peer agreement (net): +1intrathoracic pressure Explanation: It is the only thing that makes sense to me, after all the research! Cheers! http://www.ncbi.nlm.nih.gov/books/NBK402/ -------------------------------------------------- Note added at 1 hr (2013-09-25 09:49:31 GMT) -------------------------------------------------- he physiologic response to the Valsalva maneuver has been divided into four phases. In the first phase, blood pressure increases slightly due to increased intrathoracic pressure. As forced expiration is continued, mean arterial pressure and pulse pressure decrease. During the second phase, heart rate begins to increase. The third phase begins with release of the forced expiration and consists of a further drop in blood pressure due to a sudden drop in intrathoracic pressure, and the heart rate increase is sustained or may accelerate even more. |

peer agreement (net): +2surrounding the heart and aorta Explanation: "pressure surrounding the heart and aorta" (peri = around) I am not aware of a one-word term for this in English. |

If I were you, I would find a good medical site on this manoeuvre in English and take it from there. -------------------------------------------------- Note added at 27 mins (2013-09-25 09:09:32 GMT) -------------------------------------------------- see http://books.google.co.uk/books?id=6zJoAYx0j5QC&pg=PA486&lpg... -------------------------------------------------- Note added at 30 mins (2013-09-25 09:11:55 GMT) -------------------------------------------------- http://www.ld99.com/reference/old/text/2878909-407.html Phase 3 (Release of straining) BP decreases because (essentially reverse of phase 1) Transient decrease in return of blood due to removal of the squeeze on intrapulmonary vessels Removal of pressure on aorta HR increased further [PK1:p157] HR unchanged because the phase is very brief [KB2:p53] -------------------------------------------------- Note added at 31 mins (2013-09-25 09:13:15 GMT) -------------------------------------------------- http://www.coheadquarters.com/PennLibr/MyPhysiology/Mod20/de... Phase III of the Valsalva maneuver occurs after the glottis or mouth is opened and the first breath is taken. Blood surges into the right heart, fills the expanding lung vasculature, but return to the left heart is slow. Consequently, left ventricle stroke volume remains low and systemic hypotension continues. Only when normal breathing resumes, in Phase IV, do blood pressure and heart rate renormalize. During this period, arterial pulse pressure becomes very wide, indicative of the large stroke volume resulting from the supra-normal left ventricular filling which occurs as pent-up venous blood returns to the heart. Fainting (syncope) due to cerebral ischemia may occur during Phases II or III, when hypotension is most extreme. The Valsalva maneuver should be attempted with caution in persons with coronary artery disease. -------------------------------------------------- Note added at 33 mins (2013-09-25 09:15:17 GMT) -------------------------------------------------- I am unable to find anything with "peri-aortic" in relation to phase III. -------------------------------------------------- Note added at 48 mins (2013-09-25 09:30:31 GMT) -------------------------------------------------- p.s. the only finding in relation to this is the mention of intrathoracic blood pressure, not the aorta or heart. |
