4,24,41) It is said that IH, intrathoracic pressure changes and arousals by OSA trigger consecutive mechanisms that might result in endothelial dysfunction and arterial diseases.
The valve closes in the decompression phase of CPR, temporarily blocking the more than necessary passage of passive air through the open airway into the patient's lungs, thus decreasing intrathoracic pressure and creating a small vacuum.
1,6) IJV phlebectasias must be differentiated from other neck masses that enlarge with increased intrathoracic pressure.
The mechanism for developing SPM is based on the Macklin effect, consisting of increased intra-alveolar pressure due to an increase in intrathoracic pressure, causing the rupture of the peripheral pulmonary alveoli.
7,8] Causative factors of SPM are less clear although some of the trigger factors such as asthma attack, barotrauma, intrathoracic pressure increase, valsalva maneuver, and withdrawal symptoms of illicit drugs are known.
IOP may be influenced by several factors related to anaesthesia, including changes in the blood and intrathoracic pressure, some anaesthetic drugs like ketamine and depolarising muscle relaxants, hypoventilation, hypercapnia, drugs affecting the sympathetic and parasympathetic systems such as atropine, epinephrine, trendelenburg position and laryngoscopy.
The ResQCPR System uses Intrathoracic Pressure Regulation (IPR), a proprietary, non-invasive therapy developed by Advanced Circulatory Systems, Inc.
The company's novel Intrathoracic Pressure Regulation therapy platform has implications for multiple medical conditions, Zoll said.
There are many factors affecting the value of CVP, such as cardiac performance, blood volume, vascular tone, increased intra-abdominal or intrathoracic pressure and vasopressor therapy.
In previous studies the superimposition of an elevated intrathoracic pressure caused by a valsalva maneuver has been reported to contribute to an increased RPP [15].
Increased intrathoracic pressure decreases venous return, which may impair cerebral perfusion pressure, particularly in hypovolemic patients.
