“…1 Apart from the advantages of being a continuous and non-invasive monitor of exhaled carbon dioxide (CO 2 ), it is also a reliable indicator of partial pressure of CO 2 (PaCO 2 ) in arterial blood and is often used as its surrogate. 2 Changes in EtCO 2 and PaCO 2 normally parallel each other and the difference between the two is approximately 3.6 to 4.6 mm Hg in healthy awake patients. 3 We report a case where EtCO 2 values were disproportionately high and did not correlate with PaCO 2.…”

End-tidal carbon dioxide (EtCO2) monitoring has now become the standard of care not only during anesthesia but also in intensive care units for patients on mechanical ventilation, emergency department, and pre-hospital settings to confirm and monitor the correct placement of endotracheal tube. It is a non-invasive and continuous method of measuring exhaled carbon dioxide (CO2). Continuous waveform capnography measures EtCO2 and monitors ventilation. EtCO2 often correlates with partial pressure of carbon dioxide in arterial blood (PaCO2) and is a reliable indicator of PaCO2. A rise in EtCO2 often implies increased production of CO2 or decreased excretion (rebreathing, decrease ventilation) of CO2. We report an unusual case where the monitor malfunction per se lead to spuriously increased EtCO2 values without any clinical cause and did not correlate with PaCO2, thereby re-emphasizing that various monitors must always be interpreted in correlation with clinical observation.

“…As a reflection of this potential benefit, the ASA has identified CO 2 monitoring as a standard of care in anesthesia monitoring since 1986. 28 In healthy patients during mechanical ventilation, P ETCO 2 closely approximates P aCO 2 and is usually 2-5 mm Hg lower [29][30][31] and therefore can be an effective index of the adequacy of ventilation (see Fig. 1).…”

In the past few decades, assessment of exhaled CO2 in both intubated and non-intubated patients has evolved into an essential component in many aspects of patient monitoring. Besides the basic assessment of ventilation, exhaled CO2 monitoring can provide valuable patient safety information and critical physiologic data in regard to the ventilation and perfusion matching in the lungs, cardiac output, and metabolic rate. Despite these important clinical monitoring benefits and widespread availability, exhaled CO2 monitoring is often underutilized. The purpose of this paper is to review the importance and present the extensive body of knowledge to support the use of exhaled CO2 monitoring in various areas of clinical practice. Advanced application concepts and the future development of exhaled CO2 monitoring will also be discussed.

AbstrakPasien dengan ventilasi mekanik perlu dilakukan pemantauan CO 2 karena berperan penting pada regulasi pernapasan dan keseimbangan asam-basa tubuh. Pemantauan CO 2 dapat dilakukan dengan mengukur PaCO 2 melalui analisis gas darah arteri. Pengukuran PaCO 2 tidak dapat dilakukan secara kontinu sehingga perlu sering dilakukan pengambilan darah arteri yang dapat menimbulkan komplikasi. Pengukuran PETCO 2 dapat memantau CO 2 secara kontinu dan non invasif. PETCO 2 adalah tekanan parsial CO 2 ekspirasi yang diukur pada saat akhir volume tidal pernapasan. Penelitian ini bertujuan membandingkan nilai PETCO 2 dan PaCO 2 pada pasien dengan ventilasi mekanik di ruang GICU RSUP Dr. Hasan Sadikin Bandung. Rancangan penelitian yang digunakan adalah prospective cross sectional. Pemilihan sampel dilakukan secara consecutive sampling. Penelitian dilakukan terhadap 21 pasien yang menggunakan ventilasi mekanik di ruang GICU RSUP Dr. Hasan Sadikin Bandung. Data PETCO 2 dicatat pada saat perawat mengambil sampel darah arteri untuk pemeriksaan analisis gas darah. Didapatkan 122 pasang data nilai PETCO 2 dan PaCO 2 . Data yang diperoleh dianalisis dengan Bland-Altman plot. Hasil penelitian nilai PETCO 2 berada pada rentang 14-67 mmHg dan nilai PaCO 2 berada pada rentang 17-77 mmHg. Bias nilai PETCO 2 dan PaCO 2 adalah -4,6475 mmHg lebih rendah daripada estimasi nilai bias ±5 mmHg sehingga bisa diterima secara klinik. Presisi nilai PETCO 2 adalah 12,7969 mmHg (limit of agreement= 1,7509; -11,0460) lebih tinggi daripada estimasi nilai presisi ±5 mmHg sehingga tidak bisa diterima secara klinik. Kesimpulan dari penelitian ini adalah pengukuran PETCO 2 tidak dapat menggantikan pengukuran PaCO 2 , tetapi pengukuran PETCO 2 dapat digunakan untuk memperkirakan nilai PaCO 2 pasien dengan ventilasi mekanik.Kata kunci: PETCO 2 , PaCO 2 , ventilasi mekanik. Comparison of PETCO 2 and PACO 2 Values in Patients with Mechanical Ventilation AbstractPatients with mechanical ventilation need to be monitored for the CO 2 value because it has an important role in regulation of respiration and body acid-base equilibrium. Monitoring of CO 2 can be done by measuring PaCO 2 through arterial blood gas analysis. Measurement of PaCO 2 could not be done continuously so that the arterial blood are needed to be taken quite often which could cause complication. The measurement of PETCO 2 can monitor the CO 2 continuously and non-invasively. PETCO 2 is partial pressure of CO 2 expiration that is measured at the end of respiration tidal volume. This study aimed to compare the PETCO2 value and PaCO 2 in patients with mechanical ventilation in GICU Dr. Hasan Sadikin Hospital. The research design was prospective crosssectional using consecutive sampling method. The total sample was 21 patients who used mechanical ventilator in GICU Dr. Hasan Sadikin Hospital Bandung. The PETCO 2 data were recorded when the patients' arterial blood sample were taken for blood gas analysis test. The total of 122 pair date of PETCO 2 and PaCO 2 values were recorded. The data were anal...
