Disease relevance of Capnography

• Monitoring with capnography allowed for rapid titration of propofol at the earliest signs of respiratory depression [1].
• Breathing stability was estimated by at least 6 h of capnography and from these records apnea index (AI, episodes/hour) and cyclic changes of end-tidal CO2 (c-PETCO2, cycles/hour) were derived [2].
• Pneumotachography, capnography and airway occlusion pressures at 0.1 s (P degree 0.1) were used before and during both mild hypoxia (end-tidal O2 tension 8.7 kPa) and hypercapnia achieved by an inspired CO2 concentration of 5% [3].

Psychiatry related information on Capnography

• By combining capnography, during the Effort Test, with analysis of blood gases and specific electrolytes, the effort-syndrome hypothesis was further tested in the present study [4].

High impact information on Capnography

• CONCLUSIONS: Gastroenterologist-administered propofol using monitoring with capnography is similar to meperidine/midazolam for both physiological outcomes and patient/endoscopist satisfaction [1].
• Capnography poorly estimated Pa(CO(2)) during exercise at 1 and 2.8 ATA because of wide variability [5].
• A response to 'Another use for capnography', White SM, Anaesthesia 2003; 58: 189-90 [6].
• Capnography and severe COPD [7].
• Capnography via the LTA: friend or foe [8]?

Biological context of Capnography

• Pulse rate, blood pressure, blood gases (PaO2 and PaCO2) and pH, blood lactic acid concentration, and capnography were used to evaluate the physiologic responses of sea turtles to isoflurane [9].
• The sedative effect was evaluated and measurements by pneumotachography and in-line capnography were made immediately after induction of sleep, just before the start of surgery, during surgery and after surgery both before and after 3 min of about 2% CO2 inhalation [10].

Anatomical context of Capnography

• During routine capnography a rise of the end expiratory volume percentage CO2 was seen after releasing the tourniquet cuff in cases of orthopedic operations on the lower extremities under bloodless conditions [11].

Associations of Capnography with chemical compounds

• Capnography, the science of CO2 waveforms analysis, can play a role in the management of mechanically ventilated patients [12].
• This article discusses the clinical applications and limitations of capnography and end-tidal CO2 monitoring [13].
• Capnography and measurement of the respiratory minute volume were carried out on normal, conscious subjects during breathing of pure O2 via a Mapleson C modification of a Magill attachment, with and without continuous gas evacuation [14].
• METHODS: The authors performed continuous capnography on a convenience sample of 20 ED pediatric patients who received ketamine 1.5 mg/kg IV for procedural sedation [15].
• OBJECTIVES: 1) To evaluate the relationship between measured serum bicarbonate (HCO(3)) and ETCO(2) measured via nasal capnography in children with suspected DKA; and 2) to assess the ability of capnography to predict DKA [16].

Gene context of Capnography

• Pulmonary function measurements in dolphins using capnography [17].
• Misleading capnography in primary pulmonary hypertension [18].
• BACKGROUND: The Royal College of Anaesthetists and the Association of Anaesthetists of Great Britain and Ireland recommend the use of capnography to ensure correct tracheal tube placement in the theater environment [19].
• Increases in CBFV and CBF seen in previous studies may be related to an increasing PaCO2 when maintenance of normocarbia is based on only real-time capnography with a constant PetCo2 rather than additional arterial blood gas monitoring [20].

Analytical, diagnostic and therapeutic context of Capnography

• This report, of a 16-month-old child recovering from surgery for a posterior fossa tumour, illustrates how pneumotachography, capnography and occlusion testing before and during CO2 challenge can be of clinical value in the analysis of a difficult respiratory disturbance in the early postoperative period [21].
• Several CO2 detection devices are suitable for emergency transport, including colorimetry, capnometry, and capnography [22].
