Bag valve masks

Bag valve masks for manual ventilation. The range covers Laerdal's disposable The BAG II in five mask sizes and the reusable silicone resuscitators.

The choice is first between disposable and reusable, then between mask sizes. The disposable removes cleaning and cross-contamination; the silicone bag withstands autoclaving and holds up to repeated use.

The BAG II — disposable, five sizes

The range is divided by patient weight rather than age. No. 1 and no. 2 are for infants of 2.5–12 kg, where no. 1 has the smallest mask diameter in the range. No. 3 is sized for children of 10–20 kg. No. 4 and no. 5 are for adults above 20 kg, with no. 5 carrying the largest mask for larger facial anatomy. No. 4 is also available in a pack of 12 for services that use several a year.

The construction is the same throughout. The joint between mask and bag rotates through 360 degrees, so your working position stays free regardless of where you stand relative to the patient. The yellow bladder gives tactile feedback on lung response, which is what helps against over-ventilation. The mask is transparent, so lip colour, secretions and exhalation misting can be followed during ventilation.

The paediatric versions, no. 1–3, carry a pressure relief valve at 35 mm H₂O protecting small lungs against excessive pressure. The adult versions instead have an adjustable hand strap that reduces physical effort during prolonged ventilation.

The silicone bags can be sterilised

Adult Resuscitator Complete is supplied with mask, reservoir bag and tubing — ready for immediate use on patients above 20 kg. Adult Basic is the same bag without mask and accessories, for anyone who already has masks or prefers to choose them separately. Both withstand autoclaving and dishwashing.

The connector is a standard 15/22 mm throughout the range, so the bags fit existing masks and ventilation equipment. If you only need a mask, the Laerdal Silicone Mask no. 4–5+ covers adults. Other airway equipment is under airway and breathing, and Laerdal's full range under Laerdal.

Frequently asked questions about bag valve masks

What is a bag valve mask?

A manual resuscitator used to ventilate a patient who is not breathing adequately on their own. In Scandinavia it is often called a *Rubens blåsa* after the Danish anaesthetist Henning Ruben. The device and the term refer to the same thing.

Which size should I choose?

Size follows patient weight. No. 1 and 2 for infants of 2.5–12 kg, no. 3 for children of 10–20 kg, no. 4 and 5 for adults above 20 kg. The difference between 1 and 2, and between 4 and 5, is mask diameter — choose by face size within the correct weight class.

Disposable or reusable?

The disposable The BAG II removes cleaning and any risk of cross-contamination, which suits ambulances, response bags and preparedness stores. The silicone bag withstands autoclaving and dishwashing and works out cheaper per use in services that ventilate often and have a cleaning routine in place.

Why do the paediatric bags have a pressure relief valve?

The valve opens at 35 mm H₂O and protects small lungs against excessive ventilation pressure. It is fitted on no. 1, 2 and 3. The adult models omit it because pressure there is governed by the shape of the bag and the operator's feel for lung resistance.

What is included in Complete compared with Basic?

Complete is supplied with mask, reservoir bag, tubing and the remaining components needed for immediate use. Basic is the same silicone bag without mask or accessories, intended for anyone who already has masks or wants to assemble their own set.
