney|Market Value Base}}}}. Lungs also reduce pawn capacity much more than a [[kidney]]. A lost kidney reduces Consciousness by 5% and [[Immunity Gain Speed]] by 25%. 

While worth less than a [[heart]] or [[liver]], a pawn can live with 1 lung and 1 kidney harvested. If the mood penalties don't concern you (or don't exist due to [[Ideoligion]]{{IdeologyIcon}}), you can harvest 1 lung, 1 kidney, and 1 heart/liver before you kill a pawn. If you harvest a lung and kidney, you can then donate the prisoner to a [[royal tribute collector]]{{RoyaltyIcon}} for the same amount of [[honor]] as a healthy pawn. Alternatively, if the pawn has the [[Deathless]]{{BiotechIcon}} gene, you can harvest both lungs, both kidney, heart, and liver at the cost of leaving said pawn permanently bedridden.

===Compared to Detoxifier Lung===
[[Detoxifier lung]]s{{BiotechIcon}} are lung replacements that are crafted at fabrication benches after the [[Research#Toxin_filtration|Toxin filtration]] research project has been completed. Each detoxifier lung requires {{Required Resources|detoxifier lung}}. Installing a detoxifier lung replaces that respective lung; if the lung is in perfect condition, it is also harvested without penalty.

Detoxifier lungs have a part efficiency of {{good|110%}}, and grant {{+|60%}} [[toxic environment resistance]] per installed detoxifier lung up to {{+|100%}}. It's also immune to [[Asthma]].

=== Compared to Fleshmass Lung ===
{{Anomaly|section=1}}
[[Fleshmass lung]]s are lung replacements introduced by [[Anomaly]] and can not be crafted. It has no associated item and cost no resources.

Fleshmass lungs have a part efficiency of '''100%''', grant {{+|30%}} [[toxic environment resistance]] per installed fleshmass lung, and generate {{bad|+6%}} pain. It's also immune to [[Lung rot]] and [[Asthma]].
