The application of a medical mass spectrometer for the monitoring of respired gases in the respiratory intensive care unit of a community hospital is reviewed. This monitoring system is routinely used with intubated patients for periodic monitoring of end-tidal co2 tensions (PETCO2), FIO2, and PETO2 dead space to tidal volume ratios, and the determination of AaDO2; the value of these measurements is discussed. It is especially useful for continuous monitoring at critical points in the patient's… Expand

Although respiratory monitoring provides much useful information, it does not substitute for careful bedside examination, and a practical method of diagnosing respiratory muscle fatigue remains elusive. Expand
A Distributed Microprocessor Respiratory Intensive Care Monitoring System with Mass Spectrometer, Proximal Flowmeter, and Airway Pressure Transducer
Pressure monitoring at the proximal airway has been relatively easy — a number of ventilators feature continuous pressure monitoring and a variety of devices are available for airway pressure monitoring with low and/or high pressure alarms. Expand
Monitoring of respiratory function in critical care patients.
This section contains descriptions of machinery and procedures related to the respiratory care of surgical patients, and describes the practical pitfalls that are commonly encountered. Expand
Capnography in Critical Care Medicine
End-tidal CO2 measurements as a reflection of arterial CO2 tension in critically ill patients with respiratory or cardiovascular problems is limited, but it is still useful as a noninvasive monitor to alert clinicians of potential changes in a patient's cardiopulmonary condition. Expand
Breath-by-Breath End-Tidal Carbon Dioxide Analysis for Patients on Intermittent Mandatory Ventilation
Manufacturers of both mass spectrometers and infra-red analysers for measuring PetCO2 are marketing their systems for long-term, non-invasive assessment of the PaCO2. Expand
End-tidal carbon dioxide as a measure of arterial carbon dioxide during intermittent mandatory ventilation
Monitoring the maximalPetCO2, independent of breathing pattern, provides a clinically useful indicator of PaCO2 in postcardiotomy patients receiving intermittent mandatory ventilation. Expand
A Nasal Catheter for the Measurement of End-Tidal Carbon Dioxide in Spontaneously Breathing Patients: A Preliminary Evaluation
The results suggest that a balloon-tipped nasal catheter can provide a simple, easy, and reliable method for PETCO2 measurement in nontracheally intubated, spontaneously breathing patients. Expand
Capnometry for continuous postoperative monitoring of nonintubated, spontaneously breathing patients
It is concluded that this form of capnometry is well suited for continuous, noninvasive monitoring of respiration in nonintubated, spontaneously breathing patients. Expand

The transcutaneous oxygen monitor does not appear to be optimal as a respiratory monitor in the setting of ultralight general anesthesia where rapid, critical changes in oxygenation must be detected without delay. Expand
Use of a Microprocessor Controlled, Mass Spectrometer Based Monitoring System for Risk Management in a Community Hospital ICU
The study confirmed the previous work of Osborn and colleagues2,3, and Zwillich et al4 who also noted a disturbingly high number of adverse occurrences associated with respiratory care and mechanical ventilation. Expand
