You are managing an rosc patient. while transitioning the patient to the ambulance, your partner dropped and broke the pulse oximeter. during transport, how much oxygen should be provided?

I think an amount of 15 lpm, would be appropriate. Return of spontaneous circulation (ROSC) is resumption of sustained perfusing cardiac activity associated with significant respiratory effort after cardiac arrest. Signs of ROSC include breathing, coughing, or movement and a palpable pulse or a measurable blood pressure. 

Nimbostratus is the correct answer.
explanation: nimbostratus clouds are the type of clouds that are mostly likely present on gray, rainy day. these clouds produce continuous rain, snow and there is no thundering or lightening either.
