capnogram

capnogram

 [kap´no-gram″]
a graphic representation of inhaled and exhaled carbon dioxide concentrations in the form of continuous waves.
 Normal capnogram. A, Carbon dioxide cleared from the anatomic dead space; B, dead space and alveolar carbon dioxide; C, alveolar plateau; D, end-tidal carbon dioxide tension (PETCO2). From Dorland's, 2000.

cap·no·gram

(kap'nō-gram),
A continuous record of the carbon dioxide content of expired air.

Most commonly seen in clinical practice is the time-based capnogram (see Figure 1, above).
When assessing a capnogram the following points should be noted: (6)
Neural network analysis of the volumetric capnogram to detect pulmonary embolism.
A capnograph produces both an EtCO2 value as well as a waveform, or capnogram.
Following insertion, the position of the cLMA was checked for airway patency by either observing the patient's respiratory movement and the capnogram when breathing spontaneously, or in apnoeic patients observing for chest expansion and the capnogram during manual ventilation.
After insertion, an initial assessment of ventilation was made after the device had been connected to the breathing system by either observing the patient's respiratory movement and the capnogram when breathing spontaneously or, in apnoeic patients (most cases), observing for chest expansion and the capnogram by gently squeezing the reservoir bag.
On commencement of mechanical ventilation after administration of the bronchodilator, both the capnogram and airway pressure were unremarkable.
Although accurate interpretation of the capnogram requires sophisticated knowledge, the ability to recognize the presence or absence of a waveform is all that is required for accurate assessment of inadvertent intrapulmonary placement using this method.
