Abstract:
We introduce change in pulse transit time (change in PTT: noninvasive intrathoracic pressure monitoring) as a new monitoring test of sleep apnea syndrome, which is being developed for clinical application. In addition, we report the kinetics of cardiogenic oscillation (CGO: noninvasive upper airway obstruction monitoring), which was published in this journal in 2003, and the response of the upper airway in clinical practice (under an endoscope). We also review diaphragmatic movement by abdominal echography (respiration generator monitoring).

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
Assessment of Airway, Skin Color, and Use of Accessory Muscles

Assessment of Respiration
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...
