This will normalize once. treatment pressure is achieved. Depending upon the treatment pressure used for. your therapy, you might be instructed to peri-. odically breathe air from a facemask inside the. chamber. This provides an additional protection. against oxygen toxicity.
When to See a Doctor. If you have frequent bouts of chest pain, heart palpitations or irregular heartbeats, shortness of breath or fainting, you should see your doctor right away as sudden cardiac arrest requires emergency treatment. If these symptoms are ongoing, call 9-1-1 immediately.ââ.
A cardiac arrest is different from (but may be caused by) a myocardial infarction (also known as a heart attack), where blood flow to the muscle of the heart is impaired. It is different from congestive heart failure, where circulation is substandard, but the heart is still pumping sufficient blood to sustain life.nexpected cardiac arrest can lead to death within minutes: this is called sudden cardiac death (SCD). The treatment for cardiac arrest is immediate defibrillation if a shockable rhythm is present, while cardiopulmonary resuscitation (CPR) is used to provide circulatory support and/or to induce a shockable rhythm.
