Case Report 1
On Tuesday 22 March 1998, a 70-year-old, male patient, who was
known with COPD and had been treated for a week at the pulmonary
ward, was found in bed in cardiac and respiratory arrest. After
starting Basic Life Support, the nursing staff alerted the resuscitation
team. The patient was resuscitated according to the standards
of the European Resuscitation Council adhered to in this hospital.
After a short pre-oxygenation phase and intubation of the patient,
artificial respiration with the Oxylator® EM-100 was administered
manually (massage:ventilation ratio = 5:1). After about 10 minutes,
the respiration pressure exceeded 50 mm/g, which means that
the Oxylator® EM- 100 stopped hinctioning. The patient's
bronchi were cleared using a suction catheter, after which respiration
with the Oxylator® EM-100, with settings at 25 cmH2O and
in the automatic position, was resumed. Some 15 minutes later,
the patient regained a sinus rhythm and it was decided to continue
his treatment in the ICU. Re was monitored during the transport
by a DATEX AS3 light monitor with CO2 module, which
indicated CO2 values between 3.5 and 4.5 mmHg. During
the resuscitation in the patient's room, the Oxylator: EM-100
was driven by O2 from the hospital's central O2
system; for the transport, it was switched to a 2 litre O2
cylinder.
Case Report 2
An 18-year-old, male patient with an intra-cardial defibrillator
was being prepared for orthopaedic surgery; induction of anaesthesia,
which was expected to take a long time, was done in a preparing
room where automatic respiration is not customarily available.
Target Controlled infusion (propophol, esmeron and rapiphen)
was used to anaesthetise the patient. Before he was intubated,
manual respiration was applied via a mask with the aid of Oxylator®
EM-100, using jawthrust, until the patient had reached a state
of maximum relaxation. After endotracheal intubation, respiration
continued with the Oxylator® EM-100 in automatic setting
and at the previously set pressure of 25 cmH2O.
The preparations included the introduction of an arterial blood
pressure line and a central venous catheter. The entire induction
of anaesthesia and positioning took 30 minutes. In this special
situation, the procedure had to be managed without major changes
in the patient's blood pressure, which was successfully achieved. |
