Medical oxygen is an essential medicine in the treatment of COVID-19 and other diseases. Each Doctor, Nurse, Administrator needs to know how to calculate the need of oxygen for a patient in a covid center ward or an ICU. The oxygen requirement is different for Wards, Patients on Ventilator & Patients on BiPAP. Planning the Bed Capacity for Covid Center as per oxygen requirement is needed.

TYPES - 1-Jumbo Oxygen Cylinder = 7000 Litres Oxygen = 7 Cubic Meter
1-Dura Oxygen Cylinder = Contain Nearly 22 Jumbo
1-PORTA (1KL) Oxygen Cylinder = Contain Nearly 100 Jumbo
1-Liter of Liquid Oxygen gives 861 Litres of Gaseous Oxygen
OXYGEN GENERATION PLANT
Patient on Oxygen Mask / Non Rebreathing Mask (NRBM) / Venturi Mask. Considering Maximum Oxygen Flow = 15 Litre/ min For 1-bed = 15(Lit) 60 (Min) = 900 Litres / hour = 900 24(hours) = 21600 Litres / day / bed = 21600 歎 7000 (1 jumbo) = 3 Jumbo oxygen cylinder / day / bed.
Patient on Non Invasive Ventilator ( NIV) Considering Maximum Oxygen Flow = 60 Litre/ min For 1-bed = 60(Lit) 60 (Min) = 3600 Litres / hour = 3600 24(hours) = 86400 Litres / day / bed = 86400 歎 7000 (1 jumbo) = 12 Jumbo oxygen cylinder / day / bed.
For Intubated Patient (Patient on invasive Ventilator) Required oxygen flow considering = 12 Liters/ Min. = 12(Lit) 60 (Min) = 720 Liters / hour = 720 24(hours) = 17280 Liters / day / bed = 17280 歎 7000 (1 jumbo) = 2.5 to 3 Jumbo oxygen cylinder / day / bed.
EXAMPLE For Covid ICU = 35 Beds. Considering that all 35 ICU Beds running with Non Invasive Ventilators. Oxygen Req. of Covid ICU= Oxygen Requirement for 1bed No of beds = 86400 (lit of O2) 35 beds = 3024000 Litres of gaseous O2 = 3024000 歎7000 = 432 Jumbo oxygen cylinder required / day
