First, closely monitor the patient’s various electrocardiogram monitors, such as respiration, blood pressure, pulse rate, and oxygen saturation. If any abnormalities are found, report them immediately to the on-duty doctor and record them. Second, maintain the patient’s respiratory system smooth, and for patients with cerebrovascular disease, prevent food from entering the trachea due to choking during meals. When the patient vomits, the patient’s head should be tilted to one side to prevent the vomit from being aspirated into the lungs. Third, prevent the patient from falling out of bed, and immediately place the patient in a passive back tapping position to prevent bedsores and aspiration pneumonia.

The first priority in the care of critically ill patients is to implement general outpatient care protocols. Also, immediately evaluate the patient’s electrocardiogram, confusion, pupils, tongue, and pulse changes. Immediately prepare nursing records for critically ill patients. Closely monitor the condition and closely coordinate with the doctor for emergency treatment when the condition changes suddenly. When administering medication according to the doctor’s instructions, the oral order must be accurately transmitted before it can be used. Establish a venous safety channel quickly and provide oxygen immediately.

Familiarize yourself with the operation of electrocardiogram monitors, indwelling catheters, specimen collection, and preoperative preparation. For comatose patients, the appropriate position should be placed according to the condition. Do not move patients randomly when the blood pressure is unstable. Maintain smooth and proper fixation of various tubes to prevent falling off, bending, and blocking. Strictly adhere to the principles of aseptic operation to prevent infection. Provide dietary care according to the condition, and for patients who cannot eat, intravenous nutritional therapy can be provided.

For critically ill patients, the following medical care standards should be implemented: 1. Provide comprehensive multi-organ function tests for patients, such as detecting respiratory blood pressure, pulse rate, aortic oxygen saturation, body temperature, and urine, and make nursing records based on these main parameters. 2. Provide continuous low-flow oxygen therapy for patients, and adjust the total flow rate and concentration of CO2 according to the patient’s oxygen saturation. 3. Establish a venous safety channel for patients, carry out fluid resuscitation, and open two or more venous safety channels for rapid intravenous infusion if necessary. 4. For patients with severe conditions such as brain and cranial injuries, pay attention to brain protection, such as physical fever reduction of the head, and also carry out back tapping and sputum aspiration to prevent bedsores.
