We describe a single-posture method for deriving the proportionality constant (K) between rib cage (RC) and abdominal (AB) amplifiers of the respiratory inductive plethysmograph (RIP). Qualitative diagnostic calibration (QDC) is based on equations of the isovolume maneuver calibration (ISOCAL) and is carried out during a 5-min period of natural breathing(More)
Liquid silicone is an inert material that is utilized for cosmetic procedures by physicians as well as illegally by nonmedical personnel. We present a case report and collated clinical findings of 32 other patients who were hospitalized after illegal silicone injections. Symptoms and signs of the "silicone syndrome" included dyspnea, fever, cough,(More)
Drowning is a major cause of accidental deaths, especially in children. The most serious pathophysiologic consequence of near-drowning is hypoxemia, which usually is due to aspiration-induced noncardiogenic edema. Therefore, initial resuscitative efforts need to be directed at establishing adequate oxygenation and ventilation, followed by rewarming and(More)
STUDY OBJECTIVES To determine the usefulness of serial measurements of the rapid-shallow-breathing index (f/VT) as a predictor for successfully weaning elderly medical patients from mechanical ventilator support using a threshold value (< or =130) derived specifically for this population. DESIGN Prospective observational study using parameters suggested(More)
Placement and use of pulmonary artery catheters (PACs) carry potential risks. The authors describe a case of a patient who developed massive hemoptysis after placement of a PAC that caused a rupture of the pulmonary artery with pseudoaneurysm formation. Treatment was successfully achieved with transcatheter coil embolization. Pulmonary artery rupture and(More)
Many studies have shown that selected cardiac patients can be safely and economically cared for in intermediate care units rather than intensive care units. However, there are only limited data concerning intermediate care units for pulmonary patients. We prospectively followed up all Medicare patients from May 5, 1987, through May 4, 1988, who were(More)
The cost of delivering health care to Medicare patients in intensive care units (ICU), especially those on long-term ventilator support, has become a major financial burden to American hospitals. We established a central station, respiratory, noninvasive monitoring unit (NIMU) on a cardiac telemetry floor where nurse to patient ratio was 1:4 to 1:6 as a(More)
In conclusion, disseminated strongyloidiasis is a fatal disease that commonly affects the lungs. The disease should be suspected in an immunocompromised host who came from an area endemic for S stercoralis even years before the onset of symptoms or in patients with unexplained gram-negative bacteremia or meningitis. Treatment should be started promptly and(More)
We investigated the utility of a noninvasive respiratory inductive plethysmograph (RIP) to continuously monitor and record the breathing pattern of 44 patients who had been mechanically ventilated. Seven patients deteriorated on intermittent mandatory ventilatory rate of zero; seven deteriorated within 48 h following extubation; 30 were successfully(More)
Pregnancy induces significant physiologic stresses on the pulmonary and cardiovascular systems that may precipitate respiratory compromise. In addition, certain disease states that are unique to the pregnant woman, such as amniotic fluid emboli syndrome, may be associated with respiratory failure. The physiologic changes that affect the pregnant woman are(More)
