1. ? First level alarm (red): If the condition changes, immediate treatment is required.
2. Secondary alarm (yellow): relatively can be suspended.
3. Technical alarm: check whether the parameters are set reasonably.
Two, the limit of the alarm generated by the mechanism is to set the alarm limit on the parameters, when the monitoring value reaches the set limit or exceeds the limit of a certain period of time will be alarmed. This concept is helpful in discovering that a particular parameter exceeds the physiologic limit, however, a particular parameter does not reflect the overall condition of the patient.
And the normal range of variation of a parameter in a physiologic situation is inherently wide. In addition to arrhythmia, heart rate, respiration, blood pressure, oxygen saturation alarms are limit alarms. The principles of alarm setting of the monitor include:?
Heart rate is 30% above and below your own heart rate. Blood pressure is set according to the doctor's orders, the patient's condition and the base blood pressure. Oxygen saturation is set according to the patient's condition (COPD patients, ARDS patients, and patients with common lung infections).
The alarm volume must be set so that the nurse can hear it within working distance.
5 The alarm range should be adjusted at any time according to the situation.
Indications:
Because ordinary electrocardiograms can only record the electrocardiographic activity of a certain period of time in a short period of time, they are of limited value. The cardiac monitoring system can continuously observe and analyze the electrical activity of the heart in real time, which can be said to be a very valuable means of monitoring the condition of cardiovascular disease.
1. Cardiopulmonary resuscitation (CPR): cardiac monitoring during CPR can help to analyze the cause of cardiac arrest and guide treatment (e.g., defibrillation, etc.); monitoring of the surface electrocardiogram can detect rhythm disorders in a timely manner; after the resuscitation is successful, changes in the cardiac rhythm and rate of the heart should be monitored until it is stabilized.
2. Patients at high risk for heart rhythm disorders: many diseases can have fatal heart rhythm disorders during disease progression. Cardiac monitoring is an important method of detecting serious rhythm disturbances, preventing sudden death, and guiding treatment.
3. Critical cardiac monitoring: acute myocardial infarction, myocarditis, cardiomyopathy, heart failure, cardiogenic shock, severe infections, pre-excitation syndrome and after cardiac surgery. Cardiac monitoring should also be performed in patients who have received certain drugs that are cardiotoxic or affect the cardiac conduction system.
In addition, various critical illnesses are accompanied by hypoxia, electrolyte and acid-base balance imbalance (especially potassium, sodium, calcium, magnesium), and multi-system organ failure.
4. Certain diagnostic and therapeutic operations: such as endotracheal intubation, cardiac catheterization, and pericardial puncture, all of which can cause cardiac rhythm disturbances, leading to sudden death, and necessitate cardiac monitoring.
Conditional hospitals, generally in the coronary care unit (Coronary Care Unit, CCU) and intensive care unit (Intensive Care Unit, ICU) are equipped with electrocardiographic monitoring equipment. Some monitoring systems also have body temperature, oxygen saturation, respiratory rate, invasive or non-planning blood pressure monitoring function.
Some portable cardiac monitors are also equipped with a defibrillator, which is convenient for clinical resuscitation.
