Safe and easy lung cleansing apparatus and method comprising a hollow nasopharyngeal tube with longitudinal misting and air sections inserted in user's nostril, misting means, lung cleansing fluid, fluid and air pumps and automated postural lung cleansing and drainage bed synchronized with the air and fluid pumps, to rotate and turn the user to mist, drain and thereby in turn all areas of the user's lungs. Some embodiments include a cuirass-type negative pressure ventilator to recruit more alveoli for cleansing, loosen mucus in the lungs and induce a cough to clear mucus. The method may include premedication to loosen mucus, tar and other foreign matter in the lungs. In some embodiments, the user's chest could be vibrated to loosen mucus in the lungs to aid thorough cleansing by the misting and automate postural drainage thereafter.

An adjustable respirator shell, suitable for being worn on a human body trunk, includes a body, a belt and a buffer. The body includes a protrusive portion and a contact portion. The protrusive portion has an opening connecting a fluid pressure controller, and the contact portion is to contact the human body trunk. The belt, connecting the body, is to surround the human body trunk so as to fasten the adjustable respirator shell on the human body trunk. The buffer covers a circumference of the contact portion, and the contact portion contacts the human body trunk via the buffer. In addition, the buffer includes at least one cushion.

An exemplary example of a medical device can include a retention structure for at least partially encircling a patient's body, the retention structure including a central member and a support portion configured to be placed underneath a patient, a piston extending from the central member, a driver coupled to the piston configured to retract and extend the piston, a patient contact member attached to the piston, the patient contact member configured to adhere to the patient's body, and a controller. The controller can be configured to cause the driver during a session to perform at least two cycles of negative pressure ventilation, each of the at least two cycles of negative pressure ventilation including positioning the piston at a reference position, retracting the piston from the reference position to an expansion position to expand a chest of a patient to generate negative pressure ventilation, and returning the piston from the expansion position to the reference position.

Systems and methods related to the field of cardiac resuscitation, and in particular to devices for assisting rescuers in performing cardio-pulmonary resuscitation (CPR) are described herein. The system includes an applicator device configured to provide ACD CPR treatment to a patient's chest according to a plurality of phases at least one sensor configured to be coupled to the patient's chest and to measure at least one parameter related to the ACD CPR treatment and information for determining whether at least one transition point of the ACD CPR treatment has been reached; and one or more processors configured to provide a feedback signal based on a parameter for administering ACD CPR treatment to the patient's chest according to a desired treatment protocol.

A system includes a guidance device that provides feedback to a user to compress a patient's chest at a rate of between about 90 and 110 compressions per minute and at a depth of between about 4.5 centimeters to about 6 centimeters. The system includes a pressure regulation system having a pressure-responsive valve that is configured to be coupled to a patient's airway. The pressure-responsive valve is configured to remain closed during successive chest compressions in order to permit removal at least about 200 ml from the lungs in order to lower intracranial pressure to improve survival with favorable neurological function. The pressure-responsive valve is configured to remain closed until the negative pressure within the patient's airway reaches about 7 cm H.sub.2O, at which time the pressure-responsive valve is configured to open to provide respiratory gases to flow to the lungs through the pressure-responsive valve.

This disclosure relates to device for providing continuous negative abdominal pressure (CNAP) which selectively recruits (inflates) the dorsal (spinal region) collapsed areas of the lung, while enabling the patient to remain in the supine (usual) position. The CNAP device includes a rigid frame configured to have a shape and size to envelop a patient's lower chest and abdominal area while in a supine position with the frame having opposed edges which sit on a surface on which the supine patient is resting. A series of panels are mounted in the frame such that the series of panels extend around the patient's lower chest and abdominal area. A flexible sheet wrapped around the outside of the panels and is long enough to extend up to the patient's upper chest and down to the patients thighs and wide enough to envelop the supine patient's lower chest and abdominal area. Sealing members are to seal the flexible sheet over the frame and panels and around the patient's lower chest and pelvis, wherein a chamber is formed between the patient and said device when the patient is enveloped by the device. An air inlet coupling extends through one of the panels and is attachable to a suction source which is configured to generate negative pressure of between about 5 to about 10 cm H.sub.2O inside the chamber.

A pressure sensor is mounted to the frame for measuring a pressure inside the chamber and is connected to a display for displaying the pressure inside the chamber. An active pressure controller is connected to the pressure sensor, and a vacuum pump is in flow communication with inside the chamber and connected to the active pressure controller. The device includes a top up pump in flow communication with inside the chamber and connected to the active pressure controller which is programmed to instruct the vacuum pump to provide negative pressure in the chamber to start decompressing the chamber, and to instruct the top up pump to maintain the negative pressure in the chamber.
