[Verse 1]
Pipeline at fifty PSI comes through the wall,
Cylinders backup when the pressure drops to fall,
Pin index safety keeps the gases in their place,
Oxygen is white, nitrous oxide gets blue face,
Two-thousand PSI inside the E-tank stored,
Oxygen failure trips the alarm, cuts hypoxic cord,
Second source kicks in, the failsafe holds the gate,
No hypoxic mixture makes it past the interlock's weight
[Chorus]
Pipeline, cylinder, flowmeter, vape,
Pin index stops the lethal swap escape,
Oxygen flush at fifty, bypass the flow,
Soda lime absorbing CO2 below,
Check the machine before the patient's under,
Miss a step and you'll be torn asunder
[Verse 2]
Flowmeters read from bottom, bobbin spins and floats,
Variable bypass vaporizer, agent concentration notes,
Desflurane needs a heated pressurized design,
Twenty-three degrees boiling point keeps it out of line,
Tec six vaporizer, electronically controlled,
Injection-type for total vapor, newer stories told,
Interlocks prevent two vaporizers running hot,
One agent at a time is all the circuit's got
[Chorus]
Pipeline, cylinder, flowmeter, vape,
Pin index stops the lethal swap escape,
Oxygen flush at fifty, bypass the flow,
Soda lime absorbing CO2 below,
Check the machine before the patient's under,
Miss a step and you'll be torn asunder
[Verse 3]
Mapleson A is Magill, efficient for the awake,
D and E for pediatric, F for Jackson-Rees sake,
Circle system rebreather, unidirectional valves,
Inspiratory, expiratory, soda lime resolves,
Granules turn from white to violet when they're spent,
Desiccated absorbent brews compound A, COvent,
High flow flushes channel heat, reaction gone compound,
Sevoflurane plus dry soda lime, toxic ground
[Bridge]
Bellows rise on exhalation, piston drives without a bag,
VCV targets volume, PCV rides the pressure tag,
PSV for spontaneous, SIMV bridges both the states,
APL valve limits circuit pressure, sixty centimeters gates,
Scavenging pulls the waste gas out before it fills the air,
Occupational limits, chronic exposure — handle with care
[Chorus]
Pipeline, cylinder, flowmeter, vape,
Pin index stops the lethal swap escape,
Oxygen flush at fifty, bypass the flow,
Soda lime absorbing CO2 below,
Check the machine before the patient's under,
Miss a step and you'll be torn asunder
[Verse 4]
ASA checklist, AAGBI morning ritual,
High pressure, low pressure, leak test habitual,
Flush with oxygen, occlude the Y-piece tight,
Pressure holds or circuit compromise comes to light,
Disconnect alarm triggers when the capnograph flatlines,
Stuck expiratory valve traps breath in dangerous confines,
Wrong agent filled, tipped vaporizer, cross-contamination,
Systematic checkout is your strongest foundation
[Outro]
So trace the gas from wall to lung and back again,
Know your pressures, colors, volumes, valves, and when,
Every bobbin, granule, bellows has a role to play,
The machine that breathes for others needs your full survey
