ClearO2 15L Oxygen Can with Mask and Tube | Pure Breathing Oxygen in a Lightweight Aluminium Canister | Made in Britain (Full Kit, 15 l (Pack of 1))

Product Information

Once the target saturation has been identified and prescribed, guidance regarding the most appropriate delivery system to reach and maintain the prescribed saturation is provided for those administering oxygen. If a patient’s oxygen requirements increase so much that they do not respond to 15L/min via a non-rebreather mask: The mask covers both your nose and mouth. One-way valves prevent exhaled air from reentering the oxygen reservoir. Utilizing a simple face mask sets the meter between 5 and 12 liters. Never keep the meter below 5 liters if you’re using this type of mask. For example, 15 L/min of oxygen at a FiO2 of 100% and 15 L/min of air at a FiO2 of 21% to give a total of 30 L/min of flow at a diluted FiO2 of 60%. Or perhaps 15 L/min of oxygen at a FiO2 of 100% and 30 L/min of air at a FiO2 of 21% to give a total of 45 L/min of flow at a diluted FiO2 of 47%. The world is your oyster!Devices such as the AIRVO 2, do all of the above calculations for you. All you need to do is dial-up how much total flow you want to set for your patient and increase the oxygen flow meter to achieve the desired FiO2 to maintain adequate oxygen saturation.

Ensure the reservoir bag fills by temporarily obstructing the valve before positioning the non-rebreather mask on the patient. A5. Since oxygenation is reduced in the supine position, fully conscious hypoxaemic patients should ideally be allowed to maintain the most upright posture possible (or the most comfortable posture for the patient) unless there are good reasons to immobilise the patient (eg, skeletal or spinal trauma) (grade D). Usually, nursing staff follow a local protocol regarding how frequently to measure observations, including oxygen saturations. Document clear instructions if you wish for it to be measured at a certain frequency.

British Thoracic Society Guideline for oxygen use in adults

All peri-arrest and critically ill patients should be given 100% oxygen (15 l/m reservoir mask) whilst awaiting immediate medical review. Patients with risk factors for hypercapnia who develop critical illness should have the same initial target saturations as other critically ill patients pending the results of urgent blood gas results after which these patients may need controlled oxygen therapy or supported ventilation if there is severe hypoxaemia and/or hypercapnia with respiratory acidosis. Royal Pharmaceutical Society of Great Britain (2005) British National Formulary for Children. London, BMJ Publishing House Ltd Used for emergency situations (Advanced Life Support Group, 1997) due to a large reservoir that allows oxygen only to be breathed in by the child. This prevents the inhalation of mixed gases. The approximate inspired oxygen received is 99% (10). Nasal Cannula is typically started at 2L/min and then titrated upwards to as high as 6L/min, although 2-4L/min is ideal. This delivers 25-40% FIO2, depending upon their respiratory rate, tidal volume, and amount of mouth breathing.The key aim of this guideline is to make oxygen use in emergency and healthcare settings safer, simpler and more effective. Oxygen is probably the commonest drug used in the care of patients who present with medical emergencies. Prior to the publication of the first British Thoracic Society Guideline for Emergency Oxygen Use in Adult Patients in 2008, 1 ambulance teams and emergency department teams were likely to give oxygen to virtually all breathless or seriously ill patients and also to a large number of non-hypoxaemic patients with conditions such as ischaemic heart disease or stroke based on custom and practice. About 34% of UK ambulance journeys in 2007 involved oxygen use. 4 This translated to about two million instances of emergency oxygen use per annum by all UK ambulance services, with further use in patients' homes, GP surgeries and in hospitals. Audits of oxygen use and oxygen prescription have shown consistently poor performance in many countries, and most clinicians who deal with medical emergencies have encountered adverse incidents and occasional deaths due to underuse and overuse of oxygen. 5–11 Oxygen should be titrated up or down by trained nursing staff as shown on flow chart to maintain oxygen saturations in target range. Come in three sizes: 250 mls, 500 mls and 1500 mls. The smallest one is ineffective even at birth. Two smallest bags have a pressure-limiting valve set at 4.41 kPa (45 cm H 20) to protect the lungs from barotrauma (Damage caused to tissues by a change in pressure inside and outside the body). The reservoir bag enables the delivery of oxygen concentrations up to 98%. Without the reservoir bag it is not possible to supply more than 50% oxygen
