Question

among its other purposes, how is the valsalva maneuver used? multiple choice to clear carbon monoxide from the body and replace it with oxygen as part of the procedure for giving cpr to a person in respiratory arrest to expel more than the usual tidal volume from the lungs to ventilate the lungs during eupnea to aid in defecation and urination

Answer 1

The Valsalva maneuver is a voluntary technique involving the contraction of specific muscles to increase intra-abdominal pressure. It has multiple purposes, including aiding in defecation and urination and assisting in the recruitment process of opening airways. It is not used to clear carbon monoxide or replace it with oxygen in CPR procedures.

Step-by-step explanation:

The Valsalva maneuver is a voluntary technique that involves contracting the diaphragm and abdominal muscles while closing the glottis, resulting in increased intra-abdominal pressure. It has several purposes, including aiding in defecation and urination, as well as assisting in the recruitment process of opening airways that normally remain closed when there is an increase in cardiac output. However, it is not used to clear carbon monoxide from the body or to replace it with oxygen in CPR procedures.

Answer 2

The Valsalva maneuver is used to expel more than the usual tidal volume from the lungs. So the answer is the second option.

The Valsalva maneuver is a forceful attempt to exhale against a closed airway, which can increase pressure in the chest and abdomen. This pressure can help to clear mucus from the airways, aid in defecation and urination, and push hernias back into place and can also be used to clear carbon monoxide from the body and replace it with oxygen, but this is not a typical use of the maneuver.

The Valsalva maneuver is performed by closing the mouth and pinching the nose shut while forcefully trying to exhale. This creates a pressure differential between the lungs and the external environment.
