Princinples II PULMONARY

QuestionAnswer
WHAT ARE PULMONARY SYSTEM MADE UP OF UPPER AIRWAY; MINUTE VENTILATION; LUNG VOLUME; AND ARTERIAL OXYGENATION
UPPER AIRWAY CAPILLARY ENGORGEMENT -MUCOSAL LINING -UPPER RESPIRATORY TRACT
IS THE VOCAL CORD AND THE ARYTEMOIDS SWOLLEN YES. THEY ARE EDEMATOUS
HOW MUCH DOES THE MINUTE VENTILATION DECREASE BY ABOUT 50 % DURING THE FIRST TRIMESTER. -TV 40% -RR 10%
WHAT HAPPEN TO PROGESTERONE STIMULATED AND INCREASES MV
WHAT DOES PROGESTERONE DON TO PACO2 IT RESULTS IN A DECREASED RESTING MATERNAL PACO2 -FROM 40 MMHG TO 30 MMHG. -NO CHANGES IN PH (RENAL EXCRETION OF BICARB IONS).
WHAT HAPPEN TO LUNG VOLUME IN THE 3RD MONTH OF PREGNANCY DIAPHRAGM CEPHALAD -DECREASED FRC - 20 % (TERM) -FRC<CLOSING CAPACITY >>ATELECTASIS (SUPINE)
WHAT IS THE ANESTHESIA CONSIDERATION INCREASE MINUTE VENTILATION; DECREACED FRC => INCREASED ALVEOLA CONCENTRATIONS OF INHALED ANESTHETICSS
WHAT IS FRC RV + ERV
CONSIDERATIONS RELATED TO CHANGES IN THE PULMONARY SYSTEMS ARE SELECT A SMALLER CUFFED ETT (6.0-7.0) AVOID NASAL AIRWAYS ( VASCULAR CONGESTION) WEIOGHT GAIN, SHORT NECK AND LARGE BREASTS. ****CONSIDER DIFFICULT AIRWAY. RAPID ALVEOLAR CONCENTRATIONS OF 1A RAPID DESATURATION WITH APNEA PREOXYGENATE, OXYGENATE DURI
WHAT MAY HELP DURING DL STUBBY HANDEL ON LARYNGOSCOPE MAY HELP
