Ventilation and oxygenation Piotr Szwedziński 1 BVM (Bag Valve Mask) components 2  Wentilation An adult person should be ventilated at a rate of 10 to 12 breaths per minute (breath every 5 to 6 seconds) 3  Oxygenation Oxygen can be administered to the injured person passively or actively Passive oxygen therapy - a breathing mixture containing oxygen is inhaled independently through an oxygen mask with a reservoir or a nasal catheter. Active oxygen therapy - a breathing mixture containing oxygen is forced through a self- inflating bag with a reservoir. Active oxygen therapy should be used in the absence of breathing or when the number of breaths is < 10 and > 30 4  Oxygenation Oxygen should be administered at a flow of 12-15 liters per minute How to calculate the amount of oxygen in the cylinder and how long it will last? pressure x capacity (multiply), we divide the result by the flow in liters per minute and we get the result for how many minutes we will have enough oxygen 5  Example 200 atm x 2,7 l = 540 540/ 15l/min = 36 36 minutes 120 atm x 2 l = 240 240/ 12l/min = 20 20 minutes 6 Thank you for your attention 7
