Mr. Rodriguez is noted to have a reduced inspiratory and vital capacity.
A. On the Bird IPPB machine, which control(s) could be adjusted to increase the volume achieved during therapy? System pressure and flow rate.
B. How would you adjust the setting of these control(s) for this purpose?

C. If the Bennette machine is used what controls can be adjusted to increase the volume? How would the controls be adjusted?

Expert Solution

A. Intermittent positive pressure breathing or IPPB is used for this patient ,this machine is a ventilatory apparatus in which the compressed gas is delivered under positive pressure into patient's airway until a preset pressure is reached. Passive exhalation is allowed through a valve. For this patient ,nebulizing medication is prescribed and also specific pressure and volume amounts are adjusted in the machine.The patient stimulates inspiration,with positive pressure support,and followed by airway pressure returning to atmospheric pressure with passive expiration.

B. Flow and pressure will need subsequent adjustments to patient's needs and goal. The therapy is volume oriented.Therapists would set up the machines by dialing appropriate sensitivity,flow and pressure levels.The flow level determines how much pressure was given to patient.Sensitivity determines how hard the patient had to work to trigger a breath.A circuit was then connected to mask and a nebulized medicine is added to the circuit via nebulizer cup which is connected to a flowmeter via oxygen tubing.

C. If Bennette machine is used a mask is connected to patient, which is connected with a valve to a cylinder of compressed air is used.This device supplies controlled respiration with positive pressure to patient and also this device was not controlled by electricity, so it is not danger for the patient.

What morphometric factors would/could affect vital capacity? If vital capacity was reduced, but tidal volume remained the same for an individual, how would it affect them? Would they notice at rest? If not, why not, and when might they notice the VC reduction? Can I get some help with these questions?

Does our cognitive capacity change as we age? Researchers have noted a change in cognitive functioning as people age (Bartus, 1990). However, the results from other research suggests that the antioxidants in foods such as blueberries may reduce and even reverse these age-related declines. You decide to conduct your own study using a related-samples (within-subjects) design, to determine if a blueberry supplement can change cognitive capacity in older adults. You will use an alpha level = .05, and choose to...
