Indications for mechanical ventilation at home include respiratory disoreders such as BPD, control of breathing disorders such as central apnea, and neomuscular disorders such as muscular dystrophy. Most children who require long-term ventilation will undergo tracheotomy. Non-invasive ventilation is mostlu used for nocturnal ventilation. The majority of ventilatiors used at home are volume-cycled machines, which deliver a set tidal volume. Many machines are microprocessor controlled and can be used with a wheelchair.
It is important that back-up systems are available. This includes a means of applying bag ventilation and usually a backup ventilator in case the first one fails. Various power sources are available for the primary system. These include standard AC power, back-up rechargeable battery, and additional battery power which may include an automotive-type battery.
