Mortality rate from mechanical ventilation?

Mortality rate from mechanical ventilation?

Depends: Much depends on the reason for intubation. If done to maintain airway during surgery the rate is almost zero. If done because of an underlying illness which effects pulmonary ventilatory capacity it will depend on the disease, age of patient, underlying issues. ...Read more

What does a fast heart rate on an unconscious victim mean?

Too broad: It can mean many things. Sepsis, shock from bleeding, pulmonary embolus etc. Need to have more info than just tachycardia. ...Read more

Will an internal defibrillator keep on shocking the heart when the patient dies?

No: Most defibrillators will stop after 10-15 shocks. Also, death occurs from asystole so a defibrillator would eventually sense that and try to pace but not shock. ...Read more

What does transcutaneos cardiac pacing mean?

What does transcutaneos cardiac pacing mean?

RHYTHYM Support: Pacing and pacemakers have been with us decades now. For individuals with low pulse/ heart block a fib etc symptoms of syncope or death can occur. Electrical wires can be placed onto skin surface or surgically to the heart surfaces. These are tested for best thresholds, and attached to selected pacemaker/aicd or device with battery to send stimulus to the heart. ...Read more

What cells in the heart can generate electrical impulses on their own?

What cells in the heart can generate electrical impulses on their own?

All of them: Any tissue can do this, technically. The order of impulse formation is generally: sa node > atrium > proximal his tissues > av node > ventricles > purkinje fibers. But it can vary from person to person. ...Read more

How does valsalva maneuver slow the heart rate down? What's the mechanism?

How does valsalva maneuver slow the heart rate down? What's the mechanism?

The valsalva does: not slow the heart rate. It increases the heart rate during the time of increase in intrathoracic pressure due to restricted venous return. Wikipedia has a nice and easy to understand description: https://en.wikipedia.org/wiki/Valsalva_maneuver. If you mean slowing or breaking an episode of SVT it is from compensatory increased vagal tone. ...Read more

Does pacemaker beep or signal patient when dying?

Does pacemaker beep or signal patient when dying?

Yes it does.: Often this means you he reached ERI of the pacemaker. It needs to be interrogated immediately. ...Read more

Why is asystole (i.e. flatline) a non-shockable heart rhythm?

Why is asystole (i.e. flatline) a non-shockable heart rhythm?

No rhythm to reset: Shocking the heart resets the electrical system of the heart. In asystole, there is no electrical activity to reset. ...Read more

What causes electrical shock sensation in arm?

What causes electrical shock sensation in arm?

Shocks in arms: Lots of things could cause this, however the most common thing is neck pathology where the nerves travel down from the brain to to arms. If there is any narrowing or pinching of the nerves this could cause it. Be careful with your neck, it holds your head on. See your doctor for other causes that could present this way. ...Read more

Low qrs voltage in limb leads [qrs deflection 0.5 mv in limb leads] atypical ecg.... Healthy 27 years old what does this mean?

Low qrs voltage in limb leads [qrs deflection 0.5 mv in limb leads] atypical ecg.... Healthy 27 years old what does this mean?

Low voltage: Low voltage on an electrocardiogram (ECG) can be a sign of cardiomyopathy (weak heart muscle), pericardial effusion (fluid around the heart), obesity, lung disease. thyroid disease, and others. In most cases you would already know that you have these conditions. It is possible that technical issues with the ECG recording created an error. I would repeat the tracing. Glad to look at it for you. ...Read more

How often does the electric shock revive someone who had a cardiac arrest?

How often does the electric shock revive someone who had a cardiac arrest?

Reset conduction: You heart has an electrical conduction system that controls how the heart muscle contracts. Often in cardiac arrest that conduction system is sending disordered electrical signals. The shock sometimes given during cpr/acls is an attempt to "reset" the conduction system so the electric signals go back to the proper order. ...Read more

Each minute that defibrillator is delayed reduces the chance of survival of a cardiac arrest victim by how much?

Each minute that defibrillator is delayed reduces the chance of survival of a cardiac arrest victim by how much?

Every minute counts: A rhythm which can be converted should be done as soon as possible. After 4minutes a good outcome is unlikely. ...Read more
