Patient Ventilator

 ventilator information including: anesthetic agent, anesthetic agent inspired fraction concentration, respiratory tidal volume, respiratory rate, airway positive inspiratory pressure, inspired fraction of nitrous oxide, and end-tidal fraction of nitrous oxide

PID

Patient ID number which is a unique identifier for an individual patient.

Obs_time

Obs_time is the date and time at which the ventilator measurements were taken.
 

Agent, Agent_Fi, Agent_Et

Agent is the anesthetic agent, Agent_Fi is the anesthetic agent inspired fraction concentration, and Agent_Et is the end-tidal concentration being detected.
 

ETCO2, FICO2, FIO2, ETO2

ETCO2 is the end-tidal carbon dioxide measurement, FICO2 is the inspired fraction of carbon dioxide, FIO2 is the inspired fraction of oxygen, ETO2 is the end-tidal oxygen measurement.  

TV, RR, PEEP, PIP

TV is the respiratory tidal volume, RR is the respiratory rate, PEEP is the airway positive end-expiratory pressure, and PIP is the airway positive inspiratory pressure. 
 

FIN20, ETN20

FIN20 the is inspired fraction of nitrous oxide and ETN20 is the end-tidal fraction of nitrous oxide.
