Master Oxygen Delivery Systems with Picmonic

Simple face mask can deliver an FiO2 of 40% to 60% oxygen with a flow of 6 to 12L/min. It can be used in patients that are in mild respiratory distress. If a simple mask has a reservoir bag on it, it is called a partial rebreather mask. Partial rebreather masks deliver an FiO2 of 50% to 60%.

This mask has a valve on the exhalation port and between the reservoir bag and mask. The valves prevent room air from coming into the system. This method delivers an FiO2 up to 95% at 8-15L/min. Make sure that the reservoir remains at least ½ full on inspirations.

Venturi Mask allows providers to set a specific FiO2 to be delivered to the patient. Venturi masks have, what is called, an air entrainer that allows oxygen to be mixed with the room air. This can deliver a precise FiO2 to the patient ranging from 24% to 60%.

Make sure your agency has proper signs hanging, informing visitors of the risk of having an open flame. Instruct people not to smoke near areas where oxygen is in use.

Oxygen is a highly combustible gas that can cause an explosion in certain situations. Make sure that the bag valve mask is removed from the bedside before a shock is delivered during resuscitation efforts.

Educate patients not to smoke when using oxygen and to stay away from open flames. Oxygen is very combustible when introduced to an open flame.

Oxygen can dry out mucosal membranes. If patients will be on oxygen for an extended time or high concentrations will be given, a humidifier should be introduced into the system to help decrease airway irritation.

Skin breakdown can occur around the ears and in the nostril (nasal cannula use). It is important to assess for skin breakdown while performing a daily assessment. Gauze can be wrapped around the tube or strap to decrease pressure and irritation.

Teach the patient to monitor their oxygen tank level at home and when to notify the agency for a refill. It is important to avoid an extra long oxygen tube, because this can be a tripping hazard for the patient and others. Also educate the patient on how to secure the oxygen cylinder and to always have it in an appropriate holder.
