Modifying a CPAP or BiPAP machine for passive ventilation (or assisted suicide)
Note, though, one problem with this technique is that the expired breath contains a high virus load. Ejecting this used air into a room, presents a considerable risk to anyone caring for the patient.
Modification of CPAP and BiPAP Machines
The much-reported shortage of expensive active ventilation machines as the global pandemic spreads, has focused attention on the adaptation of the much cheaper CPAP and BiPAP machines to treat those with developing COVID pneumonia. BiPAP machines have been successfully adapted so that a measured volume of pre-humidified and oxygenated air can be delivered at a controlled pressure. If the sealing face mask is abandoned, and replaced by an endotracheal tube, a poor person’s ventilation can be achieved.
