EMTs, nurses, and other types of clinicians learn valuable information by studying a patient's capnogram. It helps predict the outcome of resuscitation, it helps observe cardiac output during CPR and helps monitor a seated patient.
A waveform capnogram is a vital sign that provides clinicians with information about a patient's ventilation. Understanding capnography helps clinicians objectively assess a patient's ventilatory status. It does this by tracking the carbon dioxide in the patient's breath. Understanding capnography also provides clinicians with clues about the circulatory and metabolic systems, which can help in planning a patient's treatment. Here, we recommend you ekingst waveform capnography device.
The most basic use of a capnogram is to monitor a patient's ventilation. It provides a number and a graph that allow clinicians to assess respiratory trends. Understanding capnography can provide early warning signs of an impending crisis. When a person hyperventilates, their carbon dioxide levels decrease. Hyperventilation is a symptom of many different conditions, from anxiety to bronchospasm. CO2 levels also decrease during cardiac arrest, hypotension, reduced cardiac output, and severe pulmonary edema.
When a person is hypoventilating, their carbon dioxide rises. Hypoventilation can be caused by a variety of conditions including head trauma, stroke, drug overdose, sedation, and even poisoning. Patients may be high in CO2 due to increased respiration, fever, pain, respiratory depression, sepsis, or even chronic hypercapnia.
Some diseases can also cause a patient's CO2 to rise and then fall, such as asthma. When understanding capnography, it is more important to focus on the trend of the graph than the specific numbers. If you start to see the graph go up steadily, the patient may soon need intubation or assistance with breathing. In the case of a heroin overdose, some states allow clinicians to use Narcan in unresponsive patients with a suspected opioid overdose and a respiratory rate of less than 10 breaths. Monitoring a patient's carbon dioxide level can help clinicians better assess a patient's ventilation.
Capnography can also show hypoxic drive in COPD maintainers. Knowing that CO2 levels on the capnogram will steadily rise alerts the clinician to turn on oxygen before the patient becomes sluggish. Hypoxic drive occurs in only about 5% of COPD patients. In these patients, monitoring CO2 levels will help you determine if the patient's oxygen levels are correct and prevent hypoventilation.
